Answer:
48 pizzas
60 pizzas
72 pizzas
Step-by-step explanation:
So pretty straight forward
So first you divide the amount of cheese by 3
so for the first one you have 18 pounds of cheese
Now 18/3=6
Now using that quotient (6) you multiply that by 8
6*8=48
So 18 pounds of cheese is 48 pizzas
Same thing with the others, even with the decimal one
Answer:
b) -18(2x -3y + 5)
d) 18(-2x + 3y - 5)
e) -2(18x - 27y + 45)
Step-by-step explanation:
a) -9( 4x - 6y - 10) = -36x + 54y + 90 not equal
b) -18(2x - 3y + 5) = -36x + 54y - 90 equal
c) -6(6x + 9y - 15) = -36x - 54y + 90 not equal
d) 18(-2x + 3y - 5) = -36x + 54y - 90 equal
e) -2(18x - 27y + 45) = -36x + 54y - 90 equal
f) 2(-18x + 54y - 90) = -36x + 108y - 180 not equal
Answer:
x = 14.3
Step-by-step explanation:
To find one of the sides, we can use the pythagorean theorem:
a² + b² = c²
a² = c² - b²
a = √c² -b²
a = √(20)² -( 14)²
a = 14.3
