What is the actual distance of 9 cm on a map whose scale shows that 3 cm = 5 km? A) 15 km
B) 12 km
C) 18 km
D) 21 km

Step-by-step explanation:

→ Write out the scale

3 cm = 5 km

→ Multiply everything by 3 to get 9 cm on the left side

9 cm = 15 km

x + y = 90 5x – 10y = 90 90 – 10y = 5x 90 + 10y = 5x

step-by-step explanation:

last month maria hiked the 5-mile mountain trail a number of times and she hiked the 10-mile canal trail several times. let x represent the number of times she hiked the 5-mile trail, and let y represent the number of times she hiked the 10-mile trail. if she hiked a total of 90 miles, which equation can be used to find the number of times maria hiked each trail? x + y = 90 5x – 10y = 90 90 – 10y = 5x 90 + 10y = 5x

15% chance.

step-by-step explanation:

3/10 times, the 5 year old will get a tablet. 5/10 times, the 13 yer old will get a tablet. multiply both fractions to get 15/100 times, both would have a tablet.
