-26n -22= n - 90
-26 times a number: -26n
minus 22: -22
equal: =
90 less than a number: n - 90
Solving the Equation:
Move n to the left side of the equal sign (which becomes -n) in order to combine like terms:
-26n-n-22= -90
Move -22 to the right side of the equal sign which becomes +22
-26n-n=-90+22
solve both sides; -26n-n= -27n and -90+ 22= -78
-27n=-78
n= 2.888888
Answer:
w = 16.875 inches
Step-by-step explanation:
Given that the ratio of the length to width in a full-size cello is approximately 8 to 3.
This will be a constant for all cellos
Using the above we can find out length if we know width and vice versa.
Here we know the length = 45 inches
Since 
BY cross multiplication we find that
8w = 3(45)
Or w = 16.875 inches
Verify:
Let us check our answer by comparing with proportion
l/w = 45/16.875 = 8/3
Hence our answer is right

Answer:
x = ±3√2i
Step-by-step explanation:
Add -18 to both sides of the equation:
x^2 = -18
Take the square root of both sides:
x = ±√(-18)
Remember that 18=9·2 = (3^2)·2 and √-1 = i. Simplify.
x = ±(√(3^2))·(√2)·(√-1)
x = ±3√2i
