-5+7q+ -5q+ -9q please help

vekshin1

For this case we must simplify the following expression

$-5 + 7q + (- 5q) + (- 9q)$

We know that, by definition:

$+ * - = -$

So, rewriting the expression we have:

$-5 + 7q-5q-9q =$

We add similar terms taking into account that:

Equal signs are added and the same sign is placed.

Different signs are subtracted and the major's sign is placed:

$-5 + 2q-9q =\\-5-7q$

Answer:

$-5-7q$

I need help on how to solve the problem and the correct answer :)

lakkis [162]

This is a system of linear equations. First, you can add the two equations together to eliminate the y so that you can solve for x:

-5x + -7x = 0 + -96

-12x = -96

x = 8

Use x to solve for y:

-5 * 8 + 8y = 0

Add 40 to both sides and divide by 8:

y = 5

So, x = 8 and y = 5.

The answer is miles. I'll use decimals in my explanation.
23.25 divided by 0.2 equals 116.25
116.25 multiplied by 65 equals 7556.25
7556.25 divided by 5280 equals 1.43110795455
Rounded to the nearest tenth that's 1.4
Hope it helped.
