Answers:
From as I can see. You need to do a long division on 76 and 9 and then if you got the answer subtract the answer with the girls surveyed and you'll get the answer and multiply the answer with the boys surveyed and then add all the answers together. Hoped this help!!! :)
To solve this problem, we must set up a system of equations. In this case, let's let Maggie's age be represented by the variable m and her brother's age be represented by the variable b. We are told that the sum of their ages is 24, which gives us our first equation: m + b = 24. We can construct our next equation from the first sentence of given information: b = 2m - 3. This makes our system of equations:
m + b = 24
b = 2m - 3
To solve, we are going to substitute the value for b in terms of m given by the second equation into the first equation for the variable b.
m + b = 24
m + 2m - 3 = 24
To simplify, we must first combine the variable terms on the left side of the equation using addition.
3m - 3 = 24
Next, we should add 3 to both sides of the equation to get the variable term alone on the left side of the equation.
3m = 27
Finally, we should divide both sides by 3 in order to get the variable m alone.
m = 9
Therefore, Maggie is 9 years old (using the first equation and substituting in this value you can find that her brother is 15 years old).
Hope this helps!
Answer: The equation doesn't look right, it's either there's too many symbols or you need to switch some things around.

Answer:
115% of 75 is equivalent to 75 by 1.15 = 8.625 , This two are equivalent
Step-by-step explanation:
Given as :
Tyson multiplies 75 by 1.15
I .e 75 × 1.15 = 86.25
Now A ) 115% of 75 = 
× 75 = 86.25
B) 15% of 75 = 
× 75 = 11.25
C) 11.5% of 75 = 
× 75 = 8.625
D) 1.15% of 75 = 
× 75 = 0.8625
∵ 115% of 75 is equivalent to 75 by 1.15 , so Tyson try to find the option A
Answer
Answer: interest at the end of 3 years is $495.72
Step-by-step explanation:
The formula for simple interest is expressed as
I = PRT/100
Where
P represents the principal
R represents interest rate
T represents time in years
I = interest after t years
From the information given
T = 3 years
P = $3,672
R = 4.5%
Therefore
I = (3672 × 4.5 × 3)/100
I = 49572/100
I = 495.72
