PLEASE HELP = simplify 3/4(-10+2/5)
solniwko [45]
There are many ways to do this depending on the property you have to use:

If you use the distributive property, you need to distribute 3/4 to -10 and 2/5. Distribute means you will multiply it so your resulting equation will be this:

\frac{-30}{4}  -  \frac{6}{20}

Before you can add, you need to first make them like terms because you cannot add unlike fractions. Get the LCD and form your new equation:

\frac{-150+6}{20}

Now you can just add them together to get:
\frac{-144}{20}

and then simplify your fraction:
\frac{-36}{5} or - \frac{36}{5} 

The whole fraction becomes negative because when you divide integers and of them is negative, the final answer will be negative.

The product of a number and -8 gives eight times the sum of that number and 36. Find that number
Viefleur [7K]

Answer:

-18

Step-by-step explanation:

Let x be our number. First we have to write our equation.

The product of a number and -8 is represented as -8x (-8 multiplied by x). Remember that 'product' signifies multiplication.

The result is eight times the sum of x and 36. This is represented as 8(x + 36). We add x and 36 first because 8 has been multiplied by the sum of those two numbers.

So our equation is:

-8x = 8(x + 36)

We can now solve for x. First, expand the bracket.

-8x = 8x + 288

Next, subtract 8x from both sides. This will give us only one term containing x, which will make it easier to solve.

-8x - 8x = 8x + 288 - 8x

-16x = 288

Divide both sides by -16

x = -18
