Answer:
b=5
Step-by-step explanation:
We are going to use the basics of algebra to solve thisWe need to isolate b by itself to find the value of b.
[tex]8b + 12 = 52[/tex]
Subtract 12 from both sides
[tex]8b = 40[/tex]
[tex]b = 5[/tex]

Answer:
18.99 or 19 when rounded
Step-by-step explanation:
[tex]8 = \frac{1}{3} (a + 5) \\ 8 = \frac{1a}{3} + 1.67 \\ 3 \times 8 = \frac{1a}{3} + 1.67 \times 3 \\ 24 = a + 5.01 \\ 24 - 5.01 = a + 5.01 - 5.01 \\ 18.99 = a[/tex]
Therefore a = 18.99

A woman wishes to rent a house within 9 miles of her work. If she lives x miles from her work, her transportation cost will be cx dollars per year, while her rent will be 4c/( x + 1) dollars per year, where c is a constant taking various situational factors into account. How far should she live from work to minimize her combined expenses for rent and transportation? Use the methods outlined in this section to find the minimum.
Answer:
the woman has to live 1 mile from work to minimize the expenses
Step-by-step explanation:
Given the data in the question;
the distance within 9 miles ⇒ 0 < x > 9
Total costs Q = cx + 4c/( x + 1)
costs should be minimum ⇒ dQ/dx = 0
⇒ d/dx [ cx + 4c/( x + 1) ] = 0
⇒ ( x + 1)² = 4
take square root of both side
√[ ( x + 1)² ] = √4
x + 1 = 2
x = 2 - 1
x = 1
Therefore, the woman has to live 1 mile from work to minimize the expenses

Find the value of x so that FED ~ZYZ
need help asap
Answer:
x=7.5
Step-by-step explanation:
To show that the triangles are similar, we simply need to show that all sides are proportionate.
So, we create a proportion
[tex]\frac{FE}{ZY} =\frac{ED}{XY} = \frac{FD}{XZ}[/tex]
Then we plug in the values
[tex]\frac{6}{12} = \frac{7}{14} = \frac{2x-5}{22}[/tex]
[tex]\frac{6}{12}[/tex] and [tex]\frac{7}{14}[/tex] can be simplified to [tex]\frac{1}{2}[/tex], so that is our ratio of similarity
then we know
[tex]\frac{1}{2} = \frac{2x-5}{22}[/tex]
Now solve
1. Cross multiply
2×(2x-5) = 22
2. Distribute
4x-8 = 22
4x=30
x=7.5
There is your answer, x=7.5

Answer:
[tex]Side\ 3 = 5p^2q + 3r[/tex]
Step-by-step explanation:
Given
[tex]Perimeter = 7p^2q + 13r[/tex]
[tex]Side\ 1 = 14r[/tex]
[tex]Side\ 2 = 2p^2q - 4r[/tex]
Required
Find the length of the third side
Perimeter is calculated as thus:
[tex]Perimeter = Side\ 1 + Side\ 2 + Side\ 3[/tex]
This gives:
[tex]7p^2q + 13r = 14r + 2p^2q - 4r + Side\ 3[/tex]
Collect like terms
[tex]Side\ 3 = 7p^2q - 2p^2q + 13r - 14r + 4r[/tex]
[tex]Side\ 3 = 5p^2q + 3r[/tex]

Find the area of the figure.
7 cm
8 cm
11 cm
The area is
square centimeters.
Answer:
let's divide the figure in rectangle and triangle.
first we should find the area of triangle.
area of triangle =1/2×base×height
area of triangle=1/2×11cm×7cm
area of triangle=38.5cm²
area of rectangle =length ×width
area of rectangle =11cm×8cm
area of rectangle =88cm²
area of the figure=38.5cm²+88cm²
area of the figure=126.5cm²
Alaina evaluated 17/18+1/20 and got an answer of 18/38. Which statement is true about her answer?
1. Her answer is not correct because when you add fractions, the sum is always greater than 1.

You earn $35 for washing 5 cars. How much do you earn for washing 4 cars?
Answer:
28
Step-by-step explanation:
brainliest?
Answer:
$28
Step-by-step explanation:
Hello There!
The first thing we want to do is find how much money we earn for washing 1 car
To do so we divide 5 (amount of cars washed) by the money we made from washing those 5 cars
35/5=7
so every car we wash we make 7 dollars
now we multiply the amount of money we make washing one car by 4
4x7=28
so we would earn $28 for washing 4 cars
