Step-by-step explanation:

In the provided screenshot, the value of r is 2.5.

We would replace 'r' with 2.5 and then make 's' the subject of the equation.

[tex]2r + 3s = 14\\\rule{150}{0.5}\\2(2.5) + 3s = 14 \leftarrow \text {This would go in the first blank.}\\\\5 + 3s = 14 \leftarrow \text {This would go in the second blank.}\\\\3s + 5 = 14\\\\3s + 5 - 5 = 14 - 5\\\\3s = 9 \leftarrow \text {This would go in the third blank.}\\\\\frac{3s=9}{3}\\\\\boxed{s = 3} \leftarrow \text {This would go in the fourth blank.}[/tex]

There are four lines hidden in the graph. Here are their equations: y=-2x+9 y=-2x-6 y=3x-1 and y=1/2x-1 Capture all of the lines by entering ordered pairs for points on the lines. Use no more than three zaps.

Answers

Linear equations are equations that have constant slopes

The ordered pairs of the equations are:

(0,9), (0,-6), (0,-1) and (0,-1)

How to determine the lines

The equations are given as:

y=-2x+9

y=-2x-6

y=3x-1

y=1/2x-1

Set x to 0, to calculate the corresponding y-value in all the equations

[tex]y=-2(0)+9 =9[/tex]

[tex]y=-2(0)-6 = -6[/tex]

[tex]y=3(0)-1 =-1[/tex]

[tex]y=1/2(0)-1 = -1[/tex]

So, the ordered pairs of the equations are:

(0,9), (0,-6), (0,-1) and (0,-1)

What is the longest line segment that can be drawn in a right rectangular prism that is 15 cm long,
11 cm wide, and 7 cm tall?

Answers

Assuming you want to find the length of the longest line segment, you would have to first determine where the longest line segment is.

If you can't do this straight away, then it'd be good to draw a diagram as I shown below, to visualise.

From there, you apply pythagora's theorem to the dimensions of the rectangular prism to find the length of the longest line segment.

I have attached the solution in a photo, including some explanation. Hope it helps :)

don't just use a calculator pls

Answers

Answer:

So this is an inequality and can be easily solved if its opposite number is done with both the sides. There are some inequality rules which are:

1. when absolute values removed; the number in the oppostite side becomes negative and if negative then positive. And the signs are changed to its opposite sign. Like greater than to less than or vise versa.

2. When both the sides are divided or multiplied by a negative number the signs are changed.

An angle measures eleven more than four times a number. Its compliment is
two more than three times the number. What is the measure of each angle?

Answers

Answer:

35 and 55 degrees

Step-by-step explanation:

Let's use n for the number

Angle 1 = 4n+11

Angle 2 = 3n+2

Since it states that these angles are complimentary, they add up to 90 degrees

So we can write an equation using what is given.

Angle 1 + Angle 2 = 90

4n+11+3n+2 = 90

Combine like terms

7n+13 = 90

Subtract 13 from each side

7n = 77

n = 11

Now we plug eleven in for n and solve for the measure of each angle.

Angle 1 = 4(11)+11

Angle 1 = 44+11

Angle 1 = 55

Angle 2 = 3(11)+2

Angle 2 = 33+2

Angle 2 = 35

pounds. These cars made up 10% of all the cars.
How many cars were there in the race?

Answers

Answer:

Angela, a proportion is two equal ratios, kinda like 3/4 = 6/8.

 

If we call the number of cars c, then our proportion is 3/10 = c/100.

 

Cross multiplying, we get 10c = 300.

 

Dividing both sides by 10, c = 30.

Answer:

30 cars

Step-by-step explanation:

3 cars made up 10% of all the cars x:

3 ⇒ 10%x ⇒ 100%x = 3*100/10 = 30
