Mathematics Middle School

9(2x + 15) = 45
Can you help me?

Answers

Answer 1

Answer:

= -5

Step-by-step explanation:

Answer 2
First you would use distributive property and multiply the 9 and 2 (18x) then 9 and 15 (135)
Now you have 18x+135=45 so you need to get X alone by using inverse operations and subtract 135-45 (90)
18x=90 now you divide 18 and 90 and your answer is x=5

Heya!

So the key is at the top. What I mean by the Key is a=1 b=2 c=3 d=4 e=5 and f=0. You use those numbers and plug them into the associated letters in the problems below. For example, question one with the numbers in it would be, (I might be wrong on this, I apologize)

[tex] \frac{0 + 3^{2} - 2 }{0 - 3} [/tex]

You would then solve the equation, and whatever answer you get for that equation would go with the corresponding numbers and letters on the left.

So for example, if your answer to the first one for example is 7, you would type A. You would then do the same for question 2, 3, and 4, which should reveal the four letter code for you to continue :))

Answers

Answer:

For #1 the answer is $2

Step-by-step explanation:

This is because 80% of 10 is 8, so then you subtract that and get 2. For #2 the answer to item 1 is $0.8, item 2 is $3.2, item 3 is $8, item 4 is $44, and item 5 is $96

Answer/Step-by-step explanation:

During a sale, every item in a store is 80% of its regular price

[1] if a regular T-shirt is $10, what is its sale price?

80% x 10 = 8

10 - 8 = 2.

Hence if a regular T-shirt is $10, the sale price will be $2.

[2] The regular prices of five items are shown here. Find the sale price of each item.

Item 1:   1x80%=0.8

Item 2: 4x80%=3.20

Item 3: 10x80%=8

Item 4: 55x80%=44

Item 5: 120x80%=96
