Solve the equation 4-2(x+7)=3(x+5) =
Answers
Hi there!
To solve this equation, I first would like to warn you about the long answer I am about to post for you. I'll be putting in very detailed steps for you, showing you how to simplify and distribute numbers, etc. :)
Let us solve your equation step-by-step.
Step 1) Simplify both sides of the equation.
To simplify this, we will...
4 + (-2) (x) + (-2) (7) = (3) (x) + (3) (5)
4 + - 2x + - 14 = 3x + 15
(-2x) + (4 + - 14) = 3x + 15
Now, we combine Like Terms...
-2x + - 10 = 3x + 15
-2x - 10 = 3x + 15
Fwew! That was probably going to be the longest step here!
Step 2) Subtract 3x from both sides.
- 2x - 10 - 3x = 3x + 15 - 3x
- 5x - 10 = 15
Step 3) Add 10 to both sides.
- 5x - 10 + 10 = 15 + 10
- 5x = 25
Step 4) Divide both sides by -5.
-5x/-5 = 25/-5
So, our final answer is x = -5.
Hope this helps!

We need to convert all the temperature into one unit.
6 AM - 10 AM ---> 5 F = -15 C
10 AM - 2 PM ---> 6 F = -14.44 C
2 PM - 6 PM ---> 0 C.
So the total increase is 15C

x^2 + x + 2|4x^4 + 3x^3 + 0x^2 + 2x + 1
- (4x^4 + 4x^3 + 8x^2)
-x^3 - 8x^2 + 2x
- (-x^3 - x^2 - 2x)
-7x^2 + 0x + 1
- (-7x^2 - 7x - 14)
7x + 15
It is equal to 4x^2 - x - 7 + ((7x + 15)/(x^2 + x + 2)).

Answer:
252
Step-by-step explanation:
Of means multiply
84 % * 300
Change to decimal form
.84 * 300
252
Step-by-step explanation:
You need to set up a proportion. Percents always over percents, so our first fraction would be , which just means that out of 100%, we are given 84. We need to find a variable to solve for: x. We need to find the number that is 84% of 300, which means that 300 is 100%. Knowing this, it would be in the denominator, since both 100 and 300 are 100% of something. This would give us the fraction
. I like to use the cross-multiply method, which just means you multiply by a diagonal and then divide by what's left. This would give us 300 x 84 = 25,200/100 = 252. Hope this helps!
