Answer:
50+ 20x= y
25+ 40x= y
Explanation:
For Billy and Susie, the starting values are $50 and $25. You simply add that to the money saved per week ($20 and $40).
x= number of weeks
The slope is: y = 3x + 6

Answer:
= -120a³b²c²
Step-by-step explanation:
10ac * 6ab * -2abc
10*6*-2 = -120
ac * ab * abc = a*a*a *b*b*c*c = a³b²c²
then:
10ac * 6ab * -2abc = -120* a³b²c²
= -120a³b²c²
Answer: 10
Step-by-step explanation:
If the long side of the fence is 20 the other side is 20 which means if the short side is 10 the other would be 10 making the total to 60 meters.
The amount each boy receives from the R2100 is R420, R700 and R980 respectively
<h3>How to find ratio</h3>
Total amount = R2100
Ratio = 3 : 5 : 7
Total ratio = 3 + 5 + 7
= 15
First boy = 3/15 × 2100
= 0.2 × 2100
= R420
Second boy = 5/15 × 2100
= 0.33333333333333 × 2100
= R700
Third boy = 7/15 × 2100
= 0.46666666666666 × 2100
= R980
