Answer:

12

Step-by-step explanation:

if x equals to 6 than

6+6=12

I calculated this myself, and I got the answer 3/4, but I'm trash at explaining long problems. So here is what I found to help explain it. It's not a link.

"If (p, r) lies on the line y = x + b, then

r = p + b…. (1)

If (2p, 5r) lies on the line y = 2x + b, then

5r = 2(2p) + b

or 5r = 4p + b…. (2)

Subtracting equation (1) from (2), we get

5r - r = 4p + b - p - b

4r = 3p or r/p = 3/4"

Since I don't believe in plagiarism here's the person who is a life saver at explaining things.

PS. I really did try to explain it myself, only to give myself a headache, so please don't be mad and report me. I only wanted to help.

Answer:

gradient m = 3

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the gradient and c the y- intercept )

y = 3x - 5 ← is in slope- intercept form

with gradient m = 3

Answer:

[tex]\implies\boxed{\rm \red{ Slope (m)= 3 }}[/tex]

Step-by-step explanation:

Given :-

And we need to find out the gradient of the line . Gradient of line is nothing but the slope of the line . The given equation is in slope intercept form , so we can find out the slope by comparing .

Slope Intercept form :-

[tex]\rm\implies y = mx + c [/tex]

Given equation :-

[tex]\rm\implies y = 3x - 5 [/tex]

On comparing :-

[tex]\implies\boxed{\rm \red{ Slope (m)= 3 }}[/tex]

Hence the slope of the line is 3 .

Answer:

60:90

Step-by-step explanation:

The ratio of girls (G) to boys (B) is 2 : 3.

Given the following data:

In this exercise, you're required to find the ratio of girls (G) to boys (B). In order to do this, we would divide the two values to the least.

[tex]G : B = 60 : 90[/tex]

Dividing both sides by 30, we have;

[tex]G : B = \frac{60}{30} : \frac{90}{30} \\\\G : B = 2 : 3[/tex]

Therefore, the ratio of girls (G) to boys (B) is 2 : 3.

Answer: False

=============================================================

Explanation:

The radical is one step away from being fully isolated. We would apply the rule that [tex]\frac{\sqrt{A}}{\sqrt{B}} = \sqrt{\frac{A}{B}}[/tex]

In this case,

[tex]\frac{\sqrt{x+3}}{\sqrt{x-1}} = \sqrt{\frac{x+3}{x-1}}[/tex]

Meaning that the equation

[tex]\frac{\sqrt{x+3}}{\sqrt{x-1}} =3[/tex]

is the same as

[tex]\sqrt{\frac{x+3}{x-1}} = 3[/tex]

From here, we square both sides and use algebra to isolate x.

Answer:

A = 12

Step-by-step explanation:

First you need to get the length from the perimeter, the formula is l= p/2 - w

After using the formula, you would get 6 for length. The formula for the area of a rectangle is a = lw, so you would multiply 6 and 2 which would give you 12 as your answer.

I apologize if I made any grammar mistakes or if it is unclear.

Answer:

I got area is 12 too

Step-by-step explanation:

Answer:

[tex]total \: balloons = (50 \times 7) \\ = 350 \: balloons \\ none \: yellow \: balloons = 350 - 40 \\ = 310 \: none \: yellow \: balloons[/tex]

Answer:

310

Step-by-step explanation:

The equation that we would use to solve this problem is 7 × 50 - 40 = b

(b is the number of non-yellow balloons)

Since Aaron bought 7 packs of balloons with 50 balloons in each pack, we would need to multiply 7 and 50 to find the total amount of balloons that he bought.

7 × 50 = 350.

Now we subtract 40 (the total number of yellow balloons) from 350 (the total number of balloons), to find the amount of balloons that are not yellow.

350 - 40 = 310

Answer:

625 unit²

Step-by-step explanation:

Surface area of a rectangular pyramid :

Area of base * 4(area of triangular side)

Area of base = length * width

Area of base = 15 * 15 = 225

Height of triangular side = 15

Area of triangle = 1/2 * base * height

Area of triangle = 1/2 *15 * 15 = 112.5 unit²

Surface area = 225 + 4(112.5)

Surface Area = 225 + 450

Surface Area = 625 unit²

Answer:

B.   B = 70.5° or B' = 109.5°

Step-by-step explanation:

(sin 45°)/13.5 = (sin B)/18

sin B = (18 * sin 45°)/13.5

sin B = 0.9428

B = sin^-1 0.9428

B = 70.5°

B' = 180° - 70.5°

B' = 109.5°

Answer:

5 men should be subtracted.

Step-by-step explanation:

This question is solved by proportions, using a rule of three.

As these measures(number of men needed and time) are inversely proportional, we multiply the lines instead of cross multiplication.

How many men should be working to complete the work in 32 days?

20 men - 24 days

x men - 32 days

Then

[tex]32x = 20*24[/tex]

[tex]x = \frac{20*24}{32}[/tex]

[tex]x = 15[/tex]

How many men should be subtracted?

There are 20 to complete in 24 days.

15 are needed to complete in 32 days.

20 - 15 = 5

5 men should be subtracted.
