7x - 3(-2) = 23
7x - - 6 = 23 (two minuses make a plus)
so it’s gonna be 7x + 6 = 23
Now you have isolate you x, so move everything else to the other side, but remember to change your sign when transferring to the other side
7x = 23 - 6
7x = 17
To isolate x in this multiple, you divide by 7 (because the inverse of multiplication is division)
x = 17/7
1 byte9 Cube root of b^27 = b^27/3 = b^9.
The median is 48 because it is the biggest number and the biggest number is the median
Answer:
x^-2 = 1/4
x^-1 = -1/2
x^0 = 1
x^1 = -2
x^2 = 4
Step-by-step explanation:
got it right
The least common multiple is : 18
It is the lowest amount that can be reached.
