Answer:

-2

Step-by-step explanation:

1. Rewrite the equation:

2(3x - 3) = -18

2. Use the distributive property:

2(3x - 3) = -18 ---> 6x - 6 = -18

3. Add 6 to both sides:

6x - 6 = -18 ---> 6x = -12

4. Divide both sides by 6:

6x = -12 ---> x = -2

Now we know our answer is -2, let's make sure it's correct:

2(3x - 3) = -18

2(3(-2) - 3) = -18

2(-6 - 3) = -18

-12 - 6 = -18

-18 = -18

This tells us our answer is true!

Hope this helps :D

The sum of 3 times a number and 7, divided by 5, is 17 written as an equation

Anestetic [448]

Equation is: $\frac{3x+7}{5}=15$

and Value of x is $x=68/3\\$

Step-by-step explanation:

We need to write an equation of:

The sum of 3 times a number and 7, divided by 5, is 17

Let the number = x

So, equation will be:

$\frac{3x+7}{5}=15$

We can solve the equation to find the value of x.

$\frac{3x+7}{5}=15\\3x+7=15*5\\3x+7=75\\3x=75-7\\3x=68\\x=68/3\\$

So, Equation is: $\frac{3x+7}{5}=15$

and Value of x is $x=68/3\\$

Which choice answer is it?

Debora [2.8K]

Your answer would be option (1) -3x² - 18x + 19.

To find this we need to substitute in the G and F expressions into G - 3F and see what the outcome is, as this will give us the answer.

First I’m going to multiply the F expression, 2x² + 6x - 5, by 3:

3 × (2x² + 6x - 5) = 3(2x²) + 3(6x) - 3(5) = 6x² + 18x - 15.

Now we need to subtract this expression from G, which is 3x² + 4, which I will do by term:

3x² - 6x² = -3x²

0x - 18x = -18x

4 - -15 = 19

So therefore overall your answer is -3x² - 18x + 19.

I hope this helps! Let me know if you have any questions :)
