Answer:
Well, 100 km equals approximately 63 miles.
Step-by-step explanation:
One mile is approximately 1.6 km, so you just divide 100 km by 1.6 and you should get the miles, being 62.5 miles, or 63.
T = 4 + 2A
S = 5A - 8
T = S
Since T and S are equal, set them against each other
2A + 4 = 5A - 8
Subtract 2A from each side, and add 8 to each side
12 = 3A
Divide each side by 3
A = 4
So Andrew is 4 years old
If Andrew is 4, then Tom is twice that plus 4, or 12. Sarah is 5 times 4 less 8, or 12.
Answer:
20/8 and 45/18
Step-by-step explanation:
Set each fraction up with the proportion 10/4 and cross multiply to see if there products are equal.
E.x 20/8
10/4=20/8 then cross multiply
10×8=80 and 20×4=80
80=80
Another one is 45/18.
10/4=45/18
10×18=180 45×4=180
180=180
