Answer:
10 boys, 15 girls
Step-by-step explanation:
Original ratio: 2 boys/3 girls
let x be the scale factor of the ratio
2x plus 5 boys over 3x girls = 1 (because the # of boys/girls are the same)-------> 2x+5/3x = 1
Simplify: 2x+5=3x
Simplify: 5=x
plug x back into the original ratio: 10/15
Check: 10/15 = 2/3
10 boys + 5 boys = 15, 15/15 = 1
Is that x squared? Cause if so then the answer would be f= 5
I guess choice D is the best answer.
It is a dependent variable <span>is NOT true about an explanatory variable.</span>
It can be done so in simple daily calculations such as calculating how much money you'll have after after you spend some.
<span>$100- $52= $48
and
if you switch it into an addition problem you will get
$100+(-52)= $48,
Or you can get $48 + $52 = $100</span>
Answer:
$260
Step-by-step explanation:
GIven
P=$250
R=4%
T=1 year
The total amount of simple interest is
A=P(1+rt)
substitute
A=250(1+0.04*1)
A=250(1.04)
A=250*1.04
A=$260
Hence the total amount is $260
