61 = 3b + 7
3b + 7 = 61
3b = 61 - 7
3b = 54
b = 54/3
b = 18.
Answer:

Correct calculation:
3x³/12x^-2
= 3x³ ÷ 12x^-2
= 3x³ ÷ 1/12x²
= 3x³ × 12x²/1
= 36x^5
Tyna's calculation:
3x³/12x^-2 = x/4
We know that in this type of triangle that the hypotenuse is √2 times the length of either leg
in our case the hyp=5√2
The length of the toy tractor is 3.125ft
Data Given;
To solve this question, we need to find the length of the tractor using ratios.
<h3>What is Ratio</h3>
This is the proportion of a substance to the entire value of that substance.
