A school luncheon made $630. Adult tickets cost $11 each and child tickets cost eight dollars each. The number of children was half the number of adults. How many of each ticket were sold?

Answers

Hello! Lets first start with defining our variables:
a = adult tickets
c = child tickets
Now let’s set up a system of equations:
11a + 8c = 630
c = 1/2a (this can be confusing to some people but the CHILDREN TICKETS = HALF THE ADULT TICKETS)
Ok now we have to solve this:
11a + 8c = 630
c= 1/2a [you can solve this system of equations using substitution!]
11a + 8(1/2a) = 630
11a + 4a = 630
15a = 630
a = 42 (now we know our a value and we can plug that in to find c!)
c = 1/2a
c = 1/2(42)
c = 21
you can check this by plugging in your c and a value into both equations! I hope this helps! :)
Answer: a=42, c=21

Answer:

RST

Step-by-step explanation:

The question is asking you to complete the congruence statement. In a congruence statement, the corresponding angles must be in the same order they are in, in the first half of the statement. In the first triangle <M=79, <N=60, and <O=42. So the other half must be in this same order. In the other triangle <R=79, <S=60, and <T=52, which is why the answer is RST.

Complete the statement :

[tex]\color{plum}\tt2x + 7° = \underline{65} \: degrees[/tex]

Steps to derive the correct solution :

The exterior angle corollary states that the measure of a triangle's exterior angle is the sum of the opposite interior angles of the exterior angle.

Which means :

∠36° + ∠x° = ∠(2x + 7)°

Let us solve this equation to find the measure of the exterior angle :

[tex] =\tt 2x + 7 = 36 + x[/tex]

[tex] = \tt2x + 7 - x = 36[/tex]

[tex] =\tt x + 7 = 36[/tex]

[tex] = \tt \: x = 36 - 7[/tex]

[tex] =\tt x = 29[/tex]

Thus, the measure of ∠x = 29°

Then, the measure of the exterior angle :

[tex] = \tt2 \times 29 + 7[/tex]

[tex] = \tt58 + 7[/tex]

[tex] = \tt65[/tex]

Thus, the measure of the exterior angle 2x+7 = 65°

Let us check whether or not we have found out the correct measure of each angle by placing 29 in the place of x:

[tex] = \tt2 \times 29 + 7 = 36 + 29[/tex]

[tex] =\tt 58 + 7 = 36 + 29[/tex]

[tex] = \tt65 = 65[/tex]

Since the measures match we can conclude that we have found out the correct value of each angle.

Therefore, ∠2x + 7° = 65°

Suppose that IJK is isosceles with base IJ.
Suppose also that m<1 = (3x +18) and m Find the degree measure of each angle in the triangle.

Answers

Answer:

m<I=57

m<J=57

m<K=66

Step-by-step explanation:

All the angles in a triangle add up to 180 degrees.

m<I= 3x+18

m<K= 5x+1

m<I is congruent to m<J.

We can plug the information we already know into the equation.

3x+18+3x+18+5x+1=180

11x+37=180

Subtract 37 from both sides.

11x=143

x=13

Now, we can find out what the angles are.

m<I= 3x+18

m<I=3(13)+18

m<I=39+18

m<I=57

We know that m<I=m<J, so they are both equal to 57 degrees.

m<J=57

Now for m<K:

m<K=5x+1

m<K=5(13)+1

m<K=65+1

m<K=66

We know this is correct because 57+57+66=180.

John began his job making $125 the first week. After that he ws paid $6.25 per hour. Write the equation in slope intercept form to represent the situation.

Answers

Answer:

y=6.25x+125

Step-by-step explanation:

Given that,

John began his job making $125 the first week. After that he was paid $6.25 per hour.

Here $125 is fixed and $6.25 increase per hour. It means we can write the equation as follows :

y = 125 + 6.25 x

The general equation for the slope-intercept form is given by :

y = mx+x

m is slope

So, the equation in slope intercept form is given by :

y=6.25x+125

Hence, this is the required solution.

a)  y= 0.05x + 16

b)  y= 6.25x + 125

c)  y= 2x + 10

d)  y= 3x + 5

Answer: B) y = 6.25x + 125

Answer:

Step-by-step explanation:

Ally gives her sister = 1/5 stickers

Ally gives her cousin = 1/5 of the remainder stickers

Assume Number of sticker Ali has = 1

Remainder after giving stickers to her sister = 1 - 1/5 = 4/5

Number of stickers she gave her sister = [tex]\frac{1}{5}\times\frac{4}{5}[/tex]

         =[tex]\frac{4}{25}[/tex]

Sticker she has = [tex]1-\frac{1}{5}-\frac{4}{25}[/tex]

=[tex]\frac{25-5-4}{25}[/tex]

=[tex]\frac{16}{25}[/tex]

Sticker left with Ally is equal to [tex]\frac{16}{25}[/tex].
