Okay, 72 degrees is equal to (5x-98), so
72=5x-98
5x=170
x=34
So now that we know that x=34, we can put 34 into (5x-98), so 170-98
170-98 and y are supplementary, so they add up to 180 degrees. So the equation is
170-98+y=180
72+y=180
y=180-72
y=108
Distribute the -4. Then combine like terms.
24 - 4(5y - 6z) + 3y - 7z =
= 24 - 20y + 24z + 3y - 7z
= - 20y + 3y + 24z - 7z + 24
= -17y + 17z + 24
8. 3x-4>38
3x>38+4
3x>42
x>42/3
x>14
So the answer is A. x>14
9. It's A. Two less than four times a number is 12. Because 4x (four times) and also it says 2 less than 4 times a number...
Hello!
We know that
(x - 10) * 3 = 2x
Distribute the 3
3x - 30 = 2x
Subtract 2x from both sides
x - 30 = 0
Add 30 to both sides
x = 30
The answer is 30
Hope this helps!
