What is 2(log38+logzz)-log3(34 – 72) written as a single logarithm?
To simplify the given expression, we can use the properties of logarithms. By using the product, power, and quotient rules of logarithms, we can combine the terms and simplify the expression into a single logarithm.
Explanation:To simplify the given expression 2(log(38) + log(zz)) - log3(34 - 72), we can use the properties of logarithms.
Start by using the product rule of logarithms to combine the terms inside the parentheses: log(38zz).Now, use the power rule of logarithms to bring the exponent out as a coefficient: log(38) + log(zz).Next, apply the quotient rule of logarithms to subtract the logarithm of the denominator: log(38) + log(zz) - log3(-38).Finally, simplify the expression: log(38zz/(-38)).This is the single logarithm form of the given expression.

Write a number in the blank space so that the equation will have an infinite number of solutions
The answer is 3x + 5 = 3x - ______ has infinitely many solutions- type a number only
Answer: 5
Step-by-step explanation:
3x + 5=3x - 5
Final answer:
To achieve an infinite number of solutions in the equation '3x + 5 = 3x - ______', the blank should be filled with the number 5, making both sides of the equation identical and true for all values of x.
Explanation:
To make an equation have an infinite number of solutions, both sides of the equation must be identical. Looking at the equation 3x + 5 = 3x - ______, we want to find the number that would make the statement an identity.
The only way for this equation to have infinite solutions is if the variable terms (3x) are equal and the constant terms are also equal. Hence, the blank must be filled with the number 5, making the equation 3x + 5 = 3x + 5, which is true for all values of x.

Solve for b. 9000-b=-11,000+b
Answer:
b=10,000
Step-by-step explanation:
[tex]9,000-b=-11,000+b[/tex]
Regroup terms
[tex]9,000-b=b-11,000[/tex]
Add b to both sides
[tex]9,000-b+b=b+b-11,000\\9,000=2b-11,000[/tex]
Add 11,000 to both sides
[tex]9,000+11,000=2b-11,000+11,000\\9,000+11,000=2b[/tex]
Simplify by adding
[tex]20,000=2b[/tex]
Divide both sides by 2
[tex]\frac{20,000}{2}=\frac{2b}{2}\\ \\10,000=b[/tex]
Switch sides
[tex]b=10,000[/tex]
Done.
Answer:
b=10000
Step-by-step explanation:
add b on both sides
9000=-11000+2b
add -11000 on both sides
20000=2b
divide by 2 on both sides
b=10000

C. No, because retaining 10% of her salary would leave her with about $1,350.
D. Yes, because her salary will be a bit more than 1600-160=1440
Answer:
$137.50 for Liza with cents and 132 without any cents. $154 for marta wihtout cents and 165 dollars with cents. First try subtracting 137.50 from 165 and then try 154 subtract 132.
step-by-step explanation:
First you need to multiply 6 x 22 and you get your dollars! Then multiply 22 x 25 to get your cents. Also try to do it without any cents. Convert all your cents to dollars and add to your product. And multiply 7 x 22 to get the amount of dollars for marta and 50 x 22 to get the cents for marta. Also try it without cents like it could be right or wrong. Convert the cents to dollars. Lastly, subtract what marta got in 22 hours and liza got in 22 hours. Pick the closest answer.

Answer to solving for y: y = -2.
Answer for simplifying the expression: -12y - 4.
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
We are given that x = -4y and that the equation is 3x + 2y = 20.
We need to evaluate.
3x + 2y = 20
||
\/
3(-4y) + 2y = 20.
To solve for y, y = -2.
||
\/
3(-4y) + 2(-2) = -12y - 4.
Answer:
y= -2 x=8
Step-by-step explanation:
3 (-4y)+2y=20
-12y+2y=20
-10y=20
y= -2
x= -4 (-2)

2(5 - x)>8 solve for x
Answer:
x < 1
Step-by-step explanation:
To solve for x, we need to get x by itself
2(5 - x)>8
Distribute the 2
2*5 -2*x >8
10- 2x >8
Subtract 10 from both sides
10-10 -2x >8 -10
-2x > -2
Divide both sides by -2
-2x/-2> -2/-2
Since we divided by a negative number, we must flip the inequality sign
x < 1
Answer:
x < 1
Step-by-step explanation:
Given
2(5 - x) > 8 ( divide both sides by 2 )
5 - x > 4 ( subtract 5 from both sides )
- x > - 1
Multiply both sides by - 1, reversing the symbol as a result of multiplying by a negative quantity.
x < 1

