James walks his dog every 3 days, Anna walks her dog every four days, if they both walk their dogs on a monday, on which day of the week will they walk their dogs together
Answers
Final answer:
James and Anna walk their dogs every 3 and 4 days respectively. The Least Common Multiple of 3 and 4 is 12, so they will walk their dogs together every 12 days. Since they walk their dogs on a Monday, they will walk them together on a Monday.
Explanation:
This question is about finding the Least Common Multiple (LCM) of two numbers. In this case, the two numbers are the days James and Anna walk their dogs: 3 days and 4 days. The LCM of 3 and 4 is 12. Therefore, James and Anna will walk their dogs together every 12 days.
If they both walk their dogs on a Monday, 12 days later will also be a Monday. So, they will walk their dogs together on the same day of the week, which is Monday.

Data we are looking for:
x - subscription plan
y - rate per minute
1. Finding the monthly fee (x) + rate per minute (y)
x + 150y = 45.50
x + 100y = 38.00
you have to deduct those equatations (x - x = 0, 150y - 100y = 50y, 45.5 - 38 = 7.5)
- finding rate per minute:
50y = 7.50
5y = 0.75
y = 0.15
- finding monthly fee
x + 150 *0.15 = 45.50
x = 45.50 - 22.50
x = 23.00
Looking at the data above you can see that no matter for how many minutes you use your phone you have to pay 23$. For every minute you spend talking the fee is 0.15$
That is why (z) the total amount you have to pay consist of 23 (subscription) + 0.15y (15c per minute):
z = 23 + 0.15y

Answer:
Step-by-step explanation:
We can make 2 simultaneous equations and solve for the set fee
and the per minute charge:
Let x = fixed monthly rate
Let m = per minute charge
x + 100m = 135 {equation 1}
x + 500m = 375 {equation 2}
subtract equation 1 from equation 2
400m = 240
m = 0.6
substitute that back into equation 1 or 2 to solve for x.
Using equation 1
x + 100(.6) = 135
x + 60 = 135
x = 75
The fixed monthly rate is $75
The per minute charge is $0.6
*****************************
If y is the total cost for a month and x is the
number of minutes used the equation is:
y = 0.6x + 75

Choose the correct answer below.
O A. The two triangles are congruent by SAS, not the HL Theorem.
O B. In AEFG, EF is a leg and in ADEG, DE is the hypotenuse, so they cannot be corresponding sides.
O C. The two triangles are congruent by SSS, not the HL Theorem.
OD. In AEFG, EG is a leg, and in ADEG, EG is the hypotenuse, so they cannot be corresponding sides.

The two triangles are congruent by SAS, not the HL theorem. Therefore, the correct answer is option A.
Triangle DEG and triangle EFG are right triangles.
The figure shows DE=EF (Given)
EG=EG by the reflexive property.
Therefore, by the HL theorem, Triangle DEG and triangle EFG are congruent.
Here, Mohamed stated postulate wrong.
By SAS postulate, Triangle DEG and triangle EFG are congruent.
Therefore, the correct answer is option A.
