A service station on the interstate charges $2.29 per gallon for gasoline and $1.89 per quart for oil. What would be a reasonable amount to pay for 10 gallons of gasoline and 2
quarts of oil?
O $20
O $23
O $25
O $27
The reasonable amount to pay for 10 gallons of gasoline and 2 quarts of oil will be $27.
What is Multiplication?
To multiply means to add a number to itself a particular number of times. Multiplication can be viewed as a process of repeated addition.
Given that;
A service station on the interstate charges $2.29 per gallon for gasoline and $1.89 per quart for oil.
Now,
Since, A service station on the interstate charges $2.29 per gallon for gasoline and $1.89 per quart for oil.
Hence, We get;
The cost of 10 gallons of gasoline = 10 × $2.29
= $22.9
And, The cost of 2 quarts of oil = 2 × $1.89
= $3.78
So, The total cost = $3.78 + $22.9
= $26.68
≈ $27
Thus, The reasonable amount to pay for 10 gallons of gasoline and 2 quarts of oil will be $27.

Identify the property being shown here, assuming that a + 2 = y.
(a + 2)/3 = y/3
Assuming that a + 2 = y, the property that was applied to arrived at (a + 2)/3 = y/3 is the: division property of equality.
Recall:
What is done to both sides of an equation will determine what property of equality was applied to the equation.
Thus, given the equation:a + 2 = y
The following was obtained:(a + 2)/3 = y/3
Observing the equation stated above, we will see that both sides of the equation was divided by three. This makes both sides equal.
Therefore, assuming that a + 2 = y, the property that was applied to arrived at (a + 2)/3 = y/3 is the: division property of equality.

find the value of x and y
Answer:
x = 8, y = 27
Step-by-step explanation:
Since both opposite lines are equal in length to each other, these opposite lines are parallel to each other. The top line is parallel and same length as the bottom line and the left and right lines are also parallel and equal in length.
Based on that, the two left side angles must equal 180 and the right side two angles must equal 180.
(2y + 24) + (3y + 21) = 180
That's the same as 2y + 24 + 3y + 21 = 180
Simplify to 5y + 45 = 180
Subtract 45 from both sides
5y = 135
y = 27
(16x - 26) + (9x + 6) = 180
16x - 26 + 9x + 6 = 180
25x - 20 = 180
25x = 200
x = 8

Write an absolute value equation of the form |ax+b|=cx+d that has no solution. Assume that a, b, c and d ≠0
Answer:
|x+1| = x - 1 has no solution.
Step-by-step explanation:
One interpretation of |x - a| is “the distance between the numbers x and a. So |x - b| = c means that the distance between x and b is equal to c . For this to have any solutions, we need c >= 0. When c >0 there will be exactly two solutions, one to the left of b and one to the right of b. When c = 0, the solution is unique: x = b. So, now you should be able to select the only values for b and c that produce the desired set of solutions.

Isaac wants to play miniature golf. Go Golf charges $2.50 for ball and club rental and $4.25 per game. Golf Games charges $3.25 for ball and club rental and $8.50 for two games. For how many games would the cost be the same? Write and solve an equation to determine the number of games for which the cost would be the same.
The cost would be the same for 47 Go golf and 54 golf games.
What is the Multiplication operation?In mathematics, Multiplication operations perform Multiplying values on either side of the operator.
Given data as:
Charges for Go Golf -
Renting a ball and a club costs $2.50.
$4.25 for one game and
Charges for Golf Games -
3.25 for the rental of a ball and a club
$8.50 for two games
We have to determine the number of games would the cost be the same.
Total charges of Go golf per game = $2.50 + $4.25 = $6.75
Total charges of Golf game for 2 games = $3.25 + $8.50 = $11.75
For per game = $11.75 / 2 = $5.875
Let the game would be x for Go golf and
And let game would be y for the golf game
As per the given condition,
6.75 x = 5.875y
27/4 x = 47/8 y
Apply cross multiplication operation,
54x = 47y
x/y = 47 / 54
x = 47
So y = 54.
Hence, the cost would be the same for 47 Go golf and 54 golf games.

The cost would be the same for 47 games at Go Golf and 54 games at Golf Games.
Total charges of Go golf per game = $2.50 + $4.25 = $6.75
Total charges of Golf game for 2 games = $3.25 + $8.50 = $11.75
Cost per game at Golf Games
= Total charges for 2 games / 2
= $11.75 / 2
= $5.875
Let the number of games be x for Go Golf and y for Golf Games.
As per the given condition,
6.75x = 5.875y
To find the relation between x and y, cross-multiplication can be used:
27/4 x = 47/8 y
54x = 47y
x/y = 47/54
Comparing the value gives
x = 47 and y = 54.
Hence, the cost would be the same for 47 games at Go Golf and 54 games at Golf Games.
