Bond [772]

Answer: 4051 girls, 4862 boys and 1570 adults over 50 years of age group attended the festival.

Step-by-step explanation:

Let x denotes the number of girls.

Then, the number of boys = x+811

The number of adults over 50 years of age = x-2481

Now, by considering the given scenario :-

x+x+811+x-2481=10483\\\\\Rightarrow\ 3x-1670=10483\\\\\Rightarrow\ 3x=10483+1670\\\\\Rightarrow\ 3x=12153\\\\\Rightarrow\ x=\dfrac{12153}{3}=4051

Thus, the number of girls attended the festival = 4051,

Then number of boys = 4051+811=4862

Number of adults = 4051-2481=1570

Lelechka [254]

Using proportions, the amount of money that Sam would need each month to pay his bills is of:

b. at least $425.32.

<h3>What is a proportion?</h3>

A proportion is a fraction of a total amount, and the measures are related using a rule of three.

In this problem, his annual social security benefit is of 42% of $37,991, hence:

A = 0.42 x 37991 = $15,956.22.

Hence the monthly amount is given by:

M = 15956.22/12 = $1,329.68

He needs $1,755 monthly, hence the amount he needs is of at least:

An = 1755 - 1329.68 = $425.32.

Which means that option b is correct.

What’s the x and y intercept of 8x+5y=-48
Anuta_ua [19.1K]

Step-by-step explanation:

8x + 5y =  - 48 \\  \\ at \: x = 0 \\  \\ 8 \times 0 + 5y =  - 48 \\  \\  \therefore \: 5y  = - 48 \\  \\  \therefore \: y  =  \frac{ - 48}{5}  \\  \\ \therefore \: y  - intercept =   - 9.6 \\  \\ at \: y = 0 \\  \\ 8 x + 5 \times 0 =  - 48 \\  \\  \therefore \:8x  = - 48 \\  \\  \therefore \: x  =  \frac{ - 48}{8}  \\  \\ \therefore \: x - intercept =   -6 \\  \\
