We must solve for x. Let's simplify this equation by dividing both sides by 6:
|2x-14|=7, which is the same as 2|x-7|=7.
First, assume that x-7 is already positive, so that we don't need the absolute value operator. Then x-7=7/2. Adding 7 to both sides results in x = 21/2.
Next, find the other solution:
Assume that x-7 is negative. Then |x-7|=-(x-7). Then -(x-7) = 7,
and -x + 7 = 7. Thus, x = 0.
The solution set is {0, 21/2}.

Answer:
Palanzio's Pizza: Y= .90x+6.80
Giudo's Pizza: Y= .65x+7.30
.90x + 6.80= .65x + 7.30
.25x + 6.80= 7.30
.25x = .50
x = 2
Answer:
You'll need $2,500 in sales this week to end up with $600 in income for the week.
Step-by-step explanation:
Let s represent the dollar amount of the total sales for the week.
The commission earned on such sales is 1/5, or 0.20, of s:
Commission: 0.20s
Then the correct expression for your weekly income is:
$100 + 0.20s = $600.
Solving for s, subtract $100 from both sides. Then 0.20s = $500, and through division we get s = $2,500.
You'll need $2,500 in sales this week to end up with $600 in income for the week.
Answer:
x=-3
Step-by-step explanation:
Given: 2(x+1)=3x+5
Distributive Property: 2x+2=3x+5
Subtract 2x on both sides: 2=x+5
Subtract both sides by 5: x=-3
Therefore, x=-3
