Answer:
<span>the speed of the car after it is increased by 20%
</span>
Explanation:
We are given that the speed of the car is y miles per hour.
Now, 1.2y can be expressed as follows:
1.2y = y + 0.2 y
which is equivalent to:
1.2y = y + 20%y
Since y is the speed, based on the above, we can infer that the speed of the car increased by 20%
Hope this helps :)
The unit rate of the bicycle is 0.3 kilometers per minute.
<h3>
Linear equation</h3>
A linear equation is in the form:
y = mx + b
where y, x are variables, m is the rate of change and b is the y intercept (initial value of y).
Let y represent the km travelled by the bicycle after x minutes. From the graph using the point (0, 0) and (40, 12), hence:
Unit rate (m) = (12 - 0)/(40 - 0) = 0.3 km/min
The unit rate of the bicycle is 0.3 kilometers per minute.

Answer:
16
Step-by-step explanation:
The total profit is $93
He made a $45 profit selling hats
The question says he only sold t-shirts and hats
Since we are solving for the amount of t-shirts sold we subtract $45 from $93 and get $48 dollars earned from t-shirts
He makes $3 per t-shirt
We divide the amount per t-shirt by the total t-shirt money earned
This looks like: 48/3
We get 16 as our answer
