Answer:
3
Step-by-step explanation:
one day is 24 hours which is 2 times 12, so in two days there are 4 12-hour so divide 48 by two four times:
48/2=24
24/2=12
12/2=6
6/2=3
The correct answer is 3.25
Answer:
1st solution is -2x+12
2nd solution is 5x+31
3rd one doesnt have a solution
Step-by-step explanation:
Answer:
C 70.26 in2
Step-by-step explanation:
6 = D
R = D/2
R = 3
A = 3.14 x 3 x 3
A = 3.14 x 9
A = 28.26
The area of the triangle is
A = 6 x 7
A = 42
So
42 + 28.26
70.26 in2
Let f= number of five cent stamps
let t=number of ten cent stamps
total spent is 5f+10t=100
total stamps bought is f+t=13
5f+10t=100
f+t=13
f=13-t
5(13-t)+10t=100
65-5t+10t=100
5t=35
t=7
f+t=13
f+7=13
f=6
6 five cent stamps and 7 ten cent stamps
