Answer:
there is a 0.02 or 2% difference
Answer:
x=-21
Step-by-step explanation:
x-7=2x+14
-7=x+14
-21=x
First, you need to isolate the x in the first equation.
-x + 5y = 1
Subtract 5y from both sides, leaving you with the following equation:
-x = 1-5y
Because you are trying to solve for positive x and not negative x, you need to make x positive. Therefore you divide both sides by -1. In Algebra, when 1 is the coefficient of the variable, it is not shown, but it is still there. The new equation will be the following: x = 5y-1
Now you just need to substitute the x within the second equation for the x equation we just solved for.
Therefore, the right answer will be 2(5y-1)+4y= -4. Now, all you have to do is choose the answer that states exactly that, which is the first choice.
5/6 divided by 3/7?
simple mi amigo!~
7* 5= 35
3*6= 18
= 35/18
= 1 17/18
Answer:
D)
