Answer:

10

Step-by-step explanation:

Kinsey is 7 years less than twice Jacob's age. Let's call Jacob's age x. IF we call Jacob's age x, our equation can be 2x-7 = 13

2x - 7 = 13

2x = 20

x=10

Solve the proportion. I need to show much work so a step by step explanation would help!

Answers

Answer:

Solution: x=5

Step-by-step explanation:

Equations

This is an equation in the form of a proportion or ratio:

[tex]\displaystyle \frac{2}{x+3}=\frac{5}{4x}[/tex]

To solve it, we eliminate the denominators by multiplying by both of them.

Multiply by (x+3)(4x):

[tex]\displaystyle (x+3)(4x)\frac{2}{x+3}=(x+3)(4x)\frac{5}{4x}[/tex]

Simplify both sides:

[tex](4x)*2=(x+3)*5[/tex]

Operate:

[tex]8x=5x+15[/tex]

Simplify:

[tex]3x=15[/tex]

Solve for x:

[tex]x=15/3=5[/tex]

Solution: x=5

#2) A 12-ounce bag of marbles contains 64 marbles. Assume the relationship between weight and number of marbles is proportional. How much would you expect a bag of 160 marbles to weight (in ounces)? *​

Answers

Answer:

Step-by-step explanation:

a 12 ounce bag = 64 marbles

So first you want to find out how much each marble weighs. To do this divide 12 ounces by 64.

1 marble = [tex]\frac{12}{64} = \frac{3}{16} ounces[/tex]

To find the weight of 160 marbles, you just multiply the weight of 1 marble by 160.

160 marbles = [tex]\frac{3}{16}[/tex] ×[tex]160[/tex] = 30 ounces.

Whick equation describes the line that passes through (-3, 1) and is parallel to the line y = 4x + 1?

Answers

Answer:

y = 4x + 13

Step-by-step explanation:

First of all, if they are parallel, they must have the same slope, so the 4x is the same. all we need to do now is to change the b to make it cross the point (-3, 1). Doing so, we see that the y-intercept becomes 13. Therefore, the equation is y = 4x + 13.

What is the slope of the line that passes through the points M (-3,5) and N (1,8)

Answers

Answer:

m=3/4

Step-by-step explanation:

See the attached above.

Hope it helps :)

The slope of line passing through M (-3,5) & N (1,8) will be 3/4.

We have been given a line passing through points M (-3,5) & N (1,8) .

We have to find out what will be the slope of the line ?

What is the formula for slope of a line ?

Slope of line is given by , m = (y2-y1) / (x2-x1).

Given that line is passing through points M (x1 , y1) and N (x2,y2) or M (-3,5) & N (1,8).

here , x1 = -3 , y1 = 5 , x2= 1 . y2 = 8

The slope (m) of line will be ;

∵ m = ( y2-y1) / (x2-x1)

m = ( 8-5) / (1- (-3))

m = 3 / 4

Solve for X, and show the equation you would use to solve.

Answers

Answer:

x = 20

Step-by-step explanation:

There are both consecutive interior angles and are supplementary.

The equation should be written like this:

5x + 50 + x + 10 = 180

Step 1: Simplify both sides of the equation.

5x + 50 + x + 10 = 180

(5x+x) + (50+10) = 180 (Combine Like Terms)

6x + 60 = 180

6x + 60 = 180

Step 2: Subtract 60 from both sides.

6x + 60 − 60 = 180 − 60

6x = 120

Step 3: Divide both sides by 6.

[tex]\frac{6x}{6} = \frac{120}{6}[/tex]

x = 20
