ANSWER

8x + 3y = 2000

x => The number of adults

y => The number of children

EXPLANATION

Let the number of adults be x.

Let the number of children be y.

Each adult will be charged $8 admission. This would mean that the charges for x adults will be:

8 * x = $8x

Each child will be charged $3 admission. This would mean that the charges for y children will be:

3 * y = $3y

The club wants to earn $2000 from admission charges. This means that adding the total charges for adults and children should yield $2000.

Therefore, we have:

8x + 3y = 2000

The variables are:

x => The number of adults

y => The number of children

How do I find the measure of the interior angle?
nataly862011 [7]

Answer:

see the explanation

Step-by-step explanation:

we know that

The sum of the interior angles in any polygon is given by the formula

S=(n-2)180^o

where

n is the number of sides of the polygon

step 1

Find the sum of the interior angles in the given polygon

we have

n=5\ sides

substitute

S=(5-2)180^o=540^o

step 2

Find the value of x

we know that

-3x+125+(45-x)+(-x+90)+80=540

solve for x

-5x+340=540

-5x=200\\x=-40

step 3

Find the measure of each interior angle

substitute the value of x

Angle A

-3(-40)=120^o

Angle B

80^o

Angle C

-(-40)+90=130^o

Angle D

45-(-40)=85^o

Angle E

125^o

There are 84 boys in the 6th grade class. If boys make up 30% of the 6th graders, how many students are in this whole 6th grade
koban [17]
<h3>Answer:  280</h3>

Work Shown:

x = number of students in the 6th grade class

30% = 30/100 = 0.30

30% of x = 0.30x this is equal to 84 since "30% of the 6th graders are boys (and there are 84 boys in sixth grade)", so we say 0.30x = 84

Divide both sides by 0.30 to isolate x

0.30x = 84

0.30x/0.30 = 84/0.30

x = 280

So there are 280 students overall in the 6th grade class.

In which step did Viet make an error?
Yuri [45]

Answer:

Step 1

Step-by-step explanation:

When moving the 4 to the other side, Viet was supposed to subtract 4 from each side, leaving 0 on the left, and 102-4 on the other side. 102-4=98, not 106. Viet added when he was supposed to subtract.
