Answer: 21

Step-by-step explanation: We can use the method: Keep, Change, Flip.

1. Keep 7.

If you want 7 to become a fraction, you can do it like this: [tex]\frac{7}{1}[/tex]

2. Change division to multiplication.

It's very simple. Just change the sign.

3. Flip [tex]\frac{1}{3}[/tex].

It's like converting it into a improper fraction. [tex]\frac{1}{3}[/tex] is now [tex]\frac{3}{1}[/tex].

Now we can solve!

[tex]\frac{7\times3}{1\times1} =21/1[/tex]

Therefore, your answer is 21/1 or just 21.

Can someone please tell me what to do step by step Pleaseee

Answers

Answer:

z = -1

Explanation:

-3z - (3z - 2) = 4(z + 3)

Expand -3z - (3z - 2): -6z + 2

Expand 4(z + 3): 4z + 12

-6z + 2 = 4z + 12

Subtract 2 from both sides

-6z + 2 - 2 = 4z + 12 - 2

Simplify

-6z = 4z + 10

Subtract 4z from both sides

-6z - 4z = 4z + 10 - 4z

Simplify

-10z = 10

Divide both sides by -10

-10z / -10 = 10 / -10

Simplify

z = -1

BRAINLIEST INCLUDED!!!! Elena went to a sporting goods store that was having a sale. She bought a tennis racket and 3 cans of tennis balls. The tennis racket normally costs $43. All tennis rackets are marked down 15%. One can of tennis balls normally costs $4. The tennis balls are not marked down. The sales tax rate is 8.5% How much will she pay for everything, including tax?

Answers

Answer:

She will pay $52.68, including taxes

Step-by-step explanation:

One can of tennis ball is $4 and there are no discount on it. Elena bought 3 cans, so:

can = 3 x 4 = 12

One tennis racket is $43 but it has a discount of 15%:

discount = 0.15 x 43 = 6.45

total racket = 43 - 6.45 = 36.55

Elena will have to pay:

pay = 12 + 36.55 = 48.55

She will also have to pay taxes, which are 8.5% over the price she paid:

pay + tax = 48.55 x 0.085 = 4.13

total to pay = 48.55 + 4.13 = 52.68

Buying 3 can of tennins ball and one racket, Elena paid $52.68, including taxes.
