The product is the result of multiplying, and whatever number is multiplied by 3 is the amount of times you add 3 to the answer.
Example:
3x7= 3+3+3+3+3+3+3=21
Answer:
Therefore a car travelled 288 miles in 4 hours.
Step-by-step explanation:
Given:
The car travels at the rate of 72 mph
Equation is given by
To Find:
How far a car travels in 4 hours = ?
Solution:
Distance covered is equal to the product of speed and time.
We have
.............Given
where,
d = distance
t= time
So at t = 4 hours
Therefore a car travelled 288 miles in 4 hours.
The equivalent expressions are 3(6x - 3) = 72 and 18x - 9 = 72
<h3>Equations and expressions</h3>
Given the equation below as shown;
3/5(30x - 15) = 72
Expand
3/5(30x) - 3/5(15) = 72
90x/5 - 15/5 = 72
3(6x - 3) = 72
Expand
18x - 9 = 72
Hence the equivalent expressions are 3(6x - 3) = 72 and 18x - 9 = 72
