Answer:
x = (-5, 21)Step-by-step explanation:
|x - 8| < 131 .
x - 8 < 13x < 8 + 13x < 212.
x - 8 > -13x > 8 - 13x > -5Combined answer
-5 < x < 21x = (-5, 21)The new post office has an area that is 6.5 times the area of the old post office. Let p represent the area of the old post office. Write an expression to represent the area of the new post office?
Answer:
[tex]Area = 6.5p[/tex]
Step-by-step explanation:
Given
[tex]Area\ of\ Old = p[/tex]
[tex]Area\ of\ New = 6.5 * Area\ of\ Old[/tex]
Required
Write an expression for the area of new post office
From the question, we have the following:
[tex]Area\ of\ Old = p[/tex]
and
[tex]Area\ of\ New = 6.5 * Area\ of\ Old[/tex]
Substitute p for Area of Old in the second equation
[tex]Area\ of\ New = 6.5 * p[/tex]
[tex]Area\ of\ New = 6.5 p[/tex]
Hence, the expression is:
[tex]Area = 6.5p[/tex]
The sum of two numbers is 60. The greater number is 6 more than the smaller number. Which equation can be used to solve for the smaller number?
1) x + (x + 6) = 60
2) x- (x + 6) = 60
3) x(x + 6) = 60
04) x(x-6) = 60
Answer:
1) x + (x + 6) = 60Step-by-step explanation:
Let the numbers be x and y
x + y = 60y = x + 6Then, substituting y:
x + (x + 6) = 60Correct option is 1)
After Thanksgiving, Fernando had 3/8 of a pumpkin pie left. Later that night, 1 point
Fernando ate 2/3 of the remaining pie. How much of the pumpkin pie did
Fernando eat?*
3/8 of the pie
9/16 of the pie
1/4 of the pie
06/24 of the pie
Answer:
(C) 1/4 of the pie.
Step-by-step explanation:
Given that Fernando had 3/8 of a pumpkin pie left.
So, the remaining pie= 3/8 of a pie.
As Fernando ate 2/3 of the remaining pie, so,
the portion of a pie that Fernando ate = 2/3 x 3/8 of a pie = 1/4 of a pie.
So, Fernando ate 1/4 of a pie.
Hence, option (C) is correct.

Find three consecutive odd integers such that when the third is subtracted from five times
the sum of the first and second, the result is 798 more than the first.
9514 1404 393
Answer:
99, 101, 103
Step-by-step explanation:
Let x represent the smallest. Then the sum of the first two is (x+x+2) and the third is x+4. The problem statement tells us the relation ...
5(2x +2) -(x +4) = x +798
10x +10 -x -4 = x +798
8x = 792
x = 99
The integers are 99, 101, 103.
__
Check
5(99 +101) -103 = 99 +798
897 = 897 . . . . answer checks OK
Ricky is solving a multiplication problem where both terms include decimal values. The first term has 4 digits after the decimal. The second term has 5 digits after the decimal. The product will have how many digits after the decimal?
Answer:
9 digits
Step-by-step explanation:
when doing multiplication with decimals the amount of digits after the decimal in the final product will be the sum of the amounts of digits after the decimal in the two numbers being multiplied together
For example, If you were to multiply 6.789 by 10.321 the answer would be 70.069269. There are six digits after the decimal because the numbers being multiplied each have three digits after their decimals

A person and a building cast a shadow at the same time of day. The person is 5.8 feet tall in case the shadow of 3.2 feet. The building cast a shadow of 28 feet.
Find the height of the building.
round your answer to the nearest 10th of a foot.
Answer:
Height of the building = 50.8 ft
Step-by-step explanation:
A person and a building are casting the shadows at the same time of the day.
Triangles formed by the person and his shadow and the building and its shadow will be similar.
Therefore, corresponding sides of the similar triangles will be proportional.
[tex]\frac{x}{28}=\frac{5.8}{3.2}[/tex]
x = [tex]\frac{5.8\times 28}{3.2}[/tex]
x = 50.75
x ≈ 50.8 ft

An airport shuttle service charges $15 plus $1.15 per mile. An equation is written as y=mx+b, where y is the cost for x miles.
Answer: See explanation
Step-by-step explanation:
You didn't really say what you need to calculate but let me try to help out.
From the question, we are informed that an airport shuttle service charges $15 plus $1.15 per mile and that an equation is written as y=mx+b, where y is the cost for x miles.
The equation can be expressed as:
y = 15 + 1.15x
where,
15 = y intercept and this is the initial fixed cost
1.15 = slope and this is the cost per mile
x = number of miles

Which of the following equations is equivalent to 4(a + 2) – 2(a – 8) = 24?
Answer:
Step-by-step explanation:
4a + 8 - 2a + 16 = 24
Solving like terms
2a + 24 = 24
2a = 24 - 24
2a = 0
Answer: 2a+24=24
Step-by-step explanation: How to get the CORRECT answer:
4(a+2)-2(a-8)
4a + 8 - 2 (a-8)
4a + 8 - 2a + 16
2a + 8 + 16
2a + 24
Final Answer: 2a + 24

What is the inverse function F(x)=-1/2(x+3)?
The inverse of the function f(x) is
[tex]f^{-1}[/tex] (x) = 2x - 3
What is a function?A function is a relationship between inputs where each input is related to exactly one output.
Example:
f(x) = 2x + 1
f(1) = 2 + 1 = 3
f(2) = 2 x 2 + 1 = 4 + 1 = 5
The outputs of the functions are 3 and 5
The inputs of the function are 1 and 2.
We have,
f(x) = 1/2 (x + 3)
Put f(x) = y
y = 1/2 (x + 3)
Replace y and x.
x = 1/2 (y + 3)
Find y.
2x = y + 3
y = 2x - 3
This means,
[tex]f^{-1}[/tex] (x) = 2x - 3
Thus,
The inverse of f(x) is 2x - 3.

Olivia needs 54 ticks for every 3 lollipops she eats. Complete the table using equivalent ratios. Lollipops
Answer:
36:2
90:5
Step-by-step explanation:
I got 2 because if we figure out how many licks she gets for every 1 lollipop that will help find the other numbers. When we divide 54 by 3 we get 18. For every 1 lollipop she lickes 18 times. To figure out how many lollipops for 36 I added 18 plus 18 which gives me 36. I added it twice or multiples by 2. Since I multiplied by 2 the lollipops will be 2. Since we know the rate of change which is 18. We know that for 3 lollipops the person will lick 54 times. I added 54 plus 18 two times which gave me 90. So for 90 licks the person will have 5 lollipops. I hope this helps.
