How do you solve 42 = 7/6x
Please help me and explain so I can do this on my own.

Answers

It really isn’t that hard

Answer:

I'm just trying to help so I don't know if it's correct

42 = 7/6x

you are going to multiply by 6x on both sides then you'll get and cancel the 6x on the right side of the problem

6x × 42 = 7

then you are going to divide by 42 on both sides and cancel the 42 on the left side of the equation, so you'll get 6x = 7/42

next simplify the equation

6x = 1/6

then you will try to get X by itself by dividing by 6 on both sides of the equation

so you'll get X = 1/6 ÷ 6

then you'll flip the second number and you'll get 1/6 then multiply so X will be equal to 1/36

hope you understand

Jacob sells homemade skateboard decks for a profit of $27 per deck. He is considering switching to a new type of material that will increase his profit, as expressed by the function y = 32x, where x is the number sold and y is the amount of profit.

How many more dollars will Jacob earn on each skateboard deck if he switches to the new material? Explain how you found your answer. (5 points)

Answers

Answer: I think that it is 32

Step-by-step explanation: I think this because in your equation it says (y=32x) which 32 will mean how much he is charging for each skateboard, x will be how many he sells, and y would be how much he makes from selling them. So if he sold 2 skateboards you would do 32 x 2 which equals 64 soo that would be (64=32x2) so it is 32

The tables show the numbers of white and yellow flowers Cara and Hector used in 5 different arrangements.

Cara's Flower Arrangements
White 3 6 9 12 15
Yellow 5 10 15 20 25

Hector's Flower Arrangements
White 4 8 12 16 20
Yellow 6 10 14 18 22

Part A
Are the numbers of white and yellow flowers in Cara's arrangements proportional?
Which equation relates the number of white flowers, w, to the number of yellow flowers, y?
A. Yes; y=35w
B. Yes; y=53w
C. No; y=3w+5w
D. No; y=5+3w
Part B
Are the numbers of white and yellow flowers in Hector's arrangements proportional?
Write an equation to relate the number of white flowers, h, to the number of yellow flowers, e.
A. Yes; e=32h
B. Yes; e=23h
C. No; e=h+2
D. No; e=h−2

Answers

Answer:

Step-by-step explanation:

Part A

Yes, there is a proportional relationship in Cara's. For every 5 yellow flowers, there are 3 white flowers. 5:3. I didn't see an equation that would work for the equation in the question. The equation I found on my own would be 5w/3 = y

Part B

There is no proportional relationship in Hector's. The equation would be e=h-2.

Finishing off the sentences below in the pic:

The area of each circle is exactly 2.25 pi square inches.

(As the area of a circle is: Area = pi x radius^2).
Therefore the area is: 1.5^2 x pi
Area: 2.25pi

There are TWO identical circles in the cylinder.

(Think of a cylinder and recall that a cylinder has a circle on the top and bottom of the 3-D shape, therefore a cylinder has two identical circles)

So the total area of all the circles is 4.5pi square inches.

Answers

Answer:

0.5 < x < 16.5

Step-by-step explanation:

The third side of the triangle must be longer than the difference of the other two sides:

x > (8.5 -8.0)

x > 0.5

And it must be shorter than their sum:

x < (8.5 +8.0)

x < 16.5

The third side must be in the range ...

0.5 < x < 16.5

These limits are a direct consequence of the triangle inequality, which requires the sum of the two shortest sides exceed the length of the longest side.

193 miners need to ride the elevator to the bottom of the mine. The elevator can hold 7 miners at a time. How many miners will be in the elevator on its last trip?

Answers

Answer:

Step-by-step explanation:

193/7=27 with a remainder of four.

[tex]\huge \bf༆ Answer ༄[/tex]

Here's the solution ~

There are total of 193 mimers and each time the elevator can carry 7 miners, now divide the numbers and the remainder ww get gives the number of people left at last, that is also equal to the number of miners in the last trip since they are the last group among them.

[tex] \sf193 \div 7[/tex]

On dividing, we get quotient = 27 and remainder as 4

therefore, 28th trip will be the last trip carrying 4 miners.

I hope that helps ~
