Answers

Answer 1
So the conversion to meters to kilometers is 0.012 and then you multiple it by 60 because there is 60 seconds and then you multiple that anwser by 60 because there is 60 minutes in a hour then that gets you out to 43.2 km per hour

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

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.

Step-by-step explanation:

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

#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.
