What the value of x help me

Answer:

[tex]Girls = 319[/tex]

Step-by-step explanation:

Given

[tex]Boys: Girls = 15:11[/tex]

Required

Find Girls, when Boys = 435

Substitute 435 for Boys

[tex]435: Girls = 15:11[/tex]

Express as fraction

[tex]\frac{Girls}{435} = \frac{11}{15}[/tex]

Multiply through by 435

[tex]435 * \frac{Girls}{435} = \frac{11}{15}* 435[/tex]

[tex]Girls = \frac{11}{15}* 435[/tex]

[tex]Girls = \frac{11* 435}{15}[/tex]

[tex]Girls = \frac{4785}{15}[/tex]

[tex]Girls = 319[/tex]

Answer:

they can finish

[tex] \frac{1}{15} + \frac{1}{12} \\ [/tex]

in one hour

[tex] \frac{4 + 5}{60} \\ \frac{9}{60} [/tex]

in 6 hours they can finish

[tex] \frac{9}{60} \times 6 \\ \frac{54}{60} [/tex]

so the left work

[tex] \frac{60 - 54}{60} [/tex]

[tex] \frac{6}{60} [/tex]

they can perform

[tex] \frac{3}{60} work in60 \: minutes \div 3[/tex]

so the can perform

[tex] \frac{6}{60} work \: in \: 20minutes \times 2[/tex]

the take 6 hours and 40 minutes

Answer:

A. $448

B. $679

C. $421

D. $877

Step 1: multiply each original amount by .08 (because that's the percent amount)

For example: 415 x 0.08 = 33.2

Step 2: Add that product to the original amount.

For example: 415 + 33.2 = 448.2

Step 3: Don't forget to round to nearest dollar.

For example: 448.2 --> 448

Answer:

Step-by-step explanation:

C, not extremely sure though

Answer:

f(x) = -4x-1

f(7) = -(4)(7)-1

f(7) = -29

g(x) = 4x^2 - x

g(-4) = 4(-4)^2 - (-4)

g(-4) = 4(16) + 4

g(-4) = 64 + 4

g(-4) = 68

Answer:

6) x = 6.75

7) x = 27.29

Step-by-step explanation:

cross multiply

6)_______________________

9/16 = x/12

16x = 108

divide by 16

x = 6.75

7)_______________________

7/11 = 18/x + 1

7x + 7 = 198

     -7       -7

7x = 191

divide by 7

x = 27.29

Answer:

[tex]\Huge\boxed{-8}[/tex]

Step-by-step explanation:

Hello there!

When given two ordered pairs we can use the slope formula to solve for the slope

[tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex]

where m = slope

All we have to do is plug in the y and x values into the formula and calculate the slope

[tex]m=\frac{1-9}{7-6} \\1-9=-8\\7-6=1\\\frac{-8}{1} =-8\\m=-8[/tex]

So we can conclude that the slope of the line that passes through the points (6,9) and (7,1) is -8

Answer:

b = 3

Step-by-step explanation:

15 - b = 12

-15        -15

-b = -3

b = 3

Hope this helped! Have a nice day! Plz mark as brainliest!!!

Answer:

b=3

Step-by-step explanation:

15-b=12

-b=12-15

-b=-3 divide both sides by -1

b=3

Answer:

the answer is c

Step-by-step explanation:

your equation is to solve the circle so A could not be the answer B/c it can't be 9.the answer is c or d. But d can't give you 3 if you solve it. so the answer is C

Answer:

C. [tex]| v -21 | \leq 0.15[/tex]

Step-by-step explanation:

Because the volume is either 0.15 more or 0.15 less than 21 ounces. [tex]| v - 21 |[/tex] indicate the difference between the volume and 21 and it has to be less than 0.15. Therefore answer C.

Answer:

x=4 z=117

Step-by-step explanation:

Answer:

x = 4, z = 117

Step-by-step explanation:

14x + 7 and 63 are vertically opposite angles and are congruent, then

14x + 7 = 63 ( subtract 7 from both sides )

14x = 56 ( divide both sides by 14 )

x = 4

z and 63 are adjacent angles and are supplementary, then

z + 63 =180 ( subtract 63 from both sides )

z = 117

Answer:

Step-by-step explanation:

MKN and MCN are supplementary angles.

Supplementary angles sum to 180°:

Answer:

B

Step-by-step explanation:

B because the number line goes from negative 6, -2, and x must be greater than negative 6 but less than or equal to 2

Answer:

6.70h <= 155

Step-by-step explanation:

1. Define a variable.

Let h = number of hours

2. Write the inequality.

We know that he earns $6.70 an hour. We also know that he needs at least $155, which means he needs greater than or equal to 155. Therefore, 6.70h <= 155.

Answer:

The answer is z = 34.

Step-by-step explanation:

1) Simplify 2 + 8 - z to 10 - z.

[tex]10 - z = - 24[/tex]

2) Subtract 10 from both sides.

[tex] - z = - 24 - 10[/tex]

3) Simplify - 24 - 10 to -34.

[tex] - z = - 34[/tex]

4) Multiply both sides by -1.

[tex]z = 34[/tex]

Therefor, the answer is z = 34.

Answer:

x = 5

Step-by-step explanation:

(10/3)/5 = (x+1)/9

(10/3)9 = 5(x+1)

90/3 = 5x + 5

30 = 5x + 5

25 = 5x

x = 5
