On-the-Go Phone Company has two monthly plans for their customers. The EZ Pay Plan costs $0.15 per minute. The 40 to Go Plan costs $40 per month plus $0.05 per minute. Which plan should you choose if you want only 200 minutes per month? Why? Justify your answer.
Answer:
The EZ Pay Plan because it would cost less than the 40 to Go Plan.
Step-by-step explanation:
You will have to calculate the amount that you would pay with each monthly plan if you have 200 minutes per month.
-EZ Pay Plan:
$0.15*200=$30
-40 to Go Plan:
$40+($0.05*200)=$40+$10=$50
According to this, the answer is that if you only want 200 minutes per month, you should choose the EZ Pay Plan because it would cost $30 which is less than the 40 to Go Plan that would cost $50.

Answer:
1 of 8: (729, 81, 9, 1)
2 of 8: 1 = (-1)^0 = 2^0
3 of 8: 1
Step-by-step explanation:
The basic rule is that any non-zero value to the zero power is 1. It doesn't matter whether the value is positive or negative. Raising it to the zero power makes it 1.
So, for question 2 of 8, the two equivalent expressions can be anything raised to the zero power (or anything with a value of 1, for that matter).

5(3x+8)=175
with steps pls
Answer:
x=9
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
5(3x+8)=175
(5)(3x)+(5)(8)=175(Distribute)
15x+40=175
Step 2: Subtract 40 from both sides.
15x+40−40=175−40
15x=135
Step 3: Divide both sides by 15.
15x/15=135/15
x=9

*PLEASE HURRY* WILL GIVE BRAINLIEST* Write the equation in the form ax^2 + bx+c=0 where a > 0, if necessary. Then identify the values of a, b, and c. Do not actually solve the equation
3x^2 = 4x + 8
Answer:
a= 3
b=-4
c=-8
Step-by-step explanation:
3x²=4x+8
since the 4X is positive it will cross the equal sign and become negative and the same goes for 8,and this will leave nothing on the right of the equal sign therefore it will become 0
3x²-4x- 8= 0
the above equation is now in the form required
ax²+bx+c=0
so substitute the values according and u will see that a= 3
b=-4 and c=-8
hope this helps

Answer:
X= -11
Step-by-step explanation:
Combine the two equations to equal a supplementary line
(X+91)=(x+111)=180
Solve for x by reversing the equation
(x)+(x)=(180-91)+(-111)
x=-22/2
x=-11
