Answer:

2 4/15

Step-by-step explanation:

Change both fractions to improper fractions

Multiply the denominator by the whole number then add the numinator
Keep the denominator for the final answer
So 4 2/3 = 3×4+2/3 => 14/3
2 2/5 = 2×5+2/5 =>12/5

2. Find a common multiple for both denominators and multiply to get it( numerators should be multiplied by the same number as denominators)

14/3 + 12/5 = (14×5 -12×3)/15(a common multiple)
(70-26)/15 = 34/15
Change the improper fraction(result) to a mixed fraction
To do this: divide numerator by the denominator, write result as a whole number, then put the remainder over the denominator (fraction)
34÷15 = 2 remainder 4
=2 4/15

Simplify 2x – 9y + 4x + 11y by combining like terms and then evaluate at x = -2 and y = 4.

Mashcka [7]

Step-by-step explanation:

= 2x - 9y + 4x + 11y

First of all combining like terms

= 2x + 4x - 9y + 11y

= 6x + 2y

Now putting values

= 6 (-2) + 2(4)

= - 12 + 8

= - 4
