What is the value of 9(4x - 4), when x=5?
Do all multiplication first, then solve the problem from left to right.

ILL GIVE BRAINLIET

Answers

I believe by asking you to do all multiplication first they are asking you to demonstrate the distributive property, this means we can distribute the 9 through the parenthesis by multiplying it by each part inside the parenthesis, this gives us:

36x - 36

now we can substitute 5 in for x to get:

36(5) -36

180-36

Penny is making a model of a Ferris wheel that is 60 feet tall. The model is 15 inches tall. Penny is also
making a model of the sky needle ride that is 100 feet tall using the same scale. How tall is the model of
the sky needle?

Answers

The model of the sky needle will be 20 inches tall as the scale factor is 4.
Since the Ferris wheel model is in feet and inches, bring both measurements to inches, then divide the total height of the Ferris wheel by the height of the model, then you multiply the height of the sky needle ride by the quotient of the height of the Ferris wheel and the model of the Ferris wheel to get 7 inches

Hayley has $155 in savings, and her brother Hank has $230. Hayley is saving $10 each week, and her brother is spending $15 each week. After how many weeks will their savings accounts have the same amount of money in them?

What is the best way to set up this word problem to solve?


15x+155=230+10x
15 x plus 155 is equal to 230 plus 10 x

155−15x=10x+230
155 minus 15 x is equal to 10 x plus 230

155+10x=230−15x
155 plus 10 x is equal to 230 minus 15 x

155−10x=230+15x

Answer:

The Correct Answer is The 3rd one, Or C

Step-by-step explanation:

It will take 3 weeks

If its right mark me brainliest if its wrong report me.

Answer:

$155+$10x=$230-$15x

Step-by-step explanation:

weeks= x

$155+$10x=$230-$15x is the correct answer because hayley currently has $155 in her saving and you have to add the 10 dollars she saves each week which is 10x. On the other hand, her brother has $230 and spends $15 dollars every week so that is 15x.
