A. both the equations are identities , i’m pretty sure
Oh wait i got it give me a sec <span>To </span>calculate percentage<span> decrease: First: work out the difference (decrease) between the two numbers you are comparing. Then: divide the decrease by the original number and multiply the answer by 100. If your answer is a negative number then this is a </span>percentage<span> increase.</span>
The answer is 8 and yea it’s 2 steps first u have to remove the constant so u subtract 74-2=72 and 2-2=0. After u get rid of the constant u divide both sides by 9 basically 72/9 and 9/9 which is 8. So n is equal to 8 I hope this helped. I know it can be confusing
12
x 10
______
120
it's pretty simply,sorry if I got it wrong,i'm kinda tired<span />
Well we know that total percentages always equals 100 so x + 45 = 100. You should get x = 55%
