Step-by-step explanation:

-multiply all the sides,

-add them,

- then double the answer (or times it by 2):

1) 30 times 20 = 600

30 times 5= 150

20 times 5 =100

2) Add them:

600+150+100 = 850

then times 850 by 2

850 times 2 = 1700

Hope that helped :)

if $168.00 is the profit on a job, and this represents 8%of the contract price,what is the contract price?

Galina-37 [17]

We are told that $168.00 represents 8% of the contract price; therefore,we know that

original price *( 8/100) = $168.00

Now, writing out "original price" is a bit space-consuming; therefore, we will just rename it and say

original price = OP

Then, our equation above can be written as

$OP\times\frac{8}{100}=168$

We solve for OP (original price) by multiplying both sides by 100 and then dividing by 8. This gives us

$OP=\frac{100}{8}\times168$ $\textcolor{#FF7968}{\therefore OP=2100}\text{\textcolor{#FF7968}{.}}$

Hence, the original contract price is $2100.

72% of 25 students are intrested in math. how many are not interested in math?

saveliy_v [14]

Answer:

$7$ students are not interested in math

Step-by-step explanation:

We first need to find what is 72% of 25

Therefore:

72% of 25

=> 18

Now, since we have the number of kids who are interested in math, we must do backwards equation:

25 - 18

=> 7

Parking your car near where you work cost $.50 per hour or 4$ dollars per day. If you park for 7 hours per day, what is the leas

lawyer [7]

I think it is 17.50 because if you multiply $.50 by 7 you get $3.50. Then you multiply $3.50 by the 5 days to get $17.50

Answer: a=2/5b + 1/5c (I may have answered your question but idk if I did)

Step 1: Add -4a to both sides.

9a−2b+−4a=4a+c+−4a

5a−2b=c

Step 2: Add 2b to both sides.

5a−2b+2b=c+2b

5a=2b+c

Step 3: Divide both sides by 5.

5a/5=2b+c/5

a=2/5b+1/5c
