Inequalities
Chua pays a monthly fee of $25 for his phone service, plus $0.05 per minute of use.
Let M = number of minutes Chua uses the phone service.
His monthly cost for the phone service is:
C = 25 + 0.05M
The least he has been charged in a month is $89.40. If we want to know the number of minutes he used the service in that month, then we must solve the inequality:
25 + 0.05M ≥ 89.40
Subtracting 25:
0.05M ≥ 89.40 - 25
Operating:
0.05M ≥ 64.40
Dividing by 0.05:
M ≥ 64.40 / 0.05
M ≥ 1288
He has used his phone service at least for 1288 minutes in a month
Answer:
B
Step-by-step explanation:
make sure calculator is in degrees mode and insert equation to get -7.5
300.50(0.07)= 21.04
300.50+21.04= 321.54 321.54x = 900.85 x = 2.8
Add up all the amounts of marbles, which gives you 52, then see how many greens ones there are.
So the answer would be 10/52
Answer:
lenght: 192
Width 128
Height: 64
Step-by-step explanation
if every other thing is times height then height is x so you would do x+2x+3x = 384 and solve from there to get 384/6x= 64
and since width is 2 times that then 64 times 2 is 128 and times 3 is the lenght
