The first thing we are going to do for this case is define variables.
 We have then:
 x = Number of boys
 y = Number of girls
 We now write the system of equations:
 x / y = 11/9
 x = y + 124
 Solving the system we have:
 x = 682
 y = 558
 The number of students is:
 x + y = 682 + 558 = 1240
 Answer:
 
the total students in the school is:
 
1240 students

PLEASE HELP ME WITH MATH
Alexxandr [17]

Answer:

down below

Step-by-step explanation:

1) 4% of 120 = 4.8, so 120+4.8 = 124.8 cm tall

2) 12% of 6000 = 720 .  6000-720 = 5280 gallons

3) 22% of 200 = 44 . 200-44 = 156

4) 30% of 40 - 12 .   40 - 12 = $28

5) 35% of 140 = $49 .  140 + 49 = $189

Find the value of $1000 deposited for 10 years in an account paying 6% annual interest compound
Romashka [77]

Answer:

You have to use the formula for compound interest which is: A=P(1+r/n)^nt

The Givens info is:

A=?

P=1000

r= 6% = 0.06 (convert into decimal)

n=12(# of interest periods: since it is monthly n=12)

t=10

Now your formula should look like this:

A= 1000*(1+(0.06/12))^12*10

A=1000*(1.005)^120

A=1000*(1.819396734)

A=$1819.40

If x-1/3 = k and k = 3, what is the value of x ?<br> A) 2<br> B) 4<br> C) 9<br> D) 10
Semenov [28]

Answer:

None of the above

Step-by-step explanation:

x-1/3 = k

We know that k=3, so we can substitute that into the equation

x-1/3 = 3

Add 1/3 to each side

x-1/3 + 1/3 = 3+1/3

x = 3 1/3 or as an improper fraction 10/3
