Answer:

i. A = 4 + 3t .......... 1

  B = 12 + 2t .......... 2

ii. The hours required would be 8 hours.

Step-by-step explanation:

The charges at each of the garages can be expressed as;

i. For garage A,

A = 4 + 3t .......... 1

ii. For garage B,

B = 12 + 2t .......... 2

where A is the amount charged at garage A, B is the amount charged at garage B, and t is the number of hours.

To determine the number of hours  parked that would make the cost of each garage the same.

Let:

equation 1 = equation 2

4 + 3t = 12 + 2t

collect like terms

3t - 2t = 12 - 4

t = 8

The hours that would make the cost of each garage the same is 8 hours.

Answer:

Proportion:  1/3=3/x

Step-by-step explanation:

The "1/3" proportion is telling us how the scale measurement relates to the real measurement.

The "3/x" describes the length of side B.

Now it is easy to figure out the answer! :D

2. 87.76

3. 3

Step-by-step explanation:

1.

x * 0.05 = 136

136/0.05 = 2720

2.

86/x = 0.98

86/0.98 = 87.76

Answer:

The point-slope form of an equation of the line is:

[tex]y-9 = 5(x+2)[/tex]

Step-by-step explanation:

Given

Slope m = 5

Point (-2, 9)

Point slope form of an equation of a line:

Point slope form of an equation of a line is defined as

[tex]y-y_1=m\left(x-x_1\right)[/tex]

where

In our case,

substituting the values m = 5 and the point (x₁, y₁) = (-2, 9) in the point-slope form of the line equation

[tex]y-y_1=m\left(x-x_1\right)[/tex]

[tex]y - 9 = 5 (x - (-2)[/tex]

[tex]y-9 = 5(x+2)[/tex]

Therefore, the point-slope form of an equation of the line is:

[tex]y-9 = 5(x+2)[/tex]

Answer:

D. 81 sq. ft.

Step-by-step explanation:

We know x, y, and z's lengths. Those are 3, 12, and 9 respectively.

I first imagined a 12 by 9 rectangle and then figured about the area of the shaded part.

The 12 by 9 rectangle is 108 sq ft, But there is a empty part on the top left. That would be a 9 ft by 6 ft triangle.

The area of a triangle can be figured out with this formula: A = bh/2 Substitute b and h for 9 and 6 respectively.

A = (9 * 6)/2

A = 54/2

A = 27 sq. ft.

Now, subtract 27 from 108 to get the area of the shaded part.

108 - 27

81 sq. ft.

The area of the tile being used is 81 sq. ft.

[tex] \frac{24}{13} = \frac{x}{39} [/tex]

We move 39 to multiply 24/13.

[tex] \frac{24}{13} (39) = x \\ 24(3) = x \\ 72 = x[/tex]

Substitute x = 72 in the equation.

[tex] \frac{24}{13} = \frac{72}{39} \\ \frac{24}{13} = \frac{24}{13} [/tex]

The equation is true for x = 72.

[tex] \large \boxed {x = 72}[/tex]

Answer:

783

Step-by-step explanation:

87×9=783

:) have a good day

Answer:

783

Step-by-step explanation:

you can split the 87 into two parts, multipy 80*9, which is 720, and then 7x9, which is 63. Add them up and you got 783.

Answer:

3 for the first question and 12 for the second question

Step-by-step explanation:

For the first question 6^2 = 12 × X and 36 = 12x divide both sides by 12 and x = 3

For the second question x^2 = 18 × 8

x^2 = 144

x = 12

Answer:

13,000

Step-by-step explanation:

Answer:

divide all terms by same numeral

Step-by-step explanation:

4x-6y+16

2x-3y+8

Answer:

The answer is C.   16(0.5x-0.75y+2)

Step-by-step explanation:

I just got it correct on e d g e n u i t y!!!!!!!!!!!!!!!!!

Also the math the do it is this. Take the first answer for example. because of the parentheses you are going to take the number out side of the parentheses and multiply it by the numbers that are in the parentheses. So lets apply this.  

1st Example... 16(0.5x-4y+32)  

16 * 0.5x (When using a calculator just put in 16*0.5) The answer is 8 add on the x so it is 8x. 16*4y= 64y 16*32= 512. Then when you add symbols in you turn out with an answer for 1 that should look like this... 8x-64y+512 That is not equivalent to 8x-12y+32. So this is not the correct answer. (Because it isn't equivalent)

2nd Example... You can narrow down the search and make it easier if you do this... There is still a 32 in it and multiplying 32 and 16 will always equal 512 so you know it is not the second answer.

3rd Example... The third example Is correct because 1 all the other answers aren't lol. and 2 because the math steps are correct I will show you.  16(0.5x-0.75y+2)   16*0.5x=8x   16*0.75y=12y (looking pretty good!!) 16*2= 32!!

So in an equation it looks like this... 8x-12y+32 Thus leading us to the answer that the third option(Option C. ) Is correct!!

4th Example... This can not be correct because you are looking for an answer with 12y and 4y*16 will always equal 64y so it cannot be this answer.

KEY= * is the times symbol!!

Also if you want to right great answers like this put in an extra little bit of effort to learn the material and you will be golden in no time at all!!!

Have a great day!!!!

Also can I have a five star a thank you and a Brainliest it would really make my day! UwU

Answer:

3f-9g+7

Step-by-step explanation:

Given:

The expression is

[tex]10+(2\times 3)^2:4\times \dfrac{1}{2}[/tex]

To find:

The value of the expression.

Solution:

We have,

[tex]10+(2\times 3)^2:4\times \dfrac{1}{2}[/tex]

It can be written as

[tex]=\dfrac{10+(2\times 3)^2}{4\times \dfrac{1}{2}}[/tex]

[tex]=\dfrac{10+(6)^2}{2}[/tex]

[tex]=\dfrac{10+36}{2}[/tex]

[tex]=\dfrac{46}{2}[/tex]

[tex]=23[/tex]

Therefore, the value of the given expression is 23.
