Supplementary angles sum to 180 degree

Let one angle be x

Then the other angle is x+80

Summing the 2 angle gives

x+x+80=180

2x+80=180

2x=180-80

X=50

Thus the angles are 50 degree and 50+80= 130 degree

ariana grande is coming to north gulfport middle school for a fundraising benefit concert!Nevaeh is selling tickets.This week,sh

ArbitrLikvidat [17]

Answer:

Adult = $7

Kids = $4

Step-by-step explanation:

Before we can find the price of the tickets, we first need to create expressions that can be used to explain the prices.

Let x = Price of kids tickets

Let y = Price of adults tickets

For this week the expression is:

3x + 9y = 75

For the last week the expression is:

8x + 5y = 67

Now to be able to find the value of x or y, we can use the Solving Linear Equations by Multiplying First Method.

3x + 9y = 75

8x + 5y = 67

Now we need to remove either the x or y by multiplying the whole expressions by a certain number.

8(3x + 9y = 75)

24x + 72y = 600

3(8x + 5y = 67)

24x + 15y = 201

Now that we have our equations and we can eliminate the x by subtracting both expressions.

24x + 72y = 600

57y = 399

To find the value of y, we divide both sides by 57.

$\dfrac{57y}{57}=\dfrac{399}{57}$

y = 7

Now that we have the value for y, we simply substitute the value in any of our expressions.

3x + 9y = 75

3x + 9(7) = 75

3x + 63 = 75

3x = 75 - 63

3x = 12

Now we divide both sides by 3 to find the value of x.

$\dfrac{3x}{3}=\dfrac{12}{3}$

x = 4

So the ticket prices are:

Adult = $7

Kids = $4

Evelyn can run 3 miles in 40 minutes. Which equation can be solved to find m, the number of miles Evelyn can run in 60 minutes?

inna [77]

Answer:

m= 4.5 miles

Step-by-step explanation:

Let the number of miles Evelyn can run be m and can be modeled by the equation below

m= kx

Where x Is the Minutes

When m= 3

x= 40

3= k40

k= 3/40

If x= 60

m=3/40(60)

m = (60*3)/40

m= 180/40

m= 4.5 miles

kupik [55]

For this type of question, you just need to multiply the percentage with the number
so, the calculation would be

47.2% x 300

47.2/100 x 300

47.2 x 3

= 141.6
