A number plus -3 is 8

a number (x) plus (+) -3 (-3) is (=) 8 (8).

Step-by-step explanation:

x+(-3)=8

x=11

A number: since we don't know what the exact number is we can represent that number with a variable. Let's use x...

x + (-3) = 8

You can also write this as...

x - 3 = 8

They both mean the same thing :)

When you solve...

x - 3 = 8

add 3 on both sides...

x = 11

Your answers are...

x + (-3) = 8

x = 11

Hope this helps :)

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)

set each factor equal to 0

4x-3 = 0

2x-1 = 0

solve for x.

4x-3=0

4x=3

x= 3/4

solve for x. 

2x-1= 0

2x= 1

x= 1/2

your answer should be 1/2 is less than or equal to x and 3/4 is greater than or equal to x
