Let's break down all the information we receive from the question.
One pair of shoes= three times as much as a scarf
One pair of shoes and one scarf= $32
We need to make an equation where 3s= pair of shoes and s=scarf. We then need to put one pair of shoes + one scarf = 32.
3s+s=32
Now add.
4s=32
You could use 4s=32 (or 32÷4=s).
Step-by-step explanation:
B) opposite sides are congruent !!!!!!
The average rate of change in h(t) between t = 1 second and t = 3 is:
(h(3) - h(1))/(3 - 1) = ((3 + 70*3 - 16*3^2) - (3 + 70*1 - 16*1^2))/2 = 6
The average rate of change in h(t) between t=1 and t=3 tells us that that average speed between these points is 6 ft/s.
Let x be the cost of dryer, y be the cost of washer
x + y =821
x-79 = y
combine 2 equation
we got
x + (x-79) = 821
2x + 79 = 821
2x = 742
x=471
The cost of dryer is $471
