Answer:
Number 1 and 4
Step-by-step explanation:
To do this substitute the different values of x and y into the equations and see if they come out true or not.
1. (4, -3)
Put x = 4 and y = -3 into both equations:
2x + y = 5 --> 2(4) - 3 = 5 --> 8 - 3 = 5 --> 5=5 (true)
6x + 3y = 15 --> 6(4) + 3(-3) = 15 --> 24 - 9 = 15 --> 15 = 15 (true
So number 1 works
2. (2, 4)
Put x = 2 and y = 4 into both equations:
2x + y = 5 --> 2(2) + 4 = 5 --> 4 + 4 = 5 --> 8 = 5 (NOT true)
Number 2 does not work
3. (1, 3)
Put x = 1 and y = 3 into both equations:
2x + y = 5 --> 2(1) + 3 = 5 --> 2+ 3 = 5 --> 5 = 5 (true)
6x + 3y = 15 --> 6(1) + 3(9) = 15 --> 6 + 27 = 15 --> 33 = 15 (not true)
Number 3 does not work
4. (0, 5)
Put x = 0 and y = 5 into both equations:
2x + y = 5 --> 2(0) + 5 = 5 --> 5 = 5 (true)
6x + 3y = 15 --> 6(0) + 3(5) = 15 --> 15 = 15 (true)
Number 4 does work
Number 1 and number 4 are the answers.
Samantha's college runs on a trimester schedule so she receives a bill 3 times a year for tuition. Each trimester costs 1,450 and Samantha must complete 2 years of college to receive degree. The average costs for books each trimester is 350$. Approximately what will be the total cost of Samantha to get her degree?
Answer:
$89100
Step-by-step explanation:
Given data
Each trimester costs=$1,450
time taken to complete degree= 2 years
In 1 years, she will pay = 14500*3= $43500
In 1 years, she will pay =$43500*2= $87000 in tuition
The average costs for books each trimester is 350$
In 1 years, she will pay = 350*3= $1050
In 1 years, she will pay =$1050*2= $2100 for books
In all she will pay
87000+2100=$89100

The rate of sales tax on trousers is 10%. One can buy a pair of trousers at $ 660. What is the marked price?
Answer: $600
Step-by-step explanation:
The marked price is the price of the trouser without a sales tax.
The sales tax is 10% which means it increased the marked price by 10% to get to $660.
Assume that price is x:
660 = (1 + 10%) * x
x = 660/(1 + 10%)
x = $600

Thomas bought a new backpack that was 30 off the original price.The sale resulted in a $15 discount.What was the original price of the backpack?
Answer:
30% = $15
1% = $15 ÷ 30 = $0.50
100% = $0.50 x 100 = $50
$50
A town's total allocation for firefighters’ wages and benefits in a new budget is $600,000. If wages are calculated at $40,000 per firefighter and benefits at $20,000 per firefighter, write an equation whose solution is the number of firefighters the town can employ if they spend their whole budget. Solve the equation
Answer:
10
Step-by-step explanation:
budget (b) = 600,000
cost per firefighter (c) = 40,000+20,000 = 60,000
total amount of firefighters (t) = b/c
t = 600,000/60,000 = 10
______________________________
N = NumberB = BudgetBPP = Budget Per PersonN = B ÷ BPP= $600,000 ÷ $60,000= 10 Firefighters______________________________

Tyler used 114 gallons of paint to paint 47 of a fence. How many gallons will it take to paint the whole fence?
Answer: It will take 199.5 gallons to paint the whole fence.
Step-by-step explanation:
Given: Paint required to paint [tex]\dfrac47[/tex]of fence = 114 gallons
Then , paint required to paint whole fence = [tex]114\div\dfrac47[/tex]
i.e. paint required to paint whole fence = [tex]114\times\dfrac{7}{4}[/tex]
i.e. Paint required to paint whole fence= 199.5 gallons
Hence, it will take 199.5 gallons to paint the whole fence.

A)20/21
B) 20/29
C) 21/20
D)21/29
Answer:
B) 20/29
Step-by-step explanation:
Sin(a) is equal to opposite side length divided by hypotenuse.
Answer question one and show work.
Answer:
x = 28
Step-by-step explanation:
angle 1 and angle 2 are complementary (their sum is 90°)
x + 5 + 2x + 1 = 90 add like terms
3x + 6 = 90 subtract 6 from both sides
3x = 84 divide both sides by 3
x = 28
Howie bought 4 binder for $2.14 each, a pack of pencils for $1.25, and a new coat for $19.95. How much money did Howie spend altogether? A. $23.34 B. $27.34 C. $28.66 D.$29.76
Answer:
A. $23.34
Step-by-step explanation:
The computation of the amount of money spend altogether is given below:
= Purchase price of 4 binder + pack of pencils + new coat
= $2.14 + $1.25 + $19.94
= $23.34
We simply added the above three cost so that the total money incurred would be come
Hence, the correct option is A
Please please help me please
Answer:
6.09
Step-by-step explanation:
With reference angle 29°
hypotenuse (h) = 7
base (b) = x
Now
cos 29° = b / h
0.87 = x / 7
x = 0.87 * 7
x = 6.09

5x-2x = 7
x+y=7
Answer:
x= 7/3, y= 14/3
Step-by-step explanation:
5x-2x=7
x+y=7
Evaluate 5x-2x=7
5x-2x=3x
3x=7
divide both sides by 3
x=7/3
plug the x value into the second equation
7/3+y=7
subtract 7/3 from both sides
y=7-7/3
evaluate
21/3-7/3=14/3
x= 7/3, y= 14/3

Answer: Zero slope.
Step-by-step explanation: The line does not increase or decrease, so your two options are undefined or zero. If the line were vertical (up and down), the slope would be undefined since there would be many y-values for one x-value. Since the line is horizontal (right to left), though, each x-value only has one y-value. Since the y-value doesn’t change, the slope is zero.

In a two digit number, the tens digit is 2 less than the units digit multiplied by 3. The reversed number is half of the original number plus 1/2. What is the original number?
Answer:
73
Step-by-step explanation:
Original number: XY
x = 3y - 2
10y + x = (10x + y) / 2 + 1/2
substitution: 10y + 3y - 2 = 13y - 2 = (10 * (3y - 2) + y) / 2 + 1/2
* 2 both sides and simplify: 26y - 4 = 31y - 19
31y - 26y = -4 + 19
5y = 15
y = 3
x = 7
Original number: 73
