C+A=380
C*1.5+A*4=1070

Multiply first equation by 4 and subtract the second equation from the first:

C*2.5=450
C=180
A=200

Weird.....more adults than children at the amusement park?

Three types of shirts sold at a store cost $8.00, $11.00 and $13.50. One day the store sells a total of 35 shirts

The equations are listed below

What is an equation?

An equation is a formula in mathematics that expresses the equivalence of two expressions by linking them with the equals symbol =. The word equation and its cognates in various languages may have somewhat different definitions; for example, in French, an équation is defined as including one or more variables, but in English, an equation is any well-formed formula consisting of two expressions linked by an equals sign.

The system of equations are:

9x + 11y + 12.50z = 243

x + y + z = 23

z = 2y

x = 11 shirts

y = 4 shirts

z = 8 shirts

Sarah is going to a higher a DJ for her party. DJ iceman charges an initial fee of $100 in addition to $21 per hour. DJ chomp ch

nalin [4]

First you make an equation and establish a variable.
x=amount of hours the DJs will charge the same amount
100+21x=150+15x
Now you solve for x and that will get you your answer.
100+21x=150+15x
-21x -21x
100=150-6x
-150 -150
-50=-6x
8.3333...=x
You can round the answer to $8.33
Hope I helped.

On a coordinate plane, solid circles appear at the following points: (negative 3, 2), (negative 3, 3), (1, 4), (1, negative 4),

goldenfox [79]

Answer: Three points

Step-by-step explanation:

(-3,2) (-3,3) (1,4) (1,-4) (2,-4) (2,-2)

Looking at these points we could say there all doesn't represent a function because each input doesn't exactly assigns one output.

for example -3 the input assigns two different outputs 2 and 3

1 the input also assigns two different outputs 4 and -4

and lastly 2 the input assigns two different outputs -4 and -2

This makes it not a function but if we take away the coordinates

(-3,3) ( 1,-4) and (2,-4) it becomes a function because you will have the coordinates (-3,2) (1,4) (2,-2) and as you could see every input has exactly one output.

Monique is factoring the expression 4 x + 16 x y. Her work is shown below.

svp [43]

Answer:

Monique made an error when writing the factored expression

Step-by-step explanation:

Monique's work:

Factors of 4x: 1, 2, 4, x

Factors of 16xy: 1, 2, 4, 8, 16, x, y

GCF: 4x

Factored expression: 4 x (0 + 4 y)

Correct working:

Factors of 4x: 1, 2, 4, x

Factors of 16xy: 1, 2, 4, 8, 16, x, y

GCF: 4x

Factored expression: 4 x (1 + 4 y)

Therefore, Monique made an error when writing the factored expression

Check:

4x(1 + 4y)

Opening bracket

4x + 16xy
