Step-by-step explanation:
<u><em>Answer: x<-6 *The answer should be the negative sign.*</em></u>
Step-by-step explanation:
subtraction property of equality is subtracting the same number from both sides of an equation does not change the equation.
subtract 5 both sides of an equation.
5-2x-5>17-5
simplify.
-2x>12
multiply by -1 both sides of an equation.
(-2x)(-1)<12(-1)
simplify.
2x<-12
divide by 2 both sides of an equation.
2x/2<-12/2
-12/2=-6
12/2=6
6*2=12
12/6=2
x<-6
Hope this helps!
Thanks!
Have a great day!
Answer: b=5
Step-by-step explanation:

Answer:
New or current cost = 12 - 4.2 = $7.8
Step-by-step explanation:
Franco's Pizza is selling their pizzas 35% cheaper than usual. This is a discount on the normal cost. To get the amount it costs now, we will find the percentage of the discount on the original cost and subtract what we get from the original cost.
Discount = 35℅
Original cost of pizza is $12 (if a pizza normally cost $12).
So the discount in terms of dollars
= ℅ discount / 100 × normal cost of pizza
= 35 / 100 × 12 =0.35 × 12 = $4.2
New or current cost of pizza would be normal or original cost - the discount in dollars.
New or current cost = 12 - 4.2 = $7.8
