Plug in what we know:
Find the cube root of both sides:
![\sf~a=\sqrt[3]{2744}](https://tex.z-dn.net/?f=%5Csf~a%3D%5Csqrt%5B3%5D%7B2744%7D)
Simplify:
You have already done half of it. Now substitute for x1 = 4 and y = 5
y - 5 = 6/7(x - 4)
Multiply everything by 7 to remove fractions
7y - 35 = 6(x - 4)
7y - 35 = 6x - 24
-6x + 7y = -24 + 35
-6x + 7y = 11
Some people prefer a positive number in front of x so multiply by -1
6x - 7y = -11
You can check the answer by testing it works for both of the original points
6x4 - 7x5 = 24 - 35 = -11 true
6x-3 - 7x-1 = -18 - -7 = -11 true
Answer:
Step-by-step explanation:
400/700 = 4/7
salt: 4/7 × 14 g = 8 g
yeast: 4/7 × 7 g = 4 g
oil: 4/7 × 35 mL = 20 mL
water: 4/7 × 420 mL = 240 mL
Answer:
80
Step-by-step explanation:
So, let's say the total number of pizzas is x
If 15% of x, the total, is 12, then x * 0.15 must = 12
Use this to make an equation
12 = 0.15x
Divide both sides by 0.15 to get x on its own
12 / 0.15 = x0.15 / 0.15
80 = x
80 pizzas were sold
Answer:
(8 x 8) x 6 or 6(8 x 8)
