Answer:

A) 5

Step-by-step explanation:

6(2x+a)=12x+30

6*2x+6*a=12x+30

12x+6x=12x+30

6a=12x+30-12x

6a=30

a=30/6

a=5

Answer: A is the answer

Step-by-step explanation:

If you plug in a variable for x (I did 2) and then plug in 5 (which is A) here is what you get-

6(2*2+5)=12*2+30

6*9=24+30

54=54

chubhunter [2.5K]
The answer is not reasonable because even though the actual attendance for the super bowl was well over 100,000, it did not even make it to 150,000 which would make the 1 in the hundred thousands place round up to 2.

Tickets for the homecoming dance cost $20 for a single ticket or $35 for a couple. Ticket sales totaled $3280, and 128 people at
ZanzabumX [31]

Answer:

16  singles, 56  couples

Step-by-step explanation:

There's two linear equations that we can make: one for money and one for people. Let the number of single tickets be  s  and the number of couple tickets be  c .

We know that the amount of money we make is  $  =  20 s + 35 c = 2280

We also how many people can come  P  = 1 s + 2 c = 128

We know that both  s  are the same and both  c  are the same. We have two unknowns and two equations, so we can do some algebra to solve for each.

Take the first minus twenty times the second: 20 s + 35 c  =2280

− 20 s − 40 c = − 2560

− 5 c = − 280 ⇒ c = 56

Plugging this back into the second equation, s + 2 c = s + 2 ⋅ 56 = s + 112 = 128 ⇒ s = 16

Mr. Conner is placing stone tiles to make a patio. Each tile is 1 square foot. The drawing shows the dimensions of his patio.
White raven [17]

This question is incomplete

Complete Question

Mr. Conner is placing stone tiles to make a patio. Each tile is 1 square foot. The drawing shows the dimensions of his patio. A quadrilateral is broken into a triangle and rectangle. The triangle has a base of 20 feet and a height of 6 feet. The rectangle has a base of 20 feet and a height of 12 feet. How many total stone tiles will Mr. Connor need for the patio?

Answer:

300 tiles

Step-by-step explanation:

From the above question, we know that the patio is a combination of a triangle and a rectangle.

Step 1

Find the area of the shape

a) Area of the Triangle = 1/2 × Base × Height

Base = 20 feet

Height = 6 feet

Area = 1/2 × 20 × 6

Area = 60 square feet

b) Area of the rectangle

= Length × Breadth.

The rectangle has a

Base = Breadth = 20 feet

Height = Length = 12 feet

Area = 20 × 12 = 240 square feet.

Total Area of the patio

= Area of Triangle + Area of square

= 60 square feet + 240 square feet

= 300 square feet

Step 2

We are told that each stone tile = 1 square foot.

Hence, if the total area of the patio = 300 square feet, the number of stone tiles that would be used is

1 square foot = 1 stone tile

300 square feet = 300 stone tiles.

Therefore,the total stone tiles that Mr. Connor will need for the patio is 300 stone tiles.
