Add the mixed number fractions. Simplify, if possible.
Vladimir79 [104]

Answer:

8 4/15

Step-by-step explanation:

Rewriting our equation with parts separated

= 5 + 2/3 + 2 + 3/5

Solving the whole number parts

5 + 2 = 7

Solving the fraction parts

2/3 + 3/5 = ?

Find the LCD of 2/3 and 3/5 and rewrite to solve with the equivalent fractions.

LCD = 15

10/15 + 9/15 = 19/15

Simplifying the fraction part, 19/15,

19/15 = 1 4/15

Combining the whole and fraction parts

7 + 1 + 4/15 = 8 4/15

Simply this expression. Which like terms can she combine 12-4x+3
prohojiy [21]

like terms include terms that you can add/sub/mult/div - certain terms..

for example 23 and 7 are like terms, 4x and 56x are like terms....


here-> 12 and 3 are like terms so you can put them together:

12 + 3 - 4x

then you can simplify it:

15 - 4x is your answer (most simplified)
