A hiking trail is 7 miles long. Han hikes 1/2 of the trail and then stops for water. Jada hikes 2/3 of the trail then stops for water. a) How many did Han hike before stopping for water? b) How many did Jada hike before stopping for water?

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

the answer is 844

step-by-step explanation:

it is 844 because if you add 836.50 + 7.5 you will get 844
