Step one rewrite: -46-8x>22
Add 46 to both sides: -8x>68
Divide both sides by -8 to isolate x<-8.5
(remember to flip the inequality sign when multiplying or dividing by negative numbers in inequality problems)
So the correct answer is B. x < -8.5
Answer:
Her current age is 8 years old.
Step-by-step explanation:
Current age: x
"In 10 years, a child’s age will be 6 years less than triple her current age."
In 10 years: <u>x + 10</u>
6 years less than triple: <em>3x - 6</em>
<u>x + 10</u> = <em>3x - 6</em>
<em>solve.</em>
<em>16 = 2x</em>
<em>x = 8</em>
Answer:
<u><em>12</em></u>
Step-by-step explanation:
Add 50% of 16 to 16, 50% of 16 is 0.5 * 16 = 8, 16 + 8 = 24
Multiply 24 by 50%, or 0.5 to get 12
