Answer:
120 miles
Step-by-step explanation:
Step up a portion. Here, 1 cm is to 1.5 cm as 80 mi is to x mi
1/1.5 = 80/x
Now solve for x by cross multiplying
x = 120
Answer:
y=28
Step-by-step explanation:
1. As ABC is an isosceles triangle, that means that angle A is congruent to angle B, which means angle B measures 34˚.
2. The sum of the angles of a triangle add up to 180˚. So, make an equation:
A+B+C=180
As we already know A and B, plug them in:
34+34+C=180
Then solve:
C=112˚
3. As we know that C=4y, we can solve for y: 112/4=28

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
100%/x%=32.2/24.15
<span>(100/x)*x=(32.2/24.15)*x - </span>we multiply both sides of the equation by x
<span>100=1.33333333333*x - </span>we divide both sides of the equation by (1.33333333333) to get x
<span>100/1.33333333333=x </span>
<span>75=x </span>
x=75
<span>now we have: </span>
<span>24.15 is 75% of 32.2</span>
