Tallulah biked 84 miles at a rate of 10.5 miles per hour. Determine now many more
A.0.125 hours
B. 8 hours
C. 84.5 hours
D. 882 hours

b. 8 hours

Step-by-step explanation:

to figure out how it took, we must divide the total distance by the speed rating.

84 / 10.5 = 8

so the answer is b. 8 hours

hope it helps :D

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
