The wall has an area of 8 * 100 = 800 square feet
So therefore 800/400 = 2 gallons are required the answer is C

Бу – 20 = 2y – 4 <br> Need explanation on how to work this problem
Lyrx [107]

Answer:

y= 4

Step-by-step explanation:

Okay so this is inverse operations.

You have to move the 2y over underneath the 6y and subtract them, you should get 4y. Your problem should now look like this. 4y-20=-4

Now you need to more the +20 over underneath the -4 and add them. Your problem should now look like this. 4y= 16

You now divide 4 into 16 which will give you 4

So y= 4

Have a good day!

Which angle measure in the triangle shown is the largest?<br><br> A.) B.) C.) D.) Not Possible
alex41 [277]
You haven't provided neither the diagram nor the options.
Therefore, I cannot provide an exact answer, however, I will try to help you with the concept.

<u>For a triangle, the measure of each angle is proportional to the length of its opposite side.</u>
<u>This means that:</u>
1- The largest angle is the angle opposite to the longest side
2- The smallest angle is the angle opposite to the shortest side

Since you are looking for the largest angle, pick the one facing the longest side

<u>Some tips and tricks:</u>
<u>1- In a right angle triangle</u>, we know that the hypotenuse is the longest side, therefore, the largest angle would be the right angle
<u>2- In an obtuse triangle</u>, the largest angle is simply the obtuse angle itself (the one whose measure is greater than 90)
<u>3- In equilateral triangle</u>, all three angles are equal

Hope this helps :)

Find an equation of the line having the given slope and containing the given point.
saul85 [17]

Answer:

y = 4x - 12

Step-by-step explanation:

The equation of a line has the following format:

y = mx + b

In which m is the slope and b is the y-intercept(value of x when y = 0).

In this question:

Slope 4, which means that m = 4.

So

y = 4x + b

Contains point (1,-8).

This means that when x = 1, y = -8. We replace this into the equation to find b. So

y = 4x + b

-8 = 4(1) + b

b = -12

So

y = 4x - 12
