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

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
Two light houses flash their lights every 20 and 30 seconds respectively. Given that they flash together at 8:00 PM. At what time will they next flash together?
Answer:
They will flash together at;
8:01 PM
Step-by-step explanation:
Here, we want to
calculate the time at which they would both flash together
What we have to do here is to calculate the lowest common multiple of 20
and 30 seconds
Mathematically, we have this as;
60 seconds
60 seconds is the same as 1 minute
So the time they will flash together is 8:01 PM

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

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.

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
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 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______________________________
