Answer:

x= 15 so the c) is right

Step-by-step explanation:

We can do it like:

3(2x + 5) = 3x + 4x

or 6x + 15 = 7x

-6x+ 6x +15 = -6x+ 7x

or 15 = x

The solution is 15

Hope you understand it.

Reika [66]

Answer: the maximum number of bundles of comic books that the box can carry is 7

Step-by-step explanation:

Let x represent the maximum number of bundles of comic books that the box can carry.

If comic books are bundled together in groups of 8, then the total number of comic books in x bundles of comic books would be 8x.

A box can hold a maximum of 60 comic books. Therefore, the inequality to find the maximum number of bundles of comic books that the box can carry is

8x ≤ 60

x ≤ 60/8

x ≤ 7.5

What should the balance be in Diane's register?<br><br> Will give BRAINLIEST
MArishka [77]

Answer:

The balance of Dianne's register should be $359.41

Step-by-step explanation:

We can begin at the ending balance on the bank statement at $578.30

Then a check is written for $219.25, so a debit

Next a deposit is made for $140.36, so a credit

Then a withdrawal is made for $140.00, so a debit

This means we can make the equation

578.30-219.25+140.36-140.00=359.41

Answer:

x=-26

Step-by-step explanation:

Subtract 45 from both sides.

-85-45=5x

Simplify  -85-45 to  -130

-130=5x

Divide both sides by 5.

-130/5=x

Simplify 130/5 to 26

-26=x
