Simplify the algebraic expression and show how you did it -
3k - 7k + 7 - 10k

-14k+7

Step-by-step explanation:

Multiply k and 3

Multiply k and 1

The k just gets copied along.

The answer is k

k

3*k evaluates to 3k

Multiply k and 7

Multiply k and 1

The k just gets copied along.

The answer is k

k

7*k evaluates to 7k

3*k-7*k evaluates to -4k

3*k-7*k+7 evaluates to -4k+7

Multiply k and 10

Multiply k and 1

The k just gets copied along.

The answer is k

k

10*k evaluates to 10k

-4k - 10k = -14k

The answer is -14k+7

3*k-7*k+7-10*k evaluates to -14k+7

The final answer is

-14k+7

stew reads at the fastest rate of 265 words per minute.

step-by-step explanation:

it's a given that felicia reads at 260 word per minute and on connie's graph we can see that she reads 200 words per minute. since stew's table tells us that he read 795 in 3 minutes, we can divide 795 by 3 to find out how many words he reads per minute.

795/3 = 265

stew reads 265 words per minute - he reads at the fastest rate since felecia reads at 260 words per minute and connie reads at 200 words per minute.

stew (265) > felecia (260) > connie (200)