Triangle ABC is congruent to Angle DEF
13x - 12 = 7x - 6
6x = 6
x = 1
Answer:
x = 1
Step-by-step explanation:
These are congruent triangles
The single line is the same length in ABC as the single line in DEF
The double line is the same length in ABC as the double line in DEF
13x-12 is the same length as 7x-6
13x-12 = 7x-6
Subtract 7x from each side
13x-12 -7x =7x-6 -7x
6x-12 =-6
Add 12 to each side
6x-12+12 = -6+12
6x = 6
Divide each side by 6
6x/6 = 6/6
x = 6/6
x = 1

When Theresa walks at a pace of 88 steps per minute, it takes her 90 minutes to walk the trail. If she alters her pace to 33 steps per minute, how long will it take her to walk the trail?
Answer: 33 minutes
Step-by-step explanation:
Hi to answer this question we have to write a proportion
Speed rate = 88 step per minute
Time = 90 minutes
So, the proportion is 88 step/min / 90 minutes
For 33 steps per minutes = 33 / x minutes
88/90 = 33/x
solving for x:
x= 33/ (88/90)
x = 33.75 = 33 minutes.

The slide at the playground has a height of 6 feet. The base
of the slide measured on the ground is 8 feet. What is the
length of the slide?
Answer:
The length of the slide is 10 feet.
Step-by-step explanation:
To find the length of the slide you have to use the formula:
a^2 + b^2 = c^2 (^2 means squared)
In this case:
a= 6 and b=8 c= unknown
6 squared (6 times 6) is 36
8 squared (8 times 8) is 64
Add these two numbers to get:
36+64=100
6^2+8^2=100
However, the length of the slide in not 100 feet. In order to find the correct length you must find the square root of 100. Which is 10.
What number times itself equals 100? 10.
The length of the slide in 10 feet.

on the first day of every month Katie gets 450 phones she repairs 10 phones every day how many phones does she have left to repair at the end of the 11 day of the month
Answer:
340 phones
Step-by-step explanation:
Make an expression
She repairs 10 phones each day, d.
Each day she repairs 10 phones, it is 10 phones off the total number (450) she has to repair, so we can subtract 10d from 450.
450-10d
We want to find how many she has left after 11 days, so we can substitute 11 in for d
450-10(11)
Multiply
450-110
340
She will still have 340 phones left to repair
Katie would have repaired 110 phones by the end of the 11th day. She started with 450 phones, so after subtracting the number of repaired phones, she has 340 phones left to repair.
Explanation:To determine the number of phones Katie has left to repair at the end of the 11th day, we need to calculate how many phones she has repaired so far. Since Katie repairs 10 phones every day, after 11 days, she will have repaired 10 phones/day * 11 days = 110 phones.
Katie starts with 450 phones at the beginning of the month. So, to find out how many are left un-repaired, you subtract the number of phones she has repaired from the starting amount.
Therefore, 450 phones - 110 phones = 340 phones are left to repair at the end of the 11th day.

|x+8|=−2
Answer:
no solution
Step-by-step explanation:
lets isolate the absolute value first:
so
|x|-8+8=-2-8
|x|=-10
since absolute value cannot be less than -10, there is no solution.
Hope this helps!
The equation |x+8|=−2 has no solution because the absolute value of a number cannot be negative.
The equation |x+8|=−2 does not have a solution because the absolute value of a number is always non-negative, and it cannot equal a negative number. The absolute value represents the distance from zero on the number line, and distance cannot be negative. Thus, the equation |x+8|=−2 is inconsistent because it implies that a non-negative quantity (the absolute value) is equal to a negative number (−2), which is not possible.
When solving equations involving absolute values such as |x| = a, if 'a' is positive, then the solutions are x = a or x = -a, because both distances a and -a from zero have the same absolute value. However, if 'a' is negative, the equation has no solution, as the absolute value cannot take on negative values. If you encounter an absolute value equation set to a negative number, you can immediately conclude that there are no solutions.
