y = Sara's age
Nick is 8 years older than Sara, therefore
y = x - 8
A graph of y versus x is shown below.
Answer:
x=4
Step-by-step explanation:
First of all, the sides of the smaller triangle are multiplied by 5 to make it bigger. So, multiply 4 by 5 which gives you 20. So, 20= 3x+8.
Now that we have our equation, we need to isolate the variable.
Subtract 8 from both sides.
20= 3x+8
- 8 -8
Divide both sides by 3.
<u>12</u>= <u>3x</u>
