Answer:
[tex]x\le 400-23\\ \\x\le 377\ pounds[/tex]
Step-by-step explanation:
The winner of a weight-lifting competition bench-pressed weight 400 pounds.
All other competitors bench-pressed at least 23 pounds less. So, the maximum weight that all other competitors bench-pressed is
[tex]400-23=977\ pounds[/tex]
If x pounds is the weight that the other competitors bench-pressed, then
[tex]x\le 400-23\\ \\x\le 377\ pounds[/tex]
that sounds as the other competitors bench-pressed at most 377 pounds weight.
what is the answer to
6x + 7 = 13 + 7x
x = -6 is the solution to the equation 6x + 7 = 13 + 7x
To solve the equation 6x + 7 = 13 + 7x, you can follow these steps:
Group the x terms on one side and the constant terms on the other side:
6x - 7x = 13 - 7
Combine like terms:
-x = 6
Multiply both sides of the equation by -1 to isolate x:
-1*(-x) = -1*6
This simplifies to:
x = -6
Therefore, the solution to the equation 6x + 7 = 13 + 7x is x = -6.

a cookie recipe calls for 1 2/3 of sugar if you plan on changing the recipe to make it 2 1/2 times as much how many cups of sugar will you need
Pls show work
Answer:
[tex]4\frac{1}{6}\ cups[/tex]
Step-by-step explanation:
we know that
The recipe calls for 1 2/3 of sugar
To make 2 1/2 times the recipe
Multiply 2 1/2 by 1 2/3
Convert mixed numbers to an improper fraction
[tex]1\frac{2}{3}=\frac{1*3+2}{3}=\frac{5}{3}\ cups[/tex]
[tex]2\frac{1}{2}=\frac{2*2+1}{2}=\frac{5}{2}[/tex]
so
[tex]\frac{5}{2}(\frac{5}{3})=\frac{25}{6}\ cups[/tex]
Convert to mixed number
[tex]\frac{25}{6}=\frac{24}{6}+\frac{1}{6}=4\frac{1}{6}\ cups[/tex]
Final answer:
To find out how much sugar is needed for the new recipe that is 2 1/2 times as much, follow the three-step process.
Explanation:
To find the amount of sugar needed:
Calculate 1 2/3 cups of sugar is equal to 5/3 cups of sugar.
Multiply 5/3 by 2 1/2, which equals 25/6.
Convert 25/6 to a mixed number, which is 4 1/6 cups of sugar needed for the new recipe.

[2+(-4)]+5-[(-11)x(-2)]-(-7)
Answer: -12
Step-by-step explanation:
[2+(-4)] becomes (2-4), or -2, and 5-[(-11)x(-2)]-(-7) becomes 5-22+7, so the entire thing is -2+5-22+7, so it is -12.
The given expression [2+(-4)]+5-[(-11)x(-2)]-(-7) simplifies to -12.
To simplify the given expression, we follow the order of operations (PEMDAS/BODMAS):
Step 1: Evaluate the innermost parentheses:
[2 + (-4)] + 5 - [(-11) x (-2)] - (-7)
[2 - 4] + 5 - [(-11) x (-2)] - (-7)
Step 2: Complete the operations inside the brackets:

−2 1/4=r−4/5
What is r?
Answer:
r = -29/20 or r = -1.45
Step-by-step explanation:
I believe you are saying that the equation is -2 1/4 = r - 4/5. If so, then I would solve it in this way:
-2 1/4 = r - 4/5
-9/4 = r - 4/5
-9/4 (20) = r (20) - 4/5 (20)
-45 = 20r - 16
20r = -29
r = -29/20
r = -1.45
Check:
-2 1/4 = r - 4/5
-9/4 = r - 4/5
-2.25 = r - 0.8
-2.25 = -1.45 - 0.8
-2.25 = -2.25
-9/4 = -9/4
The calculated value of variable r is r = -1.45.
What is equation?An equation is a mathematical statement that shows the equality between two expressions. It typically consists of variables, constants, and mathematical operations (e.g., addition, subtraction, multiplication, division) with an equal sign (=) in between.
To solve for r in the equation -21/4 = r - 4/5
Step 1: Add 4/5 to both sides of the equation to isolate r:
r = -2.25 + 4/5
Convert -2.25 to a fraction with a common denominator of 5:
r = (-11.25/5) + (4/5)
Add the fractions:
r = (-11.25 + 4)/5
Simplify:
r = -7.25/5
r = -1.45
So, r = -1.45.

