A.)list the 4 steps outlined in the lesson on solving equations. (1 points)

b.)solve each equation and show all work (3 points each)

1.) 5x + 7 = 3x + 21

2.) 3x - 2(5 - x) = -3(x - 10) + 3x

3.) 5(x + 1) = 3(2x + 3) + 5

For this case we must solve the following equations:

We subtract 3x on both sides of the equation:

We subtract 7 on both sides of the equation:

We divide between 2 on both sides of the equation:

The second equation is:

We apply distributive property to the terms of parentheses:

We add common terms:

We add 10 to both sides of the equation:

We divide between 5 on both sides of the equation:

Third equation:

We apply distributive property to the terms within parentheses:

We add similar terms:

We subtract 6x on both sides of the equation:

We subtract 5 on both sides of the equation:

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)
