Step-by-step explanation:
Ax − B = C
Dy + E = F
Solve for x and y:
x = (B + C) / A
y = (F − E) / D
So the sum of x and y is:
x + y = (B + C) / A + (F − E) / D
For x + y to be as large as possible, A, E and D must be small, and B, C, and F must be large. With some trial and error:
x + y = (9 + 8) / 1 + (7 − 3) / 2
x + y = 17 + 2
x + y = 19
For x + y to be as small as possible, we want the first term to be a small fraction, and the second term to be as negative as possible. So A must be large, B + C must be small, F must be less than E, and D must be small.
x + y = (3 + 4) / 8 + (2 − 9) / 1
x + y = ⅞ − 7
x + y = -6⅛

Item 4 The sum of the angle measures of the polygon is 540°. Write and solve an equation to find the value of x. An equation is =540. The solution is x= .
Answers
Let's set the sum of the angle measures equal to 540 degrees.
139 + 3x + 5x - 10 + 10x - 9 + 3x = 540
Let's combine like terms.
21x + 120 = 540
Subtract 120 from both sides.
21x = 420
Divide both sides by 21
x = 20

The answer is B.
In order for this chart to be true, each x and y pair must be proportional to the other ones. (in other words, each row of x and y should increase the same amount as the other ones.)
look at the first row. we can write this as 3/5 (x over y). then look at the third and fourth row. 6/10 = 3/5, and 9/15 = 3/5, so the pairs are proportional.

Julie and her family go to the movies. They buy 2 adult tickets and 3 child tickets. An adult ticket costs $3.50 more than a child ticket. Julie's family spends $35.75. What is the cost of the adult ticket?
HELP PLS
Answers
Answer:
$9.25
Step-by-step explanation:
let x = the cost of a child ticket
3(x)+2(x+3.50)=35.75
3x+2x+7=35.75
5x=28.75
x=5.75 cost of child ticket
5.75+3.50= 9.25
Answer:
$9.25
Step-by-step explanation:
Start by multiplying 2 by 3.5. This will give you 7. Then subtract 7 from 35.75, which gives you 28.75. This is the full amount for five child tickets. Then you want to divide 28.75 by 5, giving you 5.75. This is the amount for a single child ticket, and because we know that an adult ticket is 3.50 more than a child ticket, you add 3.50 and 5.75, which gives you your final answer of 9.25.

1. You need to find the arena of the missing piece so with the 40 on top you will subtract 12 which will give you 28
2. To find the other side subtract 28-12 to get 16 then you will multiple then together to get 448
3. Now just Multiply 40 and 28 to get 1120
4. Subtract 1120 and 448 and you’ll get the answer of 672

The current price for gasoline is $3.049 per gallon. A customer puts 7.45 gallons in her car. How much does she pay for the gas? Round your answer to the nearest cent.
Answers
Answer:
$22.72 for gas
Step-by-step explanation:
If each gallon costs $3.049, then we multiply the cost of each gallon by 7.45
3.049 x 7.45 = 22.71505
As the question asks us to round to the nearest cent in 22.71505, we would round up.
Your answer is $22.75 for gas
