Estimate 78 percent of 20 a. 14 b. 16 c. 19 d. 2

The correct answer is B) 16.

Step-by-step explanation:

In order to figure out the percentage of a number, turn the percentage into a decimal. In this case, the decimal would be 0.78. Then, multiply that number by 20 which should give you 15.6. Since we cant leave the answer like this, we round. 6 is greater than 5 so we round up to 16.

hope this helps:)

step-by-2step 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.
