Answer:
No solution/ Not possible
Step-by-step explanation:
Let's write out the equation
4x-2+x= 2x+8+3x
First thing we should do is look and see if there are any like terms that we can combine
4x+x-2=2x+3x+8
5x-2=5x+8
Then we want to get x on one side
By adding 2 to both sides
5x=5x+10
0=10
This is false, so the answer to this is No solution
what is 271,403 to the nearest thousand
Answer:
300,000
Step-by-step explanation:
hope this helps
Answer:
271,000
Step-by-step explanation:
Rounding depends on the place value, if you are rounding to the nearest thousand, look at the number in the hundred place. Is that number lower or higher than 5? If lower, the place you are rounding to stays the same, and the places below it turn to zeros. If 5 or higher, round up, add 1 to the place you are rounding to, then turn the places below to zeros.
In this case, the hundreds place is a 4. Meaning you round down.
16. Which number has the greater value,
7 x 10-9 or 6 x 10-4?
in any case, the amount of zeros is more important than the significant digits. since 7X10-9 has a smaller exponent above the 10 than 6X10-4, it is safe to say 6X10-4 is the larger number
Answer:
7 x 10-9
Step-by-step explanation:

A large western state consists of 2691 million acres of land. Approximately 65% of this pand is federally owned how to find the answer?
Answer:
Step-by-step explanation:
What you need to do is take your 65% and put it over 100% like this: 65/100
Then, you take 2691 and put it into the denominator and put x on the top like this: x/2691
Then you need to put them equal to each other and cross multiply like this 65/100=x/2691
Multiply the 2691 by 65 and x by 100
to get 100x=2691(65)
Finally, multiply the 2691 by 65 and then divide that whole thing by 100 to get x.
x will be the land in acres and your final answer.
Good luck! Hope this was clear!
65% of the total acres of the large western state is approximately 1749.15 million acres.
To find the answer:
Calculate 65% of 2691 million acres.
Divide the result by 100 to get the amount federally owned.
Therefore, the federally owned land in the large western state is approximately 1749.15 million acres.
Mike wants to make meatloaf. His recipe
uses a total of 4 pounds of meat.
If he uses a 3 to 1 ratio of beef to pork, how
much pork will he use? Enter your answer as a
mixed number in simplest terms.
Total meat in the recipe he wants to use = 7 pounds
Beef : pork = 3 : 1
Total pork that he will use = x 7 pounds
= 7/4 pounds
hope this helps
Answer:
Amount of pork used was 1 pound.
Step-by-step explanation:
Mike wants to make meatloaf by adding beef and pork.
Ratio of the meat (beef and pork) is = 3 : 1
Recipe requires total amount of meat = 4 pounds
So the amount of pork used in the recipe = [tex]\frac{1}{(1+3)}\times 4[/tex]
= [tex]\frac{1}{4}\times 4[/tex]
= 1 pound
Therefore, total amount of pork used in the recipe is 1 pound.

