8 * (4 + 7) = 32 + x
8 * 11 = 32 + x
88 = 32 + x
88 - 32 = x
56 = x

Your answer would be (c) 56.

Your first step would be to solve the problem in the parentheses, ( ) because according to PEMDAS the P for parentheses indicate that you must solve that part of the equation first. 

So, 4 + 7 = 11. 

Then you would multiply 11 and 8 (11 x 8) which equals 88. 

Now you move on to the second part. 

You want both the second part and the first part to equal each other. 

So take 88 and subtract it from 32 (88 - 32) which equals your answer of 56. 

So in conclusion, 8 x (4 + 7) = 88 and 32 + 56 = 88 now both equations are equal.

Mrs. Nestler enjoys listening to classical music. She has the following audio CDs by her favorite composers in her collection: 4
ivolga24 [154]

Answer:

10.55% probability

Step-by-step explanation:

A probability is the number of desired outcomes divided by the number of total outcomes.

The order in which the CDs are chosen is not important. So we use the combinations formula to solve this question.

1 Bach CD, from a set of 4.

1 Beethoven CD, from a set of 6.

1 Brahms CD, from a set of 3.

1 Handel CD, from a set of 2.

So, D=144

4 CDs from a set of 4+6+3+2 = 15.

So, T= 1365

p= D/T= 144/1365 = 0.1055

10.55% probability that she will choose one by each composer

Answer:

4√34

Step-by-step explanation:

Let the unknown side be y

y^2 = 20^2 + 12^2

y^2 = 400 + 144

y^2 = 544

Take the square root of both side

y = √544

y = √(16x34)

y = √16 x √34

y = 4√34

Mrs.Giblin begins hiking at mile marker 25 on the Appalachian Trail and hikes 3 miles every hour. What is the slope?
Ilya [14]

Answer:

3 miles

Step-by-step explanation:

Slope is simply the change in position per unit rate. We could conclude that the steepness of the Applachian is the rate of change in position per unit time. Since the distance hiked on the Applachian is said to be 3 miles per hour, then we can conclude that the slope of the applachian is 3 miles

This is the change in miles / change in time.

Chang in miles = 3

Change in time = 1

Slope = 3/1

Slope = 3
