Answer:

I think it is 4 but, im not sure

Answer: You can put this solution on YOUR website!

let's call the number of adults a and the number of children c.

so the total adults plus the total children equals 40 or a+c=40 or c=40-a

also we know that 8a+5c=272

substituting c's value in the 1st equation into the 2nd equation we get

8a+5(40-a)=272---->lets distribute that left side---->8a+200-5a=272

now let's combine like terms on either side of the equals sign.

3a=72 a=24

so we have highlight%2824-adults%29

and c=40-a(24)=highlight%2816-children%29

The expression for the total amount she charged can be represented as A = 20n.

A mixture of variables, numbers, addition, subtraction, multiplication, and division are called expressions.

For example 2x = 54

An expression is a mathematical proof of the equality of two mathematical expressions.

Given that,

She will charge $20 for every lawn

Number of lawns she mows = n

Total charge let's represent by A

Then,

A = 20n will be the correct expression.

Hence "The expression for the total amount she charged can be represented as A = 20n".

Answer:

Lara hiked for 2 hours.

Step-by-step explanation:

1 cup = 8 ounces

4 cups = 32 ounces

32 - 10h = 12

10h = 20

h = 2

Lara hiked for 2 hours.

A cup contains 8 fluid ounces so the total number of ounces that Lara had before the hike was:

= Number of cups x fluid ounces per cup

= 4 x 8

= 32 fluid ounces

After the hike, Lara was left with 12 fluid ounces which means that she consumed:

= 32 - 12

= 20 fluid ounces

She drank 10 fluid ounces per hour so the total number of hours she hiked were:

= Number of fluid ounces consumed / Fluid ounces per hour

= 20 / 10

= 2 hours

$1017.19

Step-by-step explanation:

First find the fraction of how much of Paulo's money is spent on his rent and car. Add 1/4 and 1/8, which is 3/8 because 1/4 = 2/8. Then multiply 3/8 by Paulo's monthly spending, which is $2712.50. Multiplying those numbers will get you $1017.1875. which you have to round up to $1017.19 because you can't spend three quarters of a cent.

Answer:

Asumming that you are rounding to the nearest hundreth:

1,017.19

Step-by-step explanation:

Find [tex]\frac{1}{8}[/tex] of 2,712.5 to find how much money Paulo spends on his car.

[tex]\frac{1}{8}[/tex] = .125

Multiply 2,712.5 by .125

2,712.5 × .125 = 339.0625 ≈ 339.06

Now, find [tex]\frac{1}{4}[/tex] of 2,712.5 to find how much paulo spends on his rent.

[tex]\frac{1}{4}[/tex] = .25

Multiply 2,712.5 by .25

2,712.5 × .25 = 678.125 ≈ 678.13

Add the two values together to get your answer

339.09 +

678.13

----------

1,017.19

(Another way to dolve this problem would be to find [tex]\frac{5}{8}[/tex] of 2,712.5 and subtract it from the origional value, 2,712.5)

Given the functions from the question f(x)  = 3x + 4

If h(x) = f(x+3)

Replace x with x+3 in the function f(x) to have;
