Answer:
$13.64
Step-by-step explanation:
The backpack is originally priced at $22. During the sale, the price would be 38% off which means you pay 62% of the original price. We can find this by multiplying by the percent 62 (converted into a decimal).
22(0.62)=13.64
The sale price at the sale is $13.64.
Answer:
-10
Step-by-step explanation:
Let x = number

Subtract x from each side
x-10-x = 2x-x
-10 = x
The number is -10
Answer:
49.5
Step-by-step explanation:
given:
x² + 12x = 11
perfect square:
a² + 2ab + b²
a² = x² ⇒ x * x
2ab = 12x ⇒ 2(6)x
b² = 6² ⇒ 36
x² + 12x + 36 = 11 + 36
(x+6)(x+6) = 47
Both sides must be added with 36.
