Y - 4x = 7...y = 4x + 7
now sub 4x + 7 in for y in the other equation
2y + 4x = 2
2(4x + 7) + 4x = 2
8x + 14 + 4x = 2
12x = 2 - 14
12x = - 12
x = -1
y - 4x = 7
y - 4(-1) = 7
y + 4 = 7
y = 7 - 4
y = 3
solution is : (-1,3)
Answer:
$3.00
Step-by-step explanation:
Step 1. Calculate the <em>pounds of broccoli</em>.
Start with what you know: you want 32 oz of broccoli.
You know that 1 lb = 16 oz. Calculate the weight in pounds
Wt = 32 × 1/16
Wt = 2 lb
===============
Step 2. Calculate the <em>cost of the broccoli</em>.
$1.50 = 1 lb Calculate the cost
Cost = 2 × 1.50/1
Cost = $3.00
Tossing a coin would be 1/2 because a coin has two sides and it has 1 out of two sides to land on the side you want it to land on. So that answer is 1/2. The dice rolling on an even number on a six-sided number cube would be 3/6. Which if you simplify it, it would be 1/2. The answer to both of them is 1/2!
