Guys pls help me with C.

Answer:

8.57

Step-by-step explanation:

We can calculate the value of x using similarity ratio

11/7 = (15 + x)/(15) cross multiply expressions

105 × 7x = 165 subtract 105 from both sides

7x = 60 divide both sides by 7

x = 8.57 approximately

Answer:

  £8400

Step-by-step explanation:

The amount due after t years is ...

  A = P(1 +rt)

  A = £6000(1 + 0.10·4) = £6000·1.40

  A = £8400

Answer:

Step-by-step explanation:

3x + 6 = 8 + 3x - 2

3x + 6 = 3x + 6

Bringing like terms on one side

3x - 3x = 6 - 6

0 = 0

Answer:

no solution

Step-by-step explanation:

3(x + 2) = 8 + 3x - 2                         Explanation of steps

                                           3 times x and 3 times 2 then 8-2=6

3x + 6 = 6 + 3x

                                                               3x - 3x  = 6

6 = 6

                                                                  6 - 6 = 0

0 = 0

Answer:

X represents the amount of cups of water

Answer:

x represents the number of cups of water.

Step-by-step explanation:

The recipe calls for ¹/₄ cups of lemon juice per 1 cup of water. This means the amount of lemon juice is dependent on the amount of water. In most functions, x is the independent variable and y is the dependent variable. Since the number of cups of lemon juice is dependent on the number of cups of water, the lemon juice represents y...

...and the water represents x.

Answer:

y=23x-8

Step-by-step explanation:

Use the formula y=mx+b

y-intercept is b which is -8

the slope is m which is in this case 23

Easy peasy!

Answer:

There's no solution to this equation, when 2 equations have the same slope but different y-intercepts, they're parallel. This means they never intercept and there is NO solution and we can't solve for x.

Answer: 130

Step-by-step explanation: the only reasonable answer

Answer:it’s 15

Step-by-step explanation:because think about it if it was 12 it wouldn’t be 60% it would be 70%

Answer: With the equation being negative you would multiply it to most likely get a positive if Z is Negative. If Z is a positive but also a higher number the equation is defenitly positive. I dont know the exact answer do to the fact that you didint show the whole question.

Answer: 47 students

Step-by-step explanation:

430 students went on a trip with the majority of them going on buses.

7 students however, had to use cars.

The number of students who used buses are:

= 430 - 7

= 423 students

The number of students in each bus is:

= No. of students taking buses / no. of buses

= 423 / 9 buses

= 47 students

Answer:

45 is the answer

Step-by-step explanation:

first you have to know the sum of interior angle of that pentagon (540)

then add the all angle.

148 + x + 112 + 90 + 3x + 10 = 540.

or, 360 + 4x = 540

or, 4x = 540 - 360

or, 4x = 180

or, x = 180/4

or, x = 45

Answer:

15 students

Step-by-step explanation:

i just used multiplication

Answer:

15 students

Step-by-step explanation:

20% is 1/5

So is 3 is 1/5 you multiply 3 by 5 (since 1/5 is 3 and to find 5/5 its you need a full 5/5)

3*5 = 15

8w + 4 > 12

       -4    -4

8w > 8

/         /

8        8

w > 1

W is anything less than 1.

8w + 4 > 12

      - 4   - 4        subtract -4 to both sides.

_________

[tex]\frac{8w}{8}[/tex] > [tex]\frac{8}{8}[/tex]      divide 8 to both sides, 8's will cancel on the left side.

[tex]w[/tex] > [tex]1[/tex]

Answer:

The roots are y=2, y=-2 and y=7/4

Step-by-step explanation:

4y^3-7y^2+28=16y =0

subtract 16y from both sides

4y^3 -7y^2 - 16y +28 =0

Factor by Grouping

(4y^3 -7y^2) (-16y +28) =0

Greatest common factor

y^2(4y-7) -4(4y-7)

take y^2 and -4 as well as the repeated 4y-7

(4y-7) (-4+y^2)

change -4 to -2^2

(4y-7) (-2^2+y^2)

Similify

(4y-7).  (y-2).  (y+2)

y=7/4    y=2    y=-2
