$70 = 270 min
x = 1260 min
Where x is the charge of phone service per 1260 min.
Cross multiply:
1260 * 70 = 270 * x
88200 = 270x
88200/270 = x
x = 326.67
The total charge of cellular phone service for 1260 min is $326.67
Answer:
A. No solution
Step-by-step explanation:
The given equation is 4(2 x + 9) = 4(2 x +6)
We divide through by 4 to get:
2 x + 9 = 2 x +6
We now group similar terms to obtain:


This final statement is false.
Therefore the given equation has no solution.
Answer:
1/15
Step-by-step explanation:
2/6 for the first one the first the second is 1/5, so 2/6=1/3, so 1/3 x 1/5 = 1/15 your answer is 1/15
First set everything to 0.

Giving you A= 1 , B= 1 and C= -5
Then input everything into the quadratic formula and either solve by hand or use a calculator.
Note exact values are found by hand, decimals are found using a calculator.
Question:
The circumference of a clock is 22 inches. What is the radius of the clock?
Answer:
Radius = 3.5 inches
Solution:
Shape of the clock is circle.
Circumference of the circle = 2πr
Circumference of a clock = 22 inches





⇒ r = 3.5 inches
Hence the radius of the clock is 3.5 inches.
