Answer:
2x - 6 = 5x-10 ... 4. 2x-1= x - 5+ 3x. 2x-1=4x-5. - +5 +5. 5. 3(y-1)=-(4-5). 3y-3 = -4+5. +y
Step-by-step explanation:
Answer:
23y-8
Step-by-step explanation:
First add together all of the terms that are next to a variable:
2y+10y+5y+6y=23y
Then add together all of the integers that are alone:
-9+10+(-7)+(-2)= -8
Add the two terms together and you get:
23y-8
Option( d ) is the correct one.
Multiplying both sides of this equation by 3, to eliminate the fraction, we get:
9 + m = 6.
Next, we subtract 9 from both sides to isolate m: m = 6 - 9 = -3
Then m = -3.
Check: Subst. -3 for m in this equation:
9 - 3 6
------- = ------ = 2 (as expected). Thus, m = -3 is correct.
3 3
Problem #10:
4n - 9 = -9 Add 9 to both sides: 4n = -9 + 9 = 0.
Divide both sides by 4: n = 0.
Check: Substitute 0 for n: 4(0) - 9 = -9 is true.
The answer would be 30 since for 180 pounds and 60 feet you would need to divide 180 by 60 to get the unit rate for the pressure and then multiply by 10 which would get you 30. Correct me if I’m wrong. Hope it helps :)
