Answer: 50 + 39x(1) = y
32 + 45x(2) = y
Business A, because it is faster
Step-by-step explanation: from business A it is said they charge 50 for a service call plus an additional 39 per hour, so labelling x as number of hour we will get 39x then adding it to 50 to get the total amount of charge which is y, and I put (1) and (2) after x to differentiate the x for business A and B, applying the same explanation for business B we get the two equations
50 + 39x(1) = y
32 + 45x(2) = y
So the two equations equals to y, we equate both equations
50 + 39x(1) = 32 + 45x(2)
Now we assume that x(1) = 1
So
50 + 39(1) = 32 + 45x(2)
57 = 45x(2)
x(2) = 57/45
x(2) = 19/15
So since it's a time value, we make the denominator into 60
x(2) = 19/15 x 4/4
x(2) = 76/60 hour = 76 minutes = 1hour 16mintes
So this means that for every hour business A takes for the service call, business B takes an hour and 16minutes
So I will take business A because it is faster than business B
Average = Total/sample size
Total = 35800+47000
= 82800
Average = 82800/2
=$41400
Answer:
So to do this you need a protactor and measure it with it, then add the total
Step-by-step explanation:
For this case we have to:
Represents the solution of all strict minor numbers to -5.
Represents the solution of all strict major numbers to 5.
The global solution is given by the intersection of both sets. The symbol of intersection is denoted as: ∩
If we represent the solution in a numerical line, it gives us empty. do not intersect.
Answeer:
Empty set
Answer:
Step-by-step explanation:
you know the total angle is 180° from A to D
and you know that ∠BEC is 90°
also you are told that ∠CED is 18°
and that ∠AEB is 4x°
so just put that all together
180=90 + 18 +4x
now solve for X
180-90-18=4x
72=4x
18 = x
so now you know X
now solve ∠AEB
4(18) = 72°
∠AEB= 72°
