First, distribute the left side. You should get 4x-8-2x+4=4x-8. Then, get all the xs on one side.
4x-2x-4x-8+4=-8
Then, put the numbers on one side.
4x-2x-4x=-8+8-4
Then, add it up.
-2x=-4
Then, solve for x.
(-2x)/(-2)=(-4)/(-2)
x=2
Hope that helps!
Answer:
60 percent
Step-by-step explanation:
so 50 is half of 100,right? so that means you can just multiply everything by 2 to make it easier. so then there are 100 students and 40 play basket ball. so that means 40 percent play basketball and that only leaves 60 remaining :)
The answer is 60 because it can be divided by all three numbers. Next time you come across problems such as these, I suggest you start by looking at the number that makes sense logically. For instance, numbers that have 5 as a factor must end with 0 or 5, narrowing the options down to 65 and 60. Since 65 is an odd number, the answer can only be 60.
The answer fam is<span>Part A: Company A: y=30x+13 Company B: y=28x+15 </span>
<span>X: number of mattresses </span>
<span>Y: total cost </span>
<span>Part B: </span>
<span>Company A: 30(4)+13= 133 Company B: 28(4)+15= 127 </span>
<span>Company B cost less than Company A does when you purchase 4 mattresses </span>
<span>Part C: </span>
<span>Company A: 30(7)+13= 223 </span>
<span>Company B: 28(7)+15= 211 </span>
<span>You save $12 by using the services of Company B instead of Company A to clean 7 mattresses</span>
14/15 should be the answer :) if you can find a way to simplify it I would and I’m sorry if I’m wrong
