Answer:
Numerator = 18
Denominator =75
Step-by-step explanation:
Given the expression
9/15=x/30=45/x
We can equate any two fractions
9/15= x/30
Criss multiply
15x = 9×30
15x = 270
x = 270/15
x= 18
Numerators is 18
Similarly
9/15 = 45/x
1/15 = 5/x
x = 5×15
x = 75
The denominator is 75
You would multiply 48 by 6, giving you 288 windowpanes
One way to check if 102 ÷ 6 = 17 is by focusing on the left side of the equation.
102 ÷ 6 can be converted into 
can be simplified, lets start by dividing the numerator and denominator by 2.
\frac{102/2}{6/2} = \frac{51}{3}
= 
can be rewritten as 17.
No solution since the two equations do not intersect
Answer:
$11,170
Step-by-step explanation:
First you convert the percentage to decimal form out of 100 (which you divide)
3.9%/100 = 0.039
A = P(1 + rt)
A = 10000(1 + 0.039 * 3) ( * = multiplication)
I = $11,170 - 10,000 = $1,170
Which you should get $1,170.00 or $1,170 (which is pretty much the same thing)
Hope this helps!