Jackie cut a 2-yard spool into 5 equal lengths of ribbon.
a. What is the length of each ribbon in yards? Draw a tape diagram to show your thinking.
b. What is the length of each ribbon in feet? Draw a tape diagram to show your thinking.
Answer:
a. [tex]\frac{2}{5}[/tex] yard
b. 1.2 feet
Step-by-step explanation:
a. Jackie cut a 2-yard spool into 5 equal length of ribbon.
We will divide 2 yard by 5 = 2 ÷ 5 = [tex]\frac{2}{5}[/tex] yard
5 units = 2 yard
1 unit = [tex]\frac{2}{5}[/tex] yard
Check : [tex]\frac{2}{5}[/tex] + [tex]\frac{2}{5}[/tex] + [tex]\frac{2}{5}[/tex] + [tex]\frac{2}{5}[/tex] + [tex]\frac{2}{5}[/tex] = [tex]\frac{10}{5}[/tex] = 2
b. Length of each ribbon in feet
Since 1 yard = 3 feet
therefore, 2 yard = 3 × 2 = 6 feet
6 feet in to 5 equal part = 6 ÷ 5
= 1.2 feet
check : 1.2 + 1.2 + 1.2 + 1.2 + 1.2 = 6.0 feet
Each ribbon cut from a 2-yard spool into 5 equal parts will be 0.4 yards or 1.2 feet in length. Tape diagrams represent this division into equal parts.
Explanation:To determine the length of each ribbon when a 2-yard spool is cut into 5 equal lengths, you need to divide the total length by the number of pieces.
2 yards ÷ 5 = 0.4 yards for each piece.To represent this with a tape diagram, imagine a line equally divided into 5 sections, with each section representing 0.4 yards.
For the length in feet, since 1 yard equals 3 feet, we multiply the length in yards by 3.
To show this with a tape diagram, you can divide a line into 5 sections with each section representing 1.2 feet.
Find three consecutive integers so that the
sum of the first two integers is 10 more than the third
integer.
Final answer:
The three consecutive integers that satisfy the condition are 11, 12, and 13. These numbers are such that the sum of the first two is equal to the third integer plus 10.
Explanation:
The question asks to find three consecutive integers where the sum of the first two is 10 more than the third. To solve this, let's call the smallest integer 'x'. Therefore, the next two consecutive integers will be 'x+1' and 'x+2'. The problem states that the sum of the first two integers is 10 more than the third, which gives us the equation: x + (x + 1) = (x + 2) + 10.
Simplifying this equation gives us 2x + 1 = x + 12. To find the value of 'x', we subtract 'x' from both sides of the equation, which gives us x + 1 = 12. Next, we subtract 1 from both sides to get x = 11. The three consecutive integers in question are therefore 11, 12, and 13.
Checking our work: the sum of the first two integers is 11 + 12 = 23. The third integer plus 10 is 13 + 10 = 23. Since both sums are equal, our solution is correct.
Final answer:
To find three consecutive integers, let the first integer be x, the second integer be x+1, and the third integer be x+2. Solve the equation x + (x+1) = (x+2) + 10 to find x, then determine the three consecutive integers.
Explanation:
To find three consecutive integers, we can let the first integer be x, the second integer be x+1, and the third integer be x+2. We are given that the sum of the first two integers is 10 more than the third integer. This can be written as:
x + (x+1) = (x+2) + 10
Combining like terms and solving the equation, we get:
2x + 1 = x + 12
x = 11
So the three consecutive integers are 11, 12, and 13.
If a+b-c=3 what is the value of 4(a+b-3)-(a+b+3c)?
3abc
Step-by-step explanation:
Final answer:
To find the value of 4(a+b-3)-(a+b+3c) given that a+b-c=3, we simplify to 3(a + b - c) - 12. Since a + b - c equals 3, the expression simplifies to -3.
Explanation:
The question provides the equation a + b - c = 3. To find the value of the expression 4(a+b-3)-(a+b+3c), we can simplify it using the given equation.
Let's break down the steps for simplification:
First, substitute the value of a + b - c from the given equation, which is 3, into the expression we want to simplify.Then, distribute the 4 across the first set of parentheses 4(a + b - 3) which becomes 4a + 4b - 12.Now, combining this result with the second part of the expression -(a + b + 3c) gives us 4a + 4b - 12 - a - b - 3c.Grouping like terms together and simplifying gives us 3a + 3b - 3c - 12 which is equivalent to 3(a + b - c) - 12.Since a + b - c = 3, the expression becomes 3(3) - 12, which simplifies to 9 - 12.Thus, the final value of the expression is -3.
What is the minimum number of members of the Senate that must approve a treaty for it to go
into effect?
Answer:
Two thirds of the Senate must approve it
The minimum number of Senate members needed to approve a treaty is two-thirds of the Senate.
Explanation:The minimum number of members of the Senate that must approve a treaty for it to go into effect is two-thirds (⅔) of the Senate. The Constitution of the United States, Article II, Section 2, Clause 2 states that the President has the power to make treaties, but they require the advice and consent of the Senate.
For example, if the Senate has 100 members, then 67 votes would be needed to approve a treaty for it to go into effect. However, it is important to note that the Senate may require a supermajority vote, which would mean a higher percentage of approval than two-thirds, depending on their rules and procedures.

