Answer:

see explanation

Step-by-step explanation:

12.

- 27 = 9(6 + y)

There are 2 possible approaches to solving this equation

Approach 1

divide both sides by 9

- 3 = 6 + y ( subtract 6 from both sides )

- 9 = y ⇒ y = - 9

Approach 2

distribute the parenthesis on the right side of the equation

- 27 = 54 + 9y ( subtract 54 from both sides )

- 81 = 9y ( divide both sides by 9 )

- 9 = y ⇒ y = - 9

13.

- 2(- 2x + 6) = 2 + 3x ( distribute parenthesis on left side )

4x - 12 = 2 + 3x ( subtract 3x from both sides )

x - 12 = 2 ( add 12 to both sides )

x = 14

In 1911, the first year of the Indianapolis 500 auto race, the winning car had an average speed of 109.416 feet per second. What
Elena-2011 [213]

Answer:

74.6018 Miles per hour

Step-by-step explanation:

Step 1: How many seconds are in an hour? There are 60 seconds in a minute and 60 minutes in an hour, so there are 60*60 = 3600 seconds in an hour.

Step 2: How many feet are in a mile? There are 5280 feet in a mile.

Step 3: To convert feet per second to miles per hour, first multiply by 3600, then divide by 5280. The fraction 3600/5280 reduces to 15/22.

To convert feet per second to miles per hour, multiply by 15/22.

So: 109.416 feet/second * (15/22) = 74.6018 miles/hour

Two sides of an acute triangle are 8 and 15. how many possible lengths are there for the third side, if it is a positive integer
Misha Larkins [42]
In an accute triangle the 3 angles are less than 90°.

The minimum lenght of the third side is if the other two sides form the lowest possible angle (close to 0 degrees), in which case the length approximates to zero, so if the number is an integer, the minimum length of the fhird side is 1.

The maximum length of the third side is if it is close to the hypotenuse of a right triangle with legs 8 and 15 =>

hypotenuse^2 = 15^2 + 8^2 = 289 => hypotenuse =17. So, the lenght of the third side must be less than 17.

So, the possible lengths of the third side are 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, and 16.

Coach Rivas can spend up to $750 on 30 swimsuits for the swim team. The inequality shown can be used to find the maximum amount
777dan777 [17]

Answer:

$0 < p ≤ $25

Step-by-step explanation:

We know that coach Rivas can spend up to $750 on 30 swimsuits.

This means that the maximum cost that the coach can afford to pay is $750, then if the cost for the 30 swimsuits is C, we have the inequality:

C ≤ $750

Now, if each swimsuit costs p, then 30 of them costs 30 times p, then the cost of the swimsuits is:

C = 30*p

Then we have the inequality:

30*p ≤ $750.

To find the possible values of p, we just need to isolate p in one side of the inequality.

So we can divide both sides by 30 to get:

(30*p)/30 ≤ $750/30

p ≤ $25

And we also should add the restriction:

$0 < p ≤ $25

Because a swimsuit can not cost 0 dollars or less than that.

Then the inequality that represents the possible values of p is:

$0 < p ≤ $25
