1st week 10 5
2nd week 20 10
3rd week 30 20
4th week 40 40

A) Amanda's method is linear because the number of minutes increased by an equal number every week.</span>
common difference is 10.
1st week 0 + 10 = 10
2nd week 10 + 10 = 20
3rd week 20 + 10 = 30
4th week 30 + 10 = 40
Billy's method is exponential:
5(2)^x
1st week 5(2⁰) = 5(1) = 5
2nd week 5(2¹) = 5(2) = 10
3rd week 5(2²) = 5(4) = 20
4th week 5(2³) = 5(8) = 40
Every Triangle adds up to 180 degrees
180 - 63 = 117 | 117 - 56 = 61 so x = 61
12y + 3 = 51 so y = 4
3 1/2
Becase if you turn them both in to inporper fractions then you can do other sh1t to find it out
