You can simplify this expression with PEMDAS (parentheses, exponents, multiplication/division, addition/subtraction)

Start with the expressions in the parentheses:

4-7=-3

4+7=11

The expression now reads -2(-3)+5(11).  Now, simplify the multiplication expressions:

-2*-3=6

5*11=55

The expression is 6+55 which is 61.

Hope this helps!!

14/15 divided by 7/5
Charra [1.4K]

9514 1404 393

Answer:

  2/3

Step-by-step explanation:

There are a couple of different ways that division of fractions can be done.

1) "invert and multiply"

  \dfrac{14}{15}\div\dfrac{7}{5}=\dfrac{14}{15}\times\dfrac{5}{7}\\\\=\dfrac{14}{7}\times\dfrac{5}{15}=\boxed{\dfrac{2}{3}}

__

2) use the numerators when the denominators are the same

  \dfrac{14}{15}\div\dfrac{7}{5}=\dfrac{14}{15}\div\dfrac{21}{15}\\\\=\dfrac{14}{21}=\boxed{\dfrac{2}{3}}
