Answer:

x = 4

Step-by-step explanation:

Given

6x - 5y = 14 ← substitute y = 2 into the equation

6x - 5(2) = 14

6x - 10 = 14 ( add 10 to both sides )

6x = 24 ( divide both sides by 6 )

x = 4

Answer:

[tex]\huge\boxed{\sf x = 4}[/tex]

Step-by-step explanation:

[tex]\sf 6x-5y = 14\\\\Put \ y = 2\\\\6x - 5(2) = 14\\\\6x - 10 = 14\\\\ Adding \ 10 \ to \ both \ sides\\\\6x = 14+10\\\\6x = 24\\\\Dividing \ both \ sides \ by \ 6\\\\x = 24 / 6\\\\x = 4\\\\\rule[225]{225}{2}[/tex]

Step-by-step explanation:

Answer:

hey you didnt put the graph

Multiply the numerator together and the denominators together.

1 x 5 / 6 . 7 = 5/42

42 is not a multiple of 5 so the answer is already in the lowest term.

The answer is 5/42

sorry if im wrong

Answer:

x=5

Step-by-step explanation:

[tex]4x^2-11=89[/tex]

add 11 to both sides

[tex]4x^2=100[/tex]

Divide 4 on both sides

[tex]x^2=25[/tex]

Take the square root of both sides to eliminate the power of two from x

[tex]\sqrt{x^2} =\sqrt{25}[/tex]

Simplify

[tex]x=5[/tex]

Answer:

a.) x=10

Step-by-step explanation:

3(10)+28= 30+28

58

5(10)+52= 50+52

102

2(10)-10= 20-10

10

58+102+10= 180

Answer:

add all of the angles which equals to 180 degree

being

3x + 28 + 5x + 52 + 2x + 10=180°

which is

10x + 90 = 180

x = 180-90/10

x=11

Step-by-step explanation:

then find the value of x for each angle

Answer:

looking at the image it forms

the equation it'll make B: y= -2x -4

each dot will equal -2 and the dot is maybe one 2 but thats due to the problem of 4-2x1 so it's marked on 2 instead of four incase it throw you off of thy answer of B

Answer:

1. parallel

2. no

Step-by-step explanation:

1. The lines are parallel as they have the same slope and are at different points. Parallel lines means that the 2 lines don't ever meet. It's not the same line because they have different y-intercepts, meaning they are at different points on the graph. They're not intersecting cause like I said, they have the same slope, so they are going up and at the same angle, no way they're going to intersect. And it's not perpendicular as perpendicular lines also require the lines to intersect, which they do not.

2. Plug in (4, 1) into the equation

3x + 2y = 10

3(4) + 2(-1) = 10

12 - 2 = 10

10 = 10, so yeas for this one, now do the other

-2x + y = -7

-2(4) + (-1) = -7

-8 -1 = -7

-9 ≠ -7, so no

Answer:

C = 25 + 50h

Step-by-step explanation:

cost for zero hours is $25, so that is the y-intercept of the graph.

each hours adds a cost of $50, so that is the gradient of the graph. These two values give us our equation in slope-intercept form.

Answer:

62 degrees

Step-by-step explanation:

Since it is a straightline, the sum of both angles are 180

So, 180 - 118 = 62

Answer:

Given - Ratio of boys to girls is 3 : 1

Total 36 students

To find - No. of girls

Solution

Let the ratio be 3x and X

3x + X = 36

4x = 36

x = 36/4

x= 9

1x = 9

There are 9 girls in the class

Answer:

9 girls

Step-by-step explanation: If u write it out like this 3:1 6:2 and onwards till the two numbers add to 36 you will get the answer of 9 this should be right sorry if it isn't

Answer:

8 car's for 88$ the same thing for the 6 car's for 66$

Answer:

Laura washed 8 cars to earn $ 88

Step-by-step explanation:

Number of cars : earnings = 6 : 66

6 : 66 :: x : 88

Product of mean  = Product of extremes

 66 * x = 6 *88

        x = [tex]\frac{6*88}{66} = \frac{1*88}{11}[/tex]

       x = 8
