To convert fractions into decimals simply divide the numerator (5) by the denominator (8). If you type in "5/8" into a calculator you will receive a compute of 0.625 which you can round to .6
Answer:
B. No solutions
Step-by-step explanation:
8x+2y=14
8x+2y=4
These linear equations are in standard form, and the Ax values are the same (8x) and the By values are the same (2y). The only value that is the different is the C values (14 and 4), which will be the cause of a no solution for this system of equations.
Answer:
x = 9
Step-by-step explanation:
You have to use the Secant Segment theorem:
AB * AC = AD * AE
This means that the external piece of the secant times the whole secant for one is equal to the external piece of the secant times the whole secant for the other.
Now, setup an equation:
8(x + 8) = 4(30 + 4)
Simplify:
8x + 64 = 120 + 16
8x = 72
x = 9
Total sales = $3600
Commission earned on $3600 = $576
Commission rate can be calculated as = 
= 16%
Hence, commission rate is 16%
