Keith spent 2 1/2 of hours doing chores. He spent 1/4 of that time dusting. How much time did Keith spend dusting? (number model)​

Keith spent 37 and a half minutes dusting.

Step-by-step explanation:

Given that Keith spent 2 1/2 of hours doing chores, and I have spent 1/4 of that time dusting, to determine how much time did Keith spend dusting, the following calculation must be performed:

1/2 = 0.5

1/4 = 0.25

2.5 x 0.25 = X

0.625 = X

1 = 60

0.625 = X

0.625 x 60 = X

37.5 = X

Therefore, Keith spent 37 and a half minutes dusting.

answer: haha (: i’ll go see what it is

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.
