Answer:
Step-by-step explanation:
a and s are the numbers of adult and student tickets, respectively.
9a + 14s = 220
11a + 7s = 188 Multiply by -2 and add to first equation.
-22a - 14s = -376
9a + 14s = 220
-----------------------
-13a = -156
a = 12
9(12) + 14s = 220
14s = 112
s = 8
Adult tickets cost $12. Student tickets cost $8.

2x – 6у = 2. Solve the equations by using elimination (adding) show work
Answer:
Step-by-step explanation:
3x - 3y = -3
2x - 6y = 2
-6x + 6y = 6
2x - 6y = 2
-4x = 8
x = -2
-4 - 6y = 2
-6y = 6
y = -1

What is 9.52 rounded to the nearest tenth?
o 9.0
9.5
o 9.6
O 10.0
I need this fast
Answer:
9.5
Step-by-step explanation:
When rounding to the nearest tenth, check to see what the hundredths place value is.
If it is 0.05 or greater, we will round the tenths place up one.
If not, the tenths place will remain the same.
Since 9.52 has a hundredths place value of 0.02, we will keep the same tenths place value.
So, the correct answer is 9.5
If you subtract 14 from twice a number, the result is 6. What is the number?
The equation for this statement:
2x – 14 = 6
=> 2x = 6 + 14
=> 2x = 20
=> x = 20/2
=> x = 10

Jennie charges $200 per passenger for a sunset sailing
tour on her catamaran, while Paul charges $250 per
passenger. We can define the amount of money each
person earns per cruise as a random variable.
Let A = the amount of money Jennie earns and let B =
the amount of money Paul earns.
What is the mean of the sum and the mean of the
difference of the amount of money that Jennie and
Paul earn on a randomly selected cruise?
MA+B= $
HA-B = $
A = 200X and B = 250Y

-232.5
272.687
1692.5
Answer:
1692.5 and -232.5
Step-by-step explanation:
The mean of the sum would be as follows:
1692.5
The difference of the amount of money earned by Jennie and Paul would be:
-232.5
Mean
Given that,
Money earned by Jennie(A) [tex]= 200X[/tex]
Money earned by Paul(B) [tex]= 250Y[/tex]
μ[tex]_{A}[/tex] = $[tex]730[/tex] & σ[tex]_{A}[/tex] = $ [tex]192.62[/tex]
μ[tex]_{B}[/tex] [tex]=[/tex] $[tex]962.5[/tex] & σ[tex]_{B}[/tex] [tex]=[/tex] $ [tex]253.425[/tex]
So,
The mean of the sum [tex]= 1692.5[/tex]
The difference of the amount of money [tex]= -232.5[/tex]

What is x/3 + x/5 ? Give the correct answer
Answer:
[tex]\dfrac{x}{3}+\dfrac{x}{5}[/tex] =
Step-by-step explanation:
We need to find the value of [tex]\dfrac{x}{3}+\dfrac{x}{5}[/tex]
The LCM of 3 and 5 is 15. So,
[tex]\dfrac{x}{3}+\dfrac{x}{5}=\dfrac{5x+3x}{15}[/tex]
[tex]=\dfrac{8x}{15}[/tex]
So, the value of [tex]\dfrac{x}{3}+\dfrac{x}{5}[/tex] is equal to [tex]\dfrac{8x}{15}[/tex].
What is a probability that rolling a six-sided die results in 2 or 3?
The probability of rolling a 2 would be 1/6
The probability of rolling a 3 would be 1/6
The probability of rolling a 2 or a 3 would be 1/6 + 1/6 = 2/6, which reduces to 1/3
The answer is 1/3

The value of a baseball card can be represented by the equation Y - 3x+ 39, where x represents the number of year
that Robert has owned the card and y represents the total value, in dollars, of the card. What was the value of the card when Robert originally purchased it?
$3
$13
$36
$39
9514 1404 393
Answer:
$39
Step-by-step explanation:
Assuming your equation is supposed to be ...
y = 3x +39
The value of y when x = 0 is 39.
The value of the card when Robert purchased it was $39.
Answer: $39
Step-by-step explanation:

Step 1: Define Systems
y = 2x + 1
x + 3y = 10
Step 2: Solve for x
Substitution
Substitute in y: x + 3(2x + 1) = 10Distribute 3: x + 6x + 3 = 10Combine like terms: 7x + 3 = 10[Subtraction Property of Equality] Subtract 3 on both sides: 7x = 7[Division Property of Equality] Divide 7 on both sides: x = 1Step 3: Solve for y
Define original equation: y = 2x + 1Substitute in x: y = 2(1) + 1Multiply: y = 2 + 1Add: y = 3Step 4: Find difference
y = 3
x = 1
Subtract: 3 - 1 = 2Solve for y. Thank you.

Marcus wants to save $378 in order to buy a new electronic keyboard. He plans to save $15.75 every week from his paycheck. Right and solve an equation to find how many weeks Marcus will need to save save.
Answer:
15.75 * 24 = 378
Step-by-step explanation:
15.75x = 378. We need to first isolate the variable. x = 24. Using this we can make the equation. 15.75 * 24 = 378

Answer:
x=25
Step-by-step explanation:
Answer:
x = 25
Step-by-step explanation:

m =
Answer:
3/5
Step-by-step explanation:
As we move (right) from the first point to the second, we see x (the run) increasing by 10 and y (the rise) by 6. Thus, the slope of the line shown in the diagram is
m = rise / run = 6/10 = 3/5

Solve for x. Round to the nearest tenth if necessary.
Answer:
x = 19
Step-by-step explanation:
Since, both the triangles (small and large) given in the picture are similar,
Their corresponding sides will be in the same ratio.
By applying this property,
[tex]\frac{20}{36}= \frac{30}{30+(x+5)}[/tex]
[tex]\frac{5}{9}= \frac{30}{x+35}[/tex]
5(x + 35) = 9 × 30
5x + 175 = 270
5x = 270 - 175
5x = 95
x = [tex]\frac{95}{5}[/tex]
x = 19

How many 1/12 make a quarter?
Answer:
3
Step-by-step explanation:
3/12 = .25
.25 = a quarter
plz mark brainliest ! :)
Answer:
3
Step-by-step explanation:
Let the number of 1/12 that make a quarter be x.
x * 1/12 = 1/4
Multiply both sides by 12.
x * 1/12 * 12 = 1/4 * 12
x = 3
