True or false..How do I know if it's no solution

Misha Larkins [42]

Answer:

False

Step-by-step explanation:

If (8,9) is a solution, you will be able to substitute 8 for x, and 9 for y.

(-2 x 8) + (4 x 9) = -20?

-2 x 8 = -16

4 x 9 = 36

-16 + 36 = 20

So, (8,9) is not a solution to the system.

Answer:

$\frac{-5}{28}$

Step-by-step explanation:

Given:

$\frac{-1}{5} * (\frac{3}{4} + \frac{1}{7})$

Required:

Solve

Solution:

$\frac{-1}{5} * (\frac{3}{4} + \frac{1}{7})$

Apply distributive property by multiplying each reaction in the box by -⅕

$(\frac{-1}{5} * \frac{3}{4}) + (\frac{-1}{5} * \frac{1}{7})$

$\frac{-3}{20} + \frac{-1}{35}$

Add together. Common denominator is 140. Therefore:

$\frac{-21 + (-4)}{140}$

$\frac{-25}{140}$

Simplify further

$\frac{-5}{28}$

What is 3 / 1 - 1/2

Alona [7]

Answer:

Step-by-step explanation:

3 / 1 - 1/2 = 3 / 1/2

when dividing by singular fractions (1/3 1/6 1/29 whatever) just multiply by the denominator so 3 ÷ 1/2 = 6
