Answer:
i think 6x
Step-by-step explanation:
cz we have a variable
The required cost is $ 101.22.
This problem can be solved by unitary method.
Given that monthly cost of customer if he uses 410 minutes is $71.
So, cost per minute =
=$ 0.17
And if the customer uses 720 minutes then the cost is $118.
So, cost per minute is =
=0.16
Now if he uses 687 minutes then for 410 minutes cost incurred will be
= 410 × 0.17
= $ 69.7
And for next 197 minutes cost incurred will be = 197 × 0.16
= $ 31.52
Total cost for 687 minutes = $(69.7 + 31.52)
= $ 101.22

Since it says the sum of any number not one in specific then the value will be x, plus the sum of 7,
Answer:
In fig. 9, angle Y = angle 110° (vertically opposite angles )
Angle x = angle z = 180 - 110 = 70° (angles on a straight line)
In fig 10, angle y = 78°
Angle x = angle z = 180-78 = 102°
In fig 11, angle x = 83°
Angle y = angle z = 180-83 = 97°
In fig 12, angle y = 37°
Angle x = angle z = 180-37 = 143°
If the top number the numerator is bigger than the denominator then you would have a fraction that can be turned into a mixed number.
if it is less then it is a fraction.
