Answer:
C) 20, 4
Step-by-step explanation:
X = 5y
2x + 5y = 60
substitute in 5y for x: 2(5y) + 5y = 60
10y + 5y = 60
15y = 60
y = 4
x = 5y
x = 5(4) = 20
Answer:
1. 3/4 + 3/4 + 3/4 +3/4
2. 0.75 * 4
Step-by-step explanation:
1. add 3/4 four times
3/4 + 3/4 + 3/4 +3/4
2. You can turn 3/4 into a decimal. 3/4 =0.75
0.75 * 4
From x equals five to nine, the y value changes as follows
+10,+2,+1,+3
Assuming that "average" implies the mean, the sum of all four values is 15. Then divide 15 by the four values added = 15/4 = 3 3/4 or 3.75
X divided by 30 because it is going down by 30 percent.. :)
