Answer:
D
Step-by-step explanation:
To compare the two, get the same denominator, so multiply -8/18 by 27 on the numerator and denominator, and multiply -17/27 by 18 on the numerator and denominator. That gives -216 /486 and -306 /486. On a number line, the one on the left is less. That greater than symbol is correct. Both to the left of 0, -8/18 on the right of -17/27.
Answer:
Step-by-step explanation:
There are four 8s, so s should represent one 8.
The 12 is made up of 4 * 3, so B should be the answer.
Answer: B or 4(s + 3)
When the brackets are removed, you get 4s + 12
Answer:
r = 1/2(s -t/x)
Step-by-step explanation:
Here, we simply want to make r the subject of the formula;
We proceed as follows;
s = 2r + t/x
s - t/x = 2r
Divide both sides by 2
r = 1/2(s - t/x)
The expression 5x+3 would be three more than five times a number! More than in this case would be addition - so if you get the same problem with subtraction you just change more to less!
Basically what it's tell you is that if x stood for 2 in this case 5*2 = 10 since it's 3 MORE than 5 times a number (x is in place of a number), you're adding 3 to 10 and that gives you 13!
I hope I simplified it a little more and you understand!
Good luck, rockstar! c: I hope this helped!
