to simplify it, we need to combine like terms. 8 and 15 are like, and 5x and 2x are like. so we rearrange it: 8+15-5x-2x

and now we simplify: 23-7x

First of all we will collect like terms by saying 8+15-5x-2x

Threfore the final answer is 22-7x

Find the value of f(5) for the function f(m) = 1 - 4(m/2) *

Sloan [31]

Answer:

f(m) = -9

Step-by-step explanation:

We replace m with 5 in the function.

f(m) = 1 - 4(m/2) becomes f(5) = 1 - 4(5/2)

then we solve the numbers in the parenthesis first

= 1 - 4 (5/2)

= 1 - 4 (2.5)

= 1 - 10

= -9

You need at least $100 to go to a BTS concert. You have $27 and your allowance is $10

REY [17]

Count by 10s after 27 so continue with 37, 47, 57 until you get past at least 100, which should be 8 times. Therefore it would take 8 weeks of allowance to reach $107

. 7 prizes are to be distributed between 3 people with a guarantee that each person gets at least one prize. Find the number of

ANEK [815]

Answer:

Total number of ways to distribute the prize = 2187

$3^{7}= 2187$

Step-by-step explanation:

Given:

Number of prizes = 7

Number of peoples = 3

We need to find the total number of ways to distribute the prize.

Solution:

From the above statement, 7 prizes are to be distributed between 3 people, wherein each person gets at least one prize.

Each prize is to be distributed among three persons. When the first prize is to be awarded, one of the three is chosen to win the prize. When the second prize is to be awarded, there are again three choices.

So, total number of distribution of the prizes is given as:

$3\times 3 \times 3\times 3\times 3\times 3\times 3=3^{7}$

$3^{7}= 2187$

Therefore, total number of ways to distribute the prizes = 2187

Given (x – 7)2 = 36, select the values of x.

Gre4nikov [31]

Answer:

x = 13 and x = 1

Step-by-step explanation:

(x-7)² = 36

simplify left side of equation

x² - 14x + 49 = 36

Our object now is to get every thing on the left side of the equal sign so we can factor. To do this, we subtract 36 from both sides

x² - 14x + 13 = 0

we then factor the left side of the equation

( x - 1 ) ( x - 13 ) = 0

we then set factors equal to 0 and solve both factors for x

x - 1 = 0

add 1 to both sides

x = 1

x - 13 = 0

add 13 to both sides

x = 13

The values of x are x = 13 and x = 1
