An equation has an infinite number of solutions if the left and right sides are identical. Let's simplify them both and then decide the value of ?.

Left hand side:

5(x-4)+? = 5x - 20 + ?

Right hand side:

1+12x-21 = 12x-20

So, both sides have a numeric part of -20. We can use the "?" value to make sure that the literal part is the same as well. So, we want

5x+? = 12x \iff ? = 12x-5x = 7x

The length of a rectangle is 2 ft longer than its width.
notsponge [240]
If the length is 2ft longer than it’s width
Let’s assume width as X and so the length will be X+2
Perimeter=40ft
Putting the values into a equation, we get,
X+2+X=40
=2X+2=40
=2X=38
=X=19
Therefore
Length =X+2=19+2
=21ft
Width=X=19ft
Area of rectangle =lxb
= 21x19
3992ft

A sports team came to town. the stadium filled all 10,000 seats at two-level pricing. level 1 tickets are $50 each, and level 2
marissa [1.9K]

x represents the number of tickets of level 1 and y represents the number of tickets of level 2 in the system given that there are 10,000 seats, level 1 tickets are $50 each, and level 2 tickets are $150 each and equation representing the situation:x + y = 10,000, 50x + 150y = 75,000. This can be obtained by understanding the question and observing the equations.

<h3>What do the x and y represent in the system?</h3>

Given that total number of seats is 10,000 and there are two levels pricing.

Thus by observing the equation, x + y = 10,000,

10,000 is the sum of 2 variable which obviously will be the number of tickets in level 1 and number of tickets in level 2.

Since there are two level pricing,

50x + 150y = 75,000 represent the addition of total cost of tickets of level 1 and 2.

Hence x represents the number of tickets of level 1 and y represents the number of tickets of level 2 in the system given that there are 10,000 seats, level 1 tickets are $50 each, and level 2 tickets are $150 each and equation representing the situation:x + y = 10,000, 50x + 150y = 75,000.

SA = 456 cm²

Step-by-step explanation:

small rectangle SA: 6*4 + 6*8 + 6*4 + 6*8 + 4*8 = 176

large rectangle SA: 2*14 + 2*8 + 2*14 + 2*8 + 8*14 + (8*14 - 8*4) = 280

Total SA = 176 + 280 = 456
