25(z + 2) = 125
apply distributive property
25z + 50 = 125
subtraction property of equality
25z = 75
division property of equality

Answer:
job estimate = $60.1875
Explanation:
1- labor payment:
The hourly rate is $7.5 and the job will take around 2.5 hours. This means that:
labor payment = 7.2 * 2.5 = $18.75
2- Overhead value:
The overhead value is 85%.
This means that:
its cost would be = 85% * labor payment
= 0.85 * 18.75
= $15.9375
3- Retail cost:
We are given that the retail cost is $25.5
4- getting the job estimate:
job estimate = labor payment + overhead cost + retail
job estimate = 18.75 + 15.9375 + 25.5
job estimate = $60.1875
Hope this helps :)
Sin60 = X/10√ ̅3
X=15 cm
And in triangle: (10√ ̅3)^2 = 15^2 + y^2
Y=√ ̅75= 5√ ̅3
The answer is D

Answer:
4a) 135×11/5= 297 miles
b) 216/27= 8 gallons (27miles is the distance one gallon can go)
5) 4+3+4=11
4/11 × x=160
4x=1760
x= 440
6) $4.20/14= $0.3...cereal A
$3.90/12= $0.325...cereal B
Cereal A os the better buy
7) 4×30/3= 40 presents
Hope it's all correct :-)

And also given

Now from (1) and (2), we get


Now put a in (1) we get

We can interpret that either of a or b are equal to 3 or 5.
When a=3 and b=5, we have

When a=5 and b=3, we have

Final Answer:
