Answer:
Step-by-step explanation:
let the number of dimes=x
and number of quarters=y
x=2y
0.10 x+0.25 y=2.25
or 10x+25y=225
divide by 5
2x+5y=45
2 ×2y+5y=45
4y+5y=45
9y=45
y=45/9=5
x=2y=2×5=10
Hence dimes=10
quarters=5
Yu add the products of the two numbers by 7
Answer:
4n ≤ 32
/4 /4
n ≤ 8, he could run less than 8 or just 8 laps,
so possible laps:
1, 2, 3, 4, 5, 6, 7, or 8 laps he could've ran.
Answer:
square root property
Step-by-step explanation:

Step-by-step explanation:
6 * 1 = 6

so,
360° / 6 = 60° (Central angle for each arc)
