I assume the x by 4 means multiple
-3×4×15=6-4x
-180=6-4x
-180-6=-4x
-186=-4x
x=-186/-4
x=46.5

“The 7th grade class is planning a pancake breakfast. All materials are donated except the pancake mix. Based on the given infor
ArbitrLikvidat [17]

Answer:

a) 720

b) 60$

Step-by-step explanation:

a) each person is served 3 pancakes and there are 240 people, 240 x 3 = 720.

b) Each bag of mix costs 10$ and can make 120 pancakes, but we need 720 pancakes, which means six bags of mix (since 120x6 = 720). Since each cost 10$, 10 x 6 = 60$

I have lots of math questions and I need help!

The two angles shown are vertical angles. They form when you cross two lines. They are opposite one another. Note: They don't have to be vertically up and down in relation to each other. It's possible to have them horizontally side by side like this.

So because they are vertical angles, they are congruent. This means they are equal in measure

x+90 = 4x
x+90-x = 4x-x
90 = 3x
3x = 90
3x/3 = 90/3
x = 30

Therefore the answer is choice C) The value of x is x = 30

We can check it by plugging this into the original equation above
x+90 = 4x
30+90 = 4*30
120 = 120
our answer checks out

Can you please help. Evaluate angles d and e, giving reasons for your answer. ​
garri49 [273]

Answer:

<d = 25 degrees and <e = 130 degrees

Step-by-step explanation:

We have a vertical angle, so the opposite sides of this angle are the same. This means that the angle opposite to 25 degrees also measures 25 degrees. We have one angle of the triangle. Since the triangle is isosceles, the angle d is the same as 25 degrees.

<d = 25 degrees

The interior angles of a triangle add up to 180 degrees, and we now have 2 angles, so:

<e = 180 - 25 - d

<e = 155-25

<e = 130 degrees
