Three ratios that are equal to 40/50, 75/100, and 21/18 are 4/5, 3/4, and 7/6. The question is essentially asking you to simplify fractions. For example, 8/10 can also be represented as the ratio 8:10. This fraction can be simplified to 4/5, and the ratio 4:5 is the same as the ratio 8:10.
The answer is 18 and not 22
Reason: Abby started at 4y (which is the offset) So you do is 22-4 and it gives 18. So abby climbed 18 feet
Answer:
40
Step-by-step explanation:
y = 50 + .4 x 40
y = 30 + .9 x 40
y = 66 for both equations
Answer:
the answer is
Step-by-step explanation:
x=1/2y+5---i
4x+3y=-20 ----ii
putting value of x in eqn Ii
4×(1/2×y+5)+3y=-20
2y+5+3y=-20
5y+5=-20
5y=-20-5
5y=-25
y=-25/5
y=-5
putting value in eqn I
x=1/2×-5+5
x=-5/2+5
x=5/2
154 +36 = 180
7 tikes 22 = 156
6 times 6 = 36
