Solve for x:

2x + 30 = (30/10) * 5(2x + 3) + 87

Answers

x = -9.375
im not sure if i interpreted the times symbol right

step-by-step explanation:
2x + 30 = (30/10) • 5(2x + 3) + 87
2x + 30 = 3 • 10x + 15 + 87
2x + 30 = 105 • 10x
-2x -2x
30 = 105 • 8x

The volume of a right rectangular prism is 70 7/8 cubic feet and its base is a square with a side length of 4 1/2 feet. what is the height?

Answers

Answer:

7/2 feet

Step-by-step explanation:

Volume of Right Rectangular Prism: V = w * h * l

You are given the volume, and the base (which would include l and w)- and are told to find h.

70 7/8 cubic feet = 4 1/2 feet * h * 4 1/2 feet (simplify the right side)

70 7/8 cubic feet = 81/4 feet squared * h (divide both sides by 81/4)

7/2 feet = h

The height will be 7/2

Answers

Answer:

E(last one)

Step-by-step explanation:

We dont know much for this, so lets just go over the basics of what we know:

Most of the numbers are between 2-7.

Very very few of the numbers are 9<

Now there is the number 8, which is not spoken of, so we can just conclude that it doesnt matter how many we see in a list of numbers.

Now, looking at each, we should be able to figure out which one is correct by which set of numbers has the lowest amount of numbers between 9<.

In the first case, 3 of the numbers are 9<(9, 9, and 11)

In the second case, 7 of the numbers are 9<(14, 11, 12, 9, 10, 9, 11)

In the third case, 3 of the numbers are 9<(14, 9, 11)

In the fourth case, 5 of the numbers are 9<(12, 14, 10, 11, 11)

Finally, in the fifth case, 2 of the numbers are 9<(9, 10)

So it must be the fifth answer, since it has the least with numbers 9<.

Hope this helps!

Love your profile picture by the way :D

Note that if it is multiply choice, the first, second, and fifth answer would work.

If it is single choice, then it will definatly be the fifth answer.

I think it is D. (If it’s multiple choice then let me know.)

what is the value of y ?

Answers

Answer:

Step-by-step explanation:

First find the total of the entire straight line. We know that a straight line is 180 degrees.

Since we already have 2 given numbers, add them.

51+31=82

Since we already have 82 degrees, subtract it with 180.

180-82=98.

So, y = 98

A coach jogs 1.8 miles on Monday, 1.3 miles on Tuesday, and 1.2 miles on Wednesday. If the coach’s friend jogs twice as far as the coach, how many miles does the coach’s friend jog, written as a decimal?

Answers

So his friend runs 3.6 on m and 2.6 on t and 2.4 on w and the decimal is 0.036 and 0.026 and 0.04

Since it’s double,
1.8 x 2 = 3.6
1.3 x 2 = 2.6
1.2 x 2 = 2.4
3.6 + 2.6 + 2.4 = 8.6
