Karolina [17]

To start off, Chang has already saved $45. $125 - $45 = $80. Therefore, he owes $80. $80 ÷ 7 = 11.4285714286, so he needs to work 12 full hours to pay for his trip.

How many quart are 8/1/4 gallons

Westkost [7]

Given:

Consider the given gallons are $8\dfrac{1}{4}$ gallons.

To find:

The number of quarts in $8\dfrac{1}{4}$ gallons.

Solution:

We know that,

1 gallons = 4 quarts

Using this conversion, we get

$8\dfrac{1}{4}\text{ gallons}=4\times 8\dfrac{1}{4}\text{ quarts}$

$8\dfrac{1}{4}\text{ gallons}=4\times \dfrac{32+1}{4}\text{ quarts}$

$8\dfrac{1}{4}\text{ gallons}=4\times \dfrac{33}{4}\text{ quarts}$

$8\dfrac{1}{4}\text{ gallons}=33\text{ quarts}$

Therefore, there are 33 quarts in $8\dfrac{1}{4}$ gallons.

What’s the value of X ???!!!!

Alexus [3.1K]

Answer:

Step-by-step explanation:

So since triangle jkl and wyz are similar angles j and w must equal each other, angles k and y must equal each other, and angles l and z are equal. So to find x just set 4x-13 equal to 71

4x-13=71

add 13 to both sides to cancel the -13 from the left

4x=84

and divide both sides by 4 to cancel the 4 on the left

x=21

Find the slope of a line perpendicular to <br><br> Y= -x -1

ad-work [718]

<h2>Greetings!</h2>

Answer:

The slope is 1.

Step-by-step explanation:

First, we must find the slope of the current equation.

This is the number in front of the x.

Seeing as this is -x, or -1x, the slope of this line is -1

When finding the slope of a line perpendicular, you need to find the $\frac{-1}{slope}$

So, in this case it is:

$\frac{-1}{-1}$

The minuses cancel out, leaving with 1 over 1 or 1/

So the slope of the line perpendicular is 1!
