Answer:
m=2
Step-by-step explanation:
m=y2-y1/x2-x1
m=3-1/1-0
m=2/1
m=2
So a plain pizza costs 9 dollars, and they bought two, so that's $18, and each extra topping cost one dollar, and they got three extra toppings so that's $21
Same as original, density = mass / volume, cutting the block in two pieces or any number of pieces doesn't change the density as ratio m/v remains constant.
Step-by-step explanation:
Given,
EF = 4x + 15
FG = 39
EG = 110
a/q
EF + FG = EG
after inserting the values we got,
4x + 15 + 39 = 110
→ 4x + 54 = 110
→ 4x = 110 - 54 = 56
→ x = 56/4 = 14
→ x = 14
therefore, value of x is 14.
