Answer:
7x+1
Step-by-step explanation:
When you look at the expression(3x+2+4x-1), you will notice that some have variables while some are just regular numbers.
First, focus on the variables. 3x and +4x. In the expression, you will have to add it so 3x+4x will be 7x. Now, keep 7x on the side and switch to the numbers.
Next, focus on the numbers. 2 and -1. All you have to do is combine them which will be 2-1 which also equals 1.
Finally, return 7x with 1 which will be 7x+1. The reason you add a + sign instead of a - sign is because you got positive 1, not negative 1.
Your answer is 7x+1.
I think it is option C, i am not sure tho.
The answer would be 20%
If you subtract 450 and 360 you would get 90. So basically you do 90 divided by 450 and move the decimal point twice
We have: PZ = 1/2 XZ ( Z is the middle point of XZ )
=> 22 = 1/2(5x - 11)
=> 1/2(5x - 11) = 22
=> 5x - 11 = 22 : 1/2
=> 5x - 11 = 44
=> 5x = 44 + 11
=> 5x = 55
=> x = 55/5 = 11
ANSWER: x = 11
Ok done. Thank to me :>
Cost per month is 29 + 0.12m
C = 29+0.12m
m=50
C = 29 + 0.12*50
C = 29 + 6
C = 35
