If 4m =130 does 4m÷4=130

2 answers:

No because you would be dividing the first equation by four, for an example if m=32.5 in the first equation, if you put that into the second equation and divide it by four you won’t get 130 like in the first equation

Answer:

Step-by-step explanation:

if 4m=130 then that means m=32.5

if 4m/4=130 then that means m=130 which is not the same as 4m=130

Lelu [443]

Answer:

finance charge refund is $91.53

Step-by-step explanation:

given data

finance charge F = $476

time t = 12 month

no of payment n = 5

to find out

finance charge refund

solution

we will apply here finance charge refund formula that is

finance charge refund = F × $\frac{n * (n+1)}{t* (t+1)}$

put here value we get

finance charge refund = 476 × $\frac{5 * (5+1)}{12* (12+1)}$

finance charge refund = 476 × $\frac{5 * (6)}{12 * (13)}$

finance charge refund = 476 × $\frac{30}{156}$

finance charge refund = 476 × 0.1923

finance charge refund = 91.53

so finance charge refund is $91.53

Cna i get some help with dis plz

Let $b_1,b_2,\ldots,b_{20}$ be the 20 marks of the boys, and $g_1,g_2,\ldots,g_{10}$ be the 10 marks of the girls.

We know that the global mean was 70, meaning that

$\dfrac{b_1+b_2+\ldots+b_{20}+g_1+g_2+\ldots+g_{10}}{30}=70$

Multiplying both sides by 30 we deduce that the sum of the scores of the whole classroom is

$b_1+b_2+\ldots+b_{20}+g_1+g_2+\ldots+g_{10}=2100$

By the same logic, we work with the marks of the boys alone: we know the average:

$\dfrac{b_1+b_2+\ldots+b_{20}}{20}=62$

And we deduce the sum of the marks for the boys:

$b_1+b_2+\ldots+b_{20}=1240$

Which implies that the sum of the marks of the girls is $2100-1240=860$

And finally, the mean for the girls alone is

$\dfrac{860}{10}=86$