If |z - 7| - 2 = 2, then z = -3 /amp; z = -11 true or false
Answer:
False
Step-by-step explanation:
The absolute value always returns a positive value, however the expression inside can be positive or negative, that is
Given
| z - 7 | - 2 = 2 ( add 2 to both sides )
| z - 7 | = 4, then
z - 7 = 4 OR - (z - 7) = 4
z = 4 + 7 = 11 OR
- z + 7 = 4
- z = 4 - 7 = - 3 ( multiply both sides by - 1 )
z = 3
As a check
z = 11
| 11 - 7 | - 2 = | 4 | - 2 = 4 - 2 = 2 ← True
z = 3
| 3 - 7 | - 2 = | - 4 | - 2 = 4 - 2 = 2 ← True
Hence z = 11 or z = 3 are the solutions
Lucinda has a pocketful of dimes and quarters with a value of $6.20. The number of dimes is 18 more than 3 times the number of quarters. How many dimes and how many quarters does Lucinda have?
Answer:
The number of dimes is 42 and the number of quarters is 8
Step-by-step explanation:
Let
x -----> the number of dimes
y -----> the number of quarters
Remember that
1 dime=$0.10
1 quarter=$0.25
we know that
0.10x+0.25y=6.20 -----> equation A
x=3y+18 ----> equation B
Solve the system by graphing
Remember that the solution is the intersection point both graphs
The solution is the point (42,8)
see the attached figure
therefore
The number of dimes is 42 and the number of quarters is 8
There are 42 dimes and 8 quarters

We can state the problem in the form of algebraic equations
Lucinda has a pocketful of dimes and quarters with a value of $ 6.20
we translate this sentence into Algebraic expressions:
dime = D = $ 0.10
quarter = Q = $ 0.25
Then the equation becomes:
0.1D + 0.25Q = 6.20The number of dimes is 18 more than 3 times the number of quarters
we translate this sentence into Algebraic expressions:
D = 18 + Q
D - 3Q = 18
We solve the two equations with substitution and elimination
1. elimination
0.1D + 0.25Q = 6.20 x 10
D - 3Q = 18 x 1
------------------------------------
D + 2Q = 62
D - 3Q = 18
----------------------------------- -
5.5Q = 44
Q = 8
2. substitution
D - 3Q = 18
D - 3.8 = 18

Lilly and Rose are playing a game. In the game, each player starts with 0 points and the player with the most points at the end wins. Lilly gains 5 points two times, loses 12 points/ and then gains 3 points. rose loses 3 points two times, loses 1 point, gains 6 points, and then gains 7 points.
A. write and evaluate an expression to find Lillys score.
B. write and evaluate an expression to find Roses score
C. Who won the game, and why?
Answer:
Rose wins the game, with 6 points over Lilly's 1 point.
Step-by-step explanation:
Let's find Lilly's score. In this example we will add together the gains first, so we wouldn't have to deal with negative numbers, and after, we subtract the losses of each person.
Lilly's points:
[tex]0 + 5 + 5 + 3 - 12 = 1[/tex]
Rose's points:
[tex]0 + 6 + 7 - 3 - 3 - 1 = 6[/tex]
Rose wins the game with a 5 point lead.
Lilly's score is 1 and Rose's score is 6. Therefore, Rose wins the game because 6 is greater than 1.
Explanation:To find Lilly and Rose's score, we will create and solve an expression that reflects each player's game moves.
A. Lilly's score:
Lilly gains 5 points two times, loses 12 points, and then gains 3 points. We can express this as (5*2) - 12 + 3. First, we multiply 5 by 2, which equals 10. Then, we subtract 12 from 10, which gives -2. Finally, we add 3 to -2, resulting in a final score of 1 for Lilly.
B. Rose's score:
Rose loses 3 points two times, loses 1 point, gains 6 points, and gains 7 points. We can write this as (-3*2) - 1 + 6 + 7. First, we multiply -3 by 2, which equals -6. Then, we subtract 1 from -6 yielding -7. After that, we add 6 to -7, getting -1. Lastly, we add 7 to -1, resulting in a final score of 6 for Rose.
C. Game result:
Rose won the game because her final score of 6 is higher than Lilly's final score of 1.

Find the distance between the points (a, 0) and (0, b).
Answer:
d = sqrt( a^2 + b^2)
Step-by-step explanation:
Formula
d = sqrt( (x2 - x1)^2 + (y2 - y1)^2 )
Givens
x1 = a
x2 = 0
y1 = 0
y2 = b
Solution
d = sqrt( (0 - a)^2 + (b - 0)^2 )
d = sqrt( a^2 + b^2)
which is another way of writing the Pythagorean theorem.
To find the distance between points (a, 0) and (0, b), use the distance formula which results in √(a² + b²). This involves calculating the square root of the sum of the squares of the coordinates.
Therefore, the final distance is √(a² + b²).
Finding the Distance Between Two Points
To find the distance between two points (a, 0) and (0, b), we use the distance formula:
Distance formula: d = √((x2 - x1)² + (y2 - y1)²)
Let's denote the points as:
Point 1: (a, 0)
Point 2: (0, b)
Applying the coordinates to the distance formula, we get:
d = √((0 - a)² + (b - 0)²)
Simplifying inside the square root:
d = √(a² + b²)
So, the distance between the points (a, 0) and (0, b) is √(a²+ b²).
