Answer:
x = 38
Step-by-step explanation:
The two angles in the picture are supplementary (sum of angles add up to 180°). That fact gives us the equation:
140 + (x + 12) = 180.
Subtracting 140 + 12 from both sides gives:
x = 38

Answer: A
Step-by-step explanation:
Each gallon costs 3 dollars.
8(gallons) times $3(for each gallon) = 24(dollars).
Answer:
180
Step-by-step explanation:
V= Bh
V= (9 x 4) x 5
V= 180
We are given the equation:
0.6 x + 4.8 = 7.2
In this case, the multiplication property of equality states
that whatever is multiplied on one side should also be multiplied on the other
side. Now we need to find the number that will make everything a whole number,
in this case 5. Multiply everything by 5:
5 * (0.6 x + 4.8 = 7.2)
3 x + 24 = 36
However we can see that we can still further simplify the
equation by multiplying everything by 1/3:
(1/3) * (3 x + 24 = 36)
x + 8 = 12
or
x = 4
