Answer:
A
Step-by-step explanation:
Given
- k - (- 8k + 7) ← distribute parenthesis by - 1
= - k + 8k - 7 ← collect like terms
= 7k - 7 → A
So...
You have 16 quarters. 5 dimes. And 1 nickel. (Half dollars are 2 quarters put together)
I hope this helps!
You would need to shade 1.5 boxes or 6 pieces to have shaded 25% of the shape.
In total, there are 6 boxes. There are 4 pieces per box. In total, there are 24 pieces.
6/4 = 1.5
24/4 = 6
You would need to shade 1.5 boxes, which is equal to 6 pieces or triangles.
lets take the certain number and call it 'x'
take 2.5 of the number = 2.5x
when we add 1.75 - 2.5x + 1.75
and divide by 0.8 - (2.5x+ 1.75)/0.8
the answer is 37.5
lets construct an equation with this information
(2.5x + 1.75)/0.8 = 37.5
2.5x + 1.75 = 37.5* 0.8
2.5x = 30 - 1.75
2.5x = 28.25
x = 28.25/2.5
x = 11.3
