Answer:

a=3

Step-by-step explanation:

3a-4=5

put the 4 on the same side as the 5 and switch it from - to +

Ex.  3a=5+4

now add the 5 and the 4

Ex.   3a=9

now isolate the variable (thats the letter) by dividing 3a by 3, then divide the 9 by 3 simultaneously

The first thing we know is that all the answers equal 99, so we cannot cross any answer off, however, what we want to know is what answer (after distribution) looks like 36 + 63...

Does 33+66 look like 36+63?

NO

B.) 9(4 + 7) > 36 + 63

Does 36+63 look like 36+63?

YES

C.) 11(4 + 5) > 44 + 55

Does 44+55 look like 36+63?

NO

D.) 3(15 + 18) > 45 + 54

Does 45+54 look like 36+63?

Add 3/7 + 8/9 . Simplify the answer and write as a mixed number
Fudgin [204]
You will get both of the fractions over the same denominator, so it will be 27/63 and 56/63, then you will add the two numerators, so it will then come out to 83/63, and you will then simplify that by subtracting 63 from 83, and will get 1  20/63
