Algebratic expressions the product of 4 and a number is increased by 7

product means multiply

increased by means add

 so product of 4 and a number would be 4n

 than add 7

 so you have 4n+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)

you can't solve x because it is 2 linear equation and you only have one equation
