Marie rode her bike 325 miles in 20 hours last month. Tamara rode her bike 255 miles in 15 hours last month. Are these speeds proportional? Explain. 1. No; Marie's rate is 16.25 m/h and Tamara's rate is 17 m/h
2. Yes; to find both speed rates, you need to divide the distance by the time.
3. No; Marie's distance and time are greater than Tamara's distance and time.
4. Yes; Marie's and Tamara's rates are almost the same.

infinitely many solutions

step-by-step explanation:

we have been given the equation;

2(2x + 3) = -4 + 2(2x + 5)

we need to determine the value of x.

2(2x + 3), we expand this expression to obtain 4x + 6

similarly 2(2x + 5) will become 4x + 10

now we have;

4x + 6 = -4 + 4x + 10

4x + 6 = 4x + 10 - 4

4x + 6 = 4x + 6

the expression on the left hand side is identical to the one on the right hand side. therefore, we are looking at just a single straight line whose equation is;

y = 4x + 6

consequently, we shall have infinitely many solutions