The correct answer is the first one,
[tex] - 1 < x < 7[/tex]
Final answer:
To solve the given inequalities, (x - 2) < 5 and (x + 7) > 6, first isolate x in each one to get x < 7 and x > -1. The intersection of these solutions, which is the final answer, is -1 < x < 7.
Explanation:
The student has asked to solve two inequalities and find the intersection of their solutions. The inequalities are (x - 2) < 5 and (x + 7) > 6. To solve these separately:
For the first inequality, add 2 to both sides to get x < 7.
For the second inequality, subtract 7 from both sides to get x > -1.
To find the intersection, we look for values that satisfy both conditions: x > -1 and x < 7. Therefore, the solution is the set of all x such that -1 < x < 7.
solve the inequality: | x/4 - 7 | < -2
Answer:

[tex]\left|\dfrac{x}{4}-7\right|<-2[/tex]
We know: absolute value is always non-negative.
Therefore, this inequality has no solution.
20. Acid Mixture Bill Charlson needs 10% hydrochloric acid
for a chemistry experiment. How much 5% acid should he
mix with 60 milliliters of 20% acid to obtain a 10% solution?
Answer:
120 ml
Step-by-step explanation:
Let x ml of 5% acid should mix with 60 milliliters of 20% acid to obtain a 10% solution,
Thus, the quantity of resultant mixture = ( x + 60 ) ml,
Also,
Acid in x ml 5% acid + Acid in x ml 5% acid = acid in 10% resultant solution,
5% of x + 20% of 60 = 10% of ( x + 60)
[tex]\frac{5x}{100}+\frac{20\times 60}{100}=\frac{10\times (x+60)}{100}[/tex]
[tex]5x + 1200 = 10x + 600[/tex]
[tex]5x - 10x = 600 - 1200[/tex]
[tex]-5x = -600[/tex]
[tex]\implies x = \frac{-600}{-5}=120[/tex]
Hence, 120 ml of 5% acid should be mixed.

b. If the group also purchases IMAX movie tickets for an additional $4 per student, what is the new total cost of all the tickets? Write an expression that shows how you calculated the new price.
Answer:
(a) $2,375.
(b) $2,875.
Step-by-step explanation:
We have been general admission to The American Museum of Natural History is $19.
(a). To find the total cost of tickets for a group of 125 students, we will multiply 125 by $19.
[tex]\text{The total cost of tickets}=\$19\times 125[/tex]
[tex]\text{The total cost of tickets}=\$2,375[/tex]
Therefore, the total cost of 125 tickets would be $2,375.
(b). We have been given that the group also purchases IMAX movie tickets for an additional $4 per student.
The total cost of one ticket would be the cost of museum ticket plus movie ticket that is [tex]\$19+\$4=\$23[/tex].
The new total cost of 125 tickets would be 125 times $23.
[tex]\text{The new total cost of tickets}=\$23\times 125[/tex]
[tex]\text{The new total cost of tickets}=\$2,875[/tex]
Therefore, the new total cost of 125 tickets would be $2,875.

How can you determine the coordinates of any image that is dilated with the center of dilation at the origin without graphing
Answer:
[tex](x,y)\rightarrow (kx,ky)[/tex]
Step-by-step explanation:
A dilation is an enlargement or reduction of an object by a scale factor and with a center of dilation. The scale factor refers to the change in size. The center of dilation is a point about which we are dilating an object.
The dilation with the center of dilation at the origin and a scale factor of k has the rule
[tex](x,y)\rightarrow (kx,ky)[/tex]
This means that the image of the point with coordinates (x,y) after the dilation by a scale factor of k with center of dilation at origin will have coordinates (kx,ky).
