Answer:
Step-by-step explanation:
a. To solve for "y" you want to isolate the variable. What this means is you want to keep "y" on its own. To do this first we will subtract 2x from the equation making 4y = 36 - 2x. Next, we will get rid of 4 to do this divide 4 from both sides. y = (36 - 2x)/4
*I have to go in a bit so sry for no explenation*
b. h = 2a/b
c. x = 1/4y + -3/4
A would be your answer I believe
Answer:
13=x
Step-by-step explanation:
Side-spliting theorem
21/(x-4)=14/6
cross multiply
21*6=14*(x-4)
distribute 14
126=14x-56
add 56 to both sides
126+56=14x-56+56
leaving you with
182=14x
Divide both sides by 14 to get x by itself
182/14=14x/14
13=x
Simply divide 15.7 by 6.28 to get 2.5 :) easy peasy pumpkin pie
