Step-by-step explanation:
142 ÷ 2 = 71
D. ( 100÷2) + (40÷2) + (2÷2)
50 + 20 + 1
71
Answer:
(4,-20)
Step-by-step explanation:
midpoint ((x1+x2)/2, (y1+y2)/2)
Let S be (x,y(
(0+x)/2=2, solve for x, x=4
(4+y)/2=-8, solve for y, y=-20
B.
remember it's rise over run.
Set up the ratio as fractions
(5/8) cup red / (2/5) cup yellow = r amount of red / 1 cup yellow
Then cross multiply the numbers and set up as a equation like this
(5/8) × 1 = (2/5) × r
(5/8) = (2/5)r
Multiply both sides of the equation by (5/2) to get rid of the fraction and solve for r
(5/2) × (5/8) = (2/5)r × <span>(5/2)
25/16 = r
Reduce down to 5/4 or change to a mixed number
1 and 1/4 cups = r</span>
