On friday, andre biked 60 miles in 4 hours at a constant rate. on saturday, he biked at a rate that was 4 mph slower. what was his rate on saturday? a. 4 mph b. 11 mph c. 15 mph d. 16 mph

If on Saturday, he biked at a rate that was 4 mph, her rate on saturday will be 11mph. Option B is correct.

The formula for calculating unit rate is expressed as:

Unit rate = Distance/Time

Unit rate  = 60miles/4hrs

Unit rate  = 15mi/hr

This shows that Andre rate on friday is 15mi/hr

If on Saturday, he biked at a rate that was 4 mph slower, her rate on saturday will be 15-4 = 11mph

Step-by-step explanation:

You have to divide the miles / the hours = 60/4 = 15, then subtract the amount of mph he slows = 15 - 4 = 11

Answer is C

Hope this helps :)

If is correct give me brainliest pls

(x+3)(x+7)

step-by-step explanation:

so firstly, we need to isolate the y variables to be able to solve these inequalities. firstly, add 0.5x on both sides of the first inequality and subtract 1.5x on both sides of the second inequality:

now since the slope is positive for the first inequality, this means that the line going upwards belongs to the first inequality, and the line going downwards belongs to the second inequality.

next, since y ≥ in the first inequality, this means that the shaded region will be above the first inequality's line, thus shading regions a and b.

next, since y ≤ in the second inequality, this means that the shaded region is going to be below this line, thus shading regions a and c.

since both lines shade region a, this means that region a is the solution.
