Answer: 150 boys
Step-by-step explanation:
Let the number of boys be x
Since there were 200 more girls than boys, the number of girls will be: = x + 200
Since the ratio of boys to girls was 3:7, this can be solved further below:
3/7 = x/x+200
Cross multiply
(7 × x) = 3(x + 200)
7x = 3x + 600
7x - 3x = 600
4x = 600
x = 600/4
x = 150
The number of boys enrolled is 150
Number of Girls will be:
= X + 200
= 150 + 200
= 350
Check: Number of boys / Number of girls
= 150/350
= 3/7
= 3:7
Answer:
x = π(n - 
)
Step-by-step explanation:
Find attached Solution
So use undistributive properyt]
ab+ac=a(b+c)
so factor 24a dadn 28 to find 'a' the common factor
24=2 times 2 times 2 times 3 tiems a
28=2 times 2 times 7
common one is 2 itmes 2=4
a=4
4(2 times3 times a)+4(7)=4(6a)+4(7)=4(6a+7)

Answer:
(12480 -3600)/48
Step-by-step explanation:
Assuming a 0% interest rate, the monthly payment will be 1/48 of the amount remaining after the down payment:
(12480 -3600)/48

= 185
Answer:
[3x + (y/2)]
Step-by-step explanation:
English Translation
Suppose we have x confirmed cases of coronavirus and y suspected cases. A - If the confirmed cases triple and half of the suspects fall, we will have the following expression to represent the total number of cases:
Solution
Number of confirmed cases = x
Number of suspected cases = y
Number of confirmed cases triples and becomes 3x
Half of the suspected cases fall and becomes (y/2)
Total number of cases then becomes
[3x + (y/2)]
In Portugese/Em português
Número de casos confirmados = x
Número de casos suspeitos = y
O número de casos confirmados triplica e se torna 3x
Metade dos casos suspeitos cai e se torna (y / 2)
O número total de casos passa a ser
[3x + (y / 2)]
