Im not 100% sure but, this is how I solved the problem. Just plug the coordinates into the equation. For example, (3,9) x=3 and y=9.
the equation is y=x*3 so 9=3*3 and 3*3=9 so that point is true. If you continue to do the same thing for all the point you should get F,C, and D
The question is -x/3 = 2 which is 1/3x=2
multiply both sides by 3, and you'll get x = 6
Answer:
Each Caramel Macchiato is $5.60
Step-by-step explanation:
You could write the equation 5x+7=35
x stands for the price of each macchiato
the +7 is the $7 left-over after getting 5 macchiatos.
Then solve the equation.
1) subtract 7 on both sides
5x=28
2) divide by 5 on both sides
x=5.60
Answer:
a) 0.1535
b) 0.4866
c) 0.8111
Step-by-step explanation:
The probability that the next call come within the next t minutes is:
According to this model,
a) the probability that a call in comes within 1/2 minutes is 
=0.1535
b) the probability that a call in comes within 2 minutes is 
=0.4866
c) the probability that a call in comes within 5 minutes is 
=0.8111
25
Step-by-step explanation
Let the ones's digit =x.
So, sum of the digits =7
Tens's digit =7−x
Original no. =10(7−x)+x=70−10x+x=70−9x
Reversed no. =10x+7−x=9x+7
2(orig no) = reversed no. −2
2(70−9x)=9x+7−2
140−18x=9x+5
27x=135
x=5
Ten's digit =7−5=2
No. =25
