The answer is C because is n is positive and even it will only open up.
F=m+25
m+f=139, using f from above we have:
m+(m+25)=139
2m+25=139
2m=114
m=57, and since f=m+25
f=82
So there are 57 males and 82 females.
Answer:
The answer would be B: 8 ones, 4 tenths, and 5 hundredths.
Explanation:
First, you would have to use the equation: 1.57 + 6.88 = ?
Do the math, and 1.57 + 6.88 = 8.45
Now look at the answer choices. You can automatically get rid of every answer choice but B because none of them have an 8 in the ones place.
2a+1b=27.50
4a+2b=59.50
Multiply first equation by -4 and the second by 2 so you can drop off the a values then add the equations together. Then solve for b. You should get b=6.
Then plug b into one of the original equations and solve for a and you should get 10.75
So a plate of spaghetti is $10.75 and a salad is $6.

Answer:
12000-14000 (in miles)
Step-by-step explanation:
We are given that the annual cost of driving a certain car is given by the formula

Where m=Represents the number of miles driven per year
C=Cost in dollars
We have to find the range of miles that Jane can drive her new car.
Range of budgets=$7040-$7780
Substitute C=$7040 in the given formula





Substitute C=$7780 in the given formula




The range of miles that Jane can drive her new car=12000-14000
