1.87 is 8.5% of 22 so 8.5% of 80 is 0.085 x 80 so $6.80
If you are given y = (-3/7)x - 2 and you want it in the form Ax+By = C, then...
y = (-3/7)x-2
7*y = 7*( (-3/7)x-2) ... multiply both sides by 7
7y = -3x-14 ... distribute and multiply
7y+3x = -3x-14+3x ... add 3x to both sides
3x+7y = -14
The standard form equation is 3x+7y = -14
Y = 7.50x.....y = earnings per week , x = number of packages delivered
48 packages.....so x = 48
y = 7.50(48)
y = 360.....so if he delivers 48 packages, he earns $ 360
Each of the squares is 1 so that’s 37 plus 8 half’s which is 4 so 37 + 4 = 41
Its technically like 7/8 x 60 because 60 mins is an hour
