Answer:
Student tickets: 287
Adult tickets: 134
Step-by-step explanation:
Students: x
Adults: y
a) x + y = 421
b) 2x + 5y = 1,244
a) x = 421 - y
b) 2 (421 - y) + 5y = 1,244 (substitution)
842 - 2y + 5y = 1244
3y = 1244 - 842
y = 402/3
y = 134 adult tickets
421 - 134 = 287 student tickets
At 12 noon if the temperature is 38°C and if it decreases at the rate of 2°C per hour, then what would be the temperature at 5pm?
Answer:
38-2(5) = 28
So the temperature would be 28 degrees celsius
Answer: Teperature at 5PM will be 28°C
Ok so at 12 its 38°C
And it dcreases at 2°C an hour, we need to find the teperature at 5 o clock.
The number of hours between 12 and 5 mutiplied by 2 will give us the trail in temperature and then subtracting the trail i temperature witht the temperature a 12 will give us the teperature at 5 o clock.
SO,
hours between 12 PM and 5 PM is 5 hours
As, the temperature decreases at a uniform rate of 2°c per hour
⇒5×2°C
⇒10°C
Now the temperature at 5 PM will be 38°C-10°C=28°C

Answer:
a. 2x +y = 10; 2x +3y = 22
b. 6 minutes
Step-by-step explanation:
a) The problem statement tells you that ...
x = minutes around the block
y = minutes around the park
2x +y = 10 . . . . twice around the block and once around the park: 10 min
2x +3y = 22 . . . twice around the block and 3 times around the park: 22 min
__
b) Subtracting the first equation from the second gives ...
(2x +3y) -(2x +y) = (22) -(10)
2y = 12 . . . . . . . . simplify
y = 6 . . . . . . . . . divide by 2
It takes you 6 minutes to jog around the park.
Answer:
Part A) The system of equations is
[tex]2x+y=10[/tex]
[tex]2x+3y=22[/tex]
Part B) The number of minutes it takes you to jog around the park is [tex]6[/tex] mins
Explanation:
Part A) Write a system of linear equations
Let [tex]x[/tex] ----> the number of minutes it takes you to jog around the block
Let [tex]y[/tex] ----> the number of minutes it takes you to jog around the park
we know that [tex]2x+y=10[/tex] ----> equation A
and [tex]2x+3y=22[/tex] ----> equation B
Part B) How long does it take you to jog around the park?
Multiply equation A by [tex]-1[/tex] both sides
[tex]-1(2x+y)=-10[/tex] ----> [tex]-2x-y=-10[/tex] ----> equation C
Adds equation B and equation C
[tex]2x+3y=22[/tex]

Write an equality and then solve it. Sonya is a waitress. She earns $200 a week plus 15% tip in the cost of each meal she serves. What is the least amount of the total cost of the meals she serves in order for her to earn at least $450 each week. Answer this seriously or you’ll be reported
Answer:
$1666.67
Step-by-step explanation:
$450 is the total amount she earned and $200 is the weekly wage she received. That means that $250 came from tips.
$200 + .15 (x) = 450
.15x=250
x=$1666.67

(b) it takes 44 pounds of seed to completely plant an 8
-acre field.
How many pounds of seed are needed per acre?
pounds per acre
Check
Answer:
5 pounds and 8 ounces of seed per one acre.
Step-by-step explanation:
We have our two values, 44 pounds and 8 acres.
It also says it takes 44 pounds of seed for every 8 acres of farmland.
So to get the value of how much seed per one acre we need, we divide 44 by 8.
Doing so yields us 5.5 pounds, which can be converted to 5 pounds and 8 ounces. (remember 16 ounces is 1 pound)
1) 0.0 + 5.5 = 5.5
2) 5.5 + 5.5 = 11.0
3) 11.0 + 5.5 = 16.5
4) 16.5 + 5.5 = 22.0
5) 22.0 + 5.5 = 27.5
6) 27.5 + 5.5 = 33.0
7) 33.0 + 5.5 = 38.5
8) 38.5 + 5.5 = 44.0
Airfare from Atlanta,GA to Nashville,TN was decreased from $250 to $180.By what percentage did the cost of the airfare change?
Answer:
percentage cost of airfare change= (difference in cost / original cost )×100
% age = (250-180/ 250) ×100
=70/250 ×100
7000/250

In a piggy bank on his dresser, Tom has a total of $2.85 in pennies and quarters. If
the number of pennies is 5 more than three times the number of quarters, how
many pennies and quarters does he have in his piggy bank?
Number of pennies in piggy bank will be 35.
Number of quarters in piggy bank will be 10.
What is linear expression?
A linear expression is an algebraic statement where each term is either a constant or a variable raised to the first power.
Given that;
Total cost in piggy bank with pennies and quarters = $2.85
And, The number of pennies is 5 more than three times the number of quarters.
Let Number of quarters = x
And, Number of pennies = y
= 5 + 3x
Since, Total cost in piggy bank with pennies and quarters = $2.85
So, we can formulate;
0.25x + 0.01y = $2.85
Substitute the value of y as;
0.25x + 0.01(5 + 3x) = 2.85
0.25x + 0.05 + 0.03x = 2.85
0.28x + 0.05 = 2.85
x = 10
And, y = 5 + 3x = 5 + 3 × 10 = 35
Thus,
Number of pennies in piggy bank will be 35.
Number of quarters in piggy bank will be 10.

Is (1,-4) a solution to the equation y=-2/?
A yes
В. no
Answer: B.no
Step-by-step explanation:
To figure this out, plug (1, -4) into the equation y=-2x. 1 is the x value, so we plug it into the x. -4 is the y value, so we plug it into the y spot. In the end we get -4=-2(1). Is this true? No, it isn't. Therefore it is not an answer
