Naoya read a book cover to cover in a single session, at a rate of 55 pages per hour. After 4 hours, he had 350 pages left to read. Let y represent the number of pages to read after x hours

y = 570 - 55x

Step-by-step explanation:

y = T - 55x

350 = T - 55(4)

T = 350 + 220

T = 570

y = 570 - 55x

We can write the expression as: y = 570 - 55x

At the time, there were 350 pages left so we can add to find the total amount of pages.

350 + 220 = 570 pages

Naoya can read 55 pages per hour. This can be represented by 55x, where "x" is the amount of hours he reads for.

Best of Luck!

step-by-step explanation:

always plug in x. in this case, x equals 4.

i'm going to first solve 4(2+3x)

1) 4(2+3(4)) use pemdas to solve.

i'm going to multiply whats in the parenthesis first, so 3 times 4=12.

2)4 (2+12) i'm then going to multiply 4 by both numbers in the parenthesis (because multiplying comes before adding)

4 times 2= 8.   4 times 12= 48

4) (8+48)= 56 (answer)

i'm then going to solve 8+12x and plug in 4 for x.

1) 8 +12(4)

multiplying comes before adding, so i'm gonna multiply 12 and 4.

12 times 4= 48.

2) 8+48=56

both equal the same!

17.08

correct me if i am wrong.
