Step-by-step explanation:
On the first day of ticket sales the school sold 3 adult ticket and 8 student tickets for a total of $72. The school took in $152 on the second day by selling 7 adult tickets and 16 student tickets. How much is a student ticket?
Day 1: 3x + 7y = 72
Day 2: 7x + 16y = 152
This becomes a system of equations.
3x+8y=72
3x+8y+−8y=72+−8y (Add -8y to both sides)
3x=−8y+72
3x/3 = −(8y+72)/3
X = (-8/3) y + 24
Substitute (-8/3) y + 24 for x in7x+16y=152:
7(-8/3 y + 24) + 16y = 152
-8/3 y + 168 = 152 (Simplify both sides of the equation)
-8/3 y + 168 − 168 = 152 + (−168) (Add -168 to both sides)
-8/3 y = -16
(-8/3 y)/(-8/3 y) = -16/ -8/3 y (Divide both sides by (-8)/3)
y = 6
which expression is equivalent to the given expression?
Answer:
4ln x +ln 3-lnx
4ln x -ln x+ln3
3ln x+ln 3
ln(3x+3)is equivalent.

a cyclist covers a distance of 15km in 2hours calculate his speed
Answer:
7.5km/h
Step-by-step explanation:
Given data
Distance= 15km
Time = 2 hours
We know that the expression for the speed is
Speed= distance/time
Substitute
Speed= 15/2
Speed= 7.5 km per hour
Hence the speed is 7.5km/h

If you want to bowl six games which ally is better show work
Answer:
Pinz
Step-by-step explanation:
So to set up the equation for Lanez:
y = 3.5 + 4.25x
Next we compare the prices for both overall by plugging 6 games in as x:
Lanez:
y = 3.5 + 4.25(6)
y = 3.5 + 25.5
y = 29
Pinz:
y = 3.75 + 4(6)
y = 3.75 + 24
y = 27.75
29>27.75
Lanez is more expensive with it costing $29 for a night as opposed to the $27.75 one would pay to play at Pinz.
Sheryl has a recipe for pasta with

130 and then twice as much pasta, 130+130=260
Then add the vegetables: 130+260=390
390 is the total mass in grams
the area of a Trapezium is 132 cm². Its height is 14 cm the larger parallel side is longer than the other by 16 cm. find the length of the parallel side. Please someone help!!
1/2 (a+b)h
1/2 (a+16)14=132
8×14=112
14÷2=7
132-112=20
20÷7 =2.857142857

Emily has 6 gallons of water josh has 23 quarts of water. How many more points does Emily have more than josh
Answer:
2 pints
Step-by-step explanation:
To determine the amount of pints that Emily has more than Josh, gallons and quarts have to be converted to pints and the value is then subtracted
1. Convert gallons and quarts to pints
1 gallon = 8 pints
6 gallons = 8 x 6 = 48 pints
1 quart = 2 pints
23 quarts = 2 x 23 = 46 pints
2. Determine the difference in the amount of pints Emily has and the amount Josh has
48 pints - 46 pints = 2 pints

Members of a baseball team raised $1479.25 to go to a tournament. They rented a bus for $800.50 and budgeted $45.25 per player for meals. Write and solve an equation which can be used to determine pp, the number of players the team can bring to the tournament.
Answer:
15 players
Step-by-step explanation:
First, you might want to exclude out how much it cost to rent a bus.
1479.25 - 800.50 = 678.75
After that, the remaining amount of money is how much money is spent altogether for the basketball player's meal, since each player had the same budget for the meal, it made the question easier.
678.75 ÷ 45.25 = 15
a) BCD is a straight line.
Triangle ABC is equilateral.
CE = DE
E
Not drawn
accurately
А
320
B
С
Work out the size of angle x.
(4)
Answer:
x = 46°
Step-by-step explanation:
Since Δ ABC is equilateral then interior angles = 60°
Since CE = DE then Δ CDE is isosceles and the base angles are congruent, so
∠ ECD = [tex]\frac{180-32}{2}[/tex] = [tex]\frac{148}{2}[/tex] = 74°
BCD is a straight line, then the 3 angles on it sum to 180°, that is
60° + 74° + x = 180°
134° + x = 180° ( subtract 134° from both sides )
x = 46°
108 divided by 2 1/2
Answer:
43.2
Step-by-step explanation:
first turn 2 1/2 into an improper fraction
(2 × 2) + 1 = 5
5/2
then turn 5/2 into a fraction
5 ÷ 2 = 2.5
now divide!
108 ÷ 2.5 = 43.2
Number equivalent to 108/2 1/2 is 43.2 .
Given,
108 divided 2 1/2
Using division property,
The rules for division are:
(1) positive × or ÷ positive = positive
(2) positive × or ÷ negative = negative
(3) negative × or ÷ negative = positive
Rule for long division method,
Divide the tens column dividend by the divisor.
Multiply the divisor by the quotient in the tens place column.
Subtract the product from the divisor.
Bring down the dividend in the ones column and repeat.
Therefore,
divide, multiply, subtract, bring down and repeat or find the remainder.
Here the required value is of :
108/2 1/2
= 108 / (5/2)
= 43.2
Hence the answer is 43.2
