d) by Calculating the amount of miles it would take John to go to school plus the amount of miles it would take Sara to go to school. Then add the sum of the amount of miles it took for both to go to school.

Step-by-step explanation:

a) explanation:

$a^{2} +b^2=c^2$

$16^2+30^2=c^2$

$256 + 900 = c^2$

$c^2=1156$

$\sqrt{1156}=34mi$

b) explanation:

$a^{2} +b^2=c^2$

$6^2+8^2=c^2$

$36+64=c^2$

$c^2=100$

$\sqrt{100} =10mi$

c) explanation: we already have all the data from John's house to Sara's House.

John's House to Sara's House = John's House to School + Sara's House to School.

Sara's House to School (Question #1) = 34mi

John's House to School (Question #2) = 10mi

34(mi) + 10(mi) = 44(mi)

Answer: Number one would be 3x+2y+-14 and x+y=-4, second one is x=-3, y=7

Step-by-step explanation:

The first one is solved by inputting the x and y in each one and finding which one comes out true, the second on is solved by substitution. to find x you would subtract x in the first equation and make it y=4-x then input that equation in the y in the second equation.

The formula S=3F-24 is used to calculate shoe size,S, from food length,F(in inches).which equation could be used to calculate fo

sp2606 [1]

Solving
S = 3F - 24
for F gives
S + 24 = 3F
(S + 24)/3 = F

The best choice is the last one:
F = (S + 24)/3
