Answer: B) a + c = 10
8a + 5c = 59
Step-by-step explanation:
We know that 10 total people went, so the first equation has to be equal to 10. The total was $59, so the second equation should be set equal to $59. Now that the second equation is for cost, we must make it 8a + 5c to represent the cost of the adult and child tickets which are $8 and $5, respectively.
Answer:
24 Bricks.
Step-by-step explanation:
We know the radius is 6 feet and that the diameter is twice that.
We also know the radius is 12 'bricks' in length.
If we divide both numbers by 12, we get that 1 'brick' is half a foot.
Since that's the radius and we want the diameter, we multiply the radius by 2 to get the diameter.
This results in 12 feet, or 24 'bricks'.
You need one equation for the physical nickels and dimes, which total to 21:
n+d=21
Secondly, you need one equation for the numerical value of those nickels and dimes. We know nickels are worth $0.05 and dime are worth $0.10:
.05n+.1d=1.70
Answer:
60
Step-by-step explanation:
let X be the total number of students.
48÷x *100 = 80
4800= 80x
X = 60 students
