Answer 1
Answer:

Answer:

x = 11, x = -11

Step-by-step explanation:

I know this is kind of late but the two previous answers were wrong.

We have x² = 121. To find x, we need to get rid of the exponent, and to do this, we can take the square root of both sides:

√x² = √121

x = √121

You might think that x = 11 but remember, x can be negative as well because you can square negative numbers. Basically, every real number has two square roots - a positive and a negative one. So, the answer isn't just x = 11, it's also x = -11 because (-11)² = 121 as well.

16. 8h = p 17. 288 = 18h, 16 = h. She is making $16/h, so if she works 11 hours making that same amount, 11(16) = p, she would make $176. 18. I’m not sure. 19. 24/60 = 0.4 x 100 = 40%. 20. I’m assuming you already solved it? 21. 30 x 0.63 = 18.9 22. 81 x 0.6 = 48.6 31. 40 x 0.55 = 22. Since the item is on sale for 55% this means the price decreased by $22, so 40 - 22 = 18, so Nicole payed $18. 32. 881.95 x 1.65 = $1455.22 33. 48300 x 1.38 = 66654 34. 442 x 1.35 = $596.7 35. 221/130 = 1.7 x 100 = 170 % This is all I’ll do for now, I’ll probably come back to do more if someone hasn’t by then, but I hope this helped.

Can you guys help me with fractions I forgot over the summer. Please explain easily.

Answers

So in order to add the fractions together you need to first find a common denominator. For the very first problem you can use 63 as a denominator because 7*9=63. Now for the numerator. So you have 4/7 and 8/9. We just multiplied 7 by 9 so now we need to do that for 4 also. 4*9=36. Now we have 36/63. For 8/9 we multiply 8 by 7 to get 56. Now we have 36/63 + 56/63. Once you add those together you simplify your answer.
