Answer:
Step-by-step explanation:
I think your question is to write WRITE A SYSTEM OF EQUATIONS in that situation.
And here is my answer:
- Let m - the number of minutes
1. The first choice is to pay $10.00 per month plus &0.09 per MB of data
<=> y = 0.09m + 10
2. The second choice is to pay $16.00 per month plus $0.07 per MB of data
<=> y = 0.07m + 16
So the system of equation is:
Hope it will find you well.
Answer:
She has 23 nickles and 5 dimes.
Step-by-step explanation:
Let n = the number of nickles and d = the number of dimes.
The number of each = 28. Set up the equation:
n + d = 28
Solve for n:
n = 28 - d
The total amount is $1.65 or 165 cents:
5n + 10d = 165
Substitute:
5(28 - d) + 10d = 165
140 - 5d + 10d = 165
140 + 5d = 165
5d = 165 - 140
5d = 25
d = 5, the number of dimes.
Solve for n:
n = 28 - d
n = 28 - 5 = 23, the number of nickles.
Proof:
5n + 10d = 165
5(23) + 10(5) = 165
115 + 50 = 165
165 = 165

Answer:
5:8, 25:1
Step-by-step explanation:
i guess this is ans
Circle Area = PI*r^2
Semi Circle Area = (PI*r^2)/2
76.97 = (PI*r^2)/2
76.97 * 2 / PI = radius^2
radius^2 = 76.97 * 2 / PI
radius^2 = 153.94 / PI
radius^2 = 49
radius = 7
Diameter = 14 yards
