T = 25x + 30. Where 25 is the charge per hour x is # of hours and 30 is the flat fee only charged 1 time.

The triangles are similar.

X=23

I say this because you can see that the scale factor is 3 due to just visually scaling both the long and short leg from the original triangle to the dilated triangle. Dividing 39 by 3 is 13, and doing it in reverse. Adding 10 would equal 23, the initial value. So that'd be the missing value.

Answer:

Question 1: g = 6

Question 2: v = 84

Question 3: y = 60

Question 4: w = 496

Question 5: Kyle had $400 to begin with.

Step-by-step explanation:

Question 1 explanation: 12g = 72 ⇒ g = $\frac{72}{12}$ = 6

Question 2 explanation: $\frac{v}{4}$ = 21 ⇒ v = 21 * 4 = 84

Question 3 explanation: $\frac{1}{6}$ y = 10 ⇒ 6 * $\frac{1}{6}$ y = 10 * 6 ⇒ y = 60

Question 4 explanation: w + 376 = 872 ⇒ w = 872 - 376 = 496

Question 5 explanation: K - 85 = 315 ⇒ K = 315 + 85 = 400, so Kyle had $400 originally in his account.

Z x z x z x z x z what's this?

Leya [2.2K]

Z^5 is the answer because you need to add all the z’s to get a 5 for exponents

Answer:

For this question, you need you use the unitary method or proportion. If you apply these ideas to it. You should be able to do this question. Here's my working:

Step-by-step explanation:

25ounces = $3.49

**You need to find what's the price of one ounce**

So assume it like this:

1 ounce = $X

To solve for X, you figure out how did 25 became 1. In this case, it has been divided by 25. So you do the same thing on the other side: Which is $3.49 ÷25 = 0.1396 (Price per ounce for choice A)

Choice B workings:

You apply the same method, so it's 4.79 ÷ 45 = 0.1064444444444 (Price per ounce for Choice B)

So in conclusion, <em>Choice B is cheaper. </em>

<em>*</em><em>*</em><em>Please</em><em> </em><em>note</em><em> </em><em>that</em><em> </em><em>I'm</em><em> </em><em>not</em><em> </em><em>a</em><em> </em><em>maths</em><em> </em><em>teacher</em><em>,</em><em> </em><em>please</em><em> </em><em>double</em><em> </em><em>check</em><em> </em><em>your</em><em> </em><em>answer</em><em>,</em><em> </em><em>my</em><em> </em><em>answer</em><em> </em><em>might</em><em> </em><em>be</em><em> </em><em>incorrect</em><em>*</em><em>*</em>

Hope it helps!

Cheers! :)
