Answer:
264
Step-by-step explanation:
First let's try the distributive property first
(-12x3)+(-12x-25)
-36+(300) Keep in mind that two negatives equal a positive
-36+300
264
There is another way to do this though
PEMDAS tells us to use what is in the parenthesis first so let's do that
-12(-22) 3-25 equals -22
264 Once again two negatives equal a positive
Your answer could be 264 or any one of these steps depending on what you need your answer to be but I'll put 264 as my "answer"
Answer:
I think C.
Step-by-step explanation:
Hey! So you’re gonna need to use the Pythagorean Theorem (a^2 + b^2 = c^2).
You’re looking for one of the legs here, so after inputting the values your equations should look like this: 6^2 + b^2 = 10^2.
Next, find what the numbers squared are: 36 + b^2 = 100.
Then, isolate the variable: b^2 = 64.
Lastly, square root both sides: √b^2 = √64.
You should find the answer is 8.

Answer: 22 gallons</h3>
Explanation:
x = max number of gallons the tank can hold
Greg's car starts off 1/3 full, so (1/3)x = x/3 number gallons is in the car.
Add on 11 more gallons to get (x/3) + 11 = x/3+33/3 = (x+33)/3
The expression (x+33)/3 represents the number of gallons he has after buying 11 gallons of gas. This is equal to (5/6)x since this represents the idea of the tank being 5/6 full
The equation we need to solve is (x+33)/3 = (5/6)x
Let's do so to get...
(x+33)/3 = (5/6)x
(x+33)/3 = (5x)/6
6(x+33) = 3*5x
6x+198 = 15x
198 = 15x-6x
198 = 9x
9x = 198
x = 198/9
x = 22
His tank can hold up to 22 gallons.
125+30% = $162.5 - 20% = $130
sorry if you get it wrong on not that good at math but I'm pretty sure this is the answer.
