It has to be either the first option or the last option because when u see variables it will usually be all of the letters so if your looking for a quick answer its probably the last option

There were 90 runners just start a race in the first half of the race 1/3 of them dropped out in the second half of the race 1/5

Eva8 [605]

Answer:

6 runners finished the race

Step-by-step explanation:

it starts with 90 runners. then 1/3 of them dropped out in the second half of the race, that means you do 90 divided by 3

90 ÷ 3 = 30

Then, 1/5 of the runners remained.

That means you do 30 divided by 5

30÷ 5= 6

so the answer is 6 remaining runners finished the race.

Complementary angles add up to 90°
and supplementary angles add up to 180°

Add the two angles together
82+98=180
So the measure of these two angles are supplementary

Given the system of equations, what is the solution?

pychu [463]

Answer is C. By solving x-y=-5 to x=-5+y and converting 2x + y = -1 into 2x + x + 5 = -1 the answer becomes -2 =x. By plugging that into 2 (-2) + y = -1, the answer is y=3. So your answer is C

Write an expression to represent each of the following sketches. Then give the value of each sketch.

zysi [14]

The sketches are illustrations of inequalities

The first sketch is: $-2 \le x \le 5$ .
The second sketch is: $3 \ge x \ge -4$

Sketch A

In sketch A, we have the following observations:

The arrow faces left (this implies less than)
The dots on -2 and -5 are closed dots (this implies less than or equal to).

Hence, the inequality is:

$-2 \le x \le 5$

Sketch B

In sketch B, we have the following observations:

The arrow faces right (this implies greater than)
The dots on -4 and 3 are closed dots (this implies greater than or equal to).

Hence, the inequality is:

$3 \ge x \ge -4$
