Which sum or difference is equivalent to the following expression? 2x+3 over 4

a) x/2 + 3/4
b) x/2 - 3/4
c) 3x/4 + 3/4
d) 8x + 24

we will proceed to solve each case to determine the solution

we have the following expression

case a)

Multiply by

so

therefore

the case a) is equivalent to the expression

case b)

Multiply by

so

therefore

the case b) is not equivalent to the expression

case c)

therefore

the case c) is not equivalent to the expression

case d)

Multiply by

therefore

the case d) is not equivalent to the expression

the answer is

The equivalent expression is

the answer is 510

step-by-step explanation:

15 • 13 = 195

15 • 12 = 180

15 • 5 = 75

12 • 5 = 60

195 + 180 = 375

375 + 75 = 450

450 + 60 = 510

exa:

)

3+11

14

step-by-step explanation:

from this example, we can see that subtracting with integers is the same as adding the opposite. we can solve using a number line or by using the saying "keep, change, change" to us solve. it is important to remember that we can subtract a negative and end up with a larger number than we started with.
