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.

Consider the graph of the linear equation 2x-5y=10. What is the x-intercept? What is the y-intercept? What is the slope?
GenaCL600 [577]
Hey there!

This linear equation is written in standard form, a form in which it's quite easy to find intercepts for one main reason. This reason revolves around zeros. When you see an x intercept, there's always a zero for the y, and when there's a y you see a zero for the x. Therefore, we can do this to get the intercepts.

For x:

2x-5(0) =10
2x = 10
x = (5,0)

For y:

2(0) -5y = 10
-5y=10
y= (0,-2)

Now, to find the slope, we can easily convert it to slope intercept form:

y = mx+b

Where m is the slope and b is he y intercept.

2x-5y=10
-5y=-2x+10
y = 2/5x-2
(notice how we divided both sides by -5)

Therefore, our slope is 2/5. Hope this helps!

Simplify expressions <br> 2=3/4x-7
Gnesinka [82]

Answer: x = 12

Step-by-step explanation:

2=\frac{3}{4}x-7

Add 7 on both sides to get rid of the 7 and isolate x.

+7+2=\frac{3}{4}x-7+7

9=\frac{3}{4}x

Now multiply both sides by \frac{4}{3} to eliminate it and isolate x.

(\frac{4}{3})(9)=(\frac{3}{4}x) (\frac{4}{3})

12=x

Proof;

2=\frac{3}{4}x-7\\2=\frac{3}{4}(12)-7\\2=9-7\\2=2

Solve the equation b over 27 equals negative 3 for b.
soldi70 [24.7K]

The solution of the equation is as follows;

  • b = -81
  • v = 7
  • x = -32

<h3>How to solve equations?</h3>

An equation is a mathematical statement that is made up of two expressions connected by an equal sign.

In other words, an equation is a formula that expresses the equality of two expressions, by connecting them with the equals sign =.

The expression can be solved as follows:

b / 27 = - 3

cross multiply

b = -3 × 27

b = - 81

42 = v + 35

subtract 35 from both sides of the equations.

42  - 35 = v + 35 - 35

v = 42 - 35

v = 7

- 128 = 4x

divide both sides of the equations by 4

4x / 4 = - 128 / 4

x = - 32
