Answer:
D. 240
Step-by-step explanation:
We have 20 stamps in 1 book.
We are give 12 books.
20(12) = 240
2x^2 = 72
Divide both sides by 2:
X^2 = 36
Take the square root of both sides
X = 6
Answer:
d = 100 - 25t
Step-by-step explanation:
Let's use basic logic here.
If we are 100 miles away from a place, and we've got 25 miles to go, we've already travelled 75 miles.
Since we've travelled 75 miles in 3 hours, then we travel at a rate of 75 divided by 3 = 25 miles per hour.
The distance to City A will be represented as 100 - miles already travelled. We can find how many miles have been travelled by multiplying 25 by t, the amount of hours we've spent driving.
This creates the equation d = 100 - 25t
Hope this helped!
4x - 2 = 2x + 8
*Subtract 2x from both sides*
2x - 2 = 8
*Add 2 to both sides*
2x = 10
*Divide both sides by 2*
x = 5

Answer:
see below
Step-by-step explanation:
<u>First row</u>
Fill in the given x-value and solve for y:
3(-4) +2y = -6
-12 +2y = -6
-6 +y = -3 . . . . . divide by 2
y = 3 . . . . . . . . . add 6
__
<u>Second row</u>
Fill in the given y-value and solve for x:
3x +2(0) = -6
x = -2 . . . . . . . . . divide by 3
