If a number’s composite form is 343, which of the following shows its exponential form as a product of prime numbers? a.7 · 49 b.73 c.49 d.343

a is the answer

Step-by-step explanation:

7×7×7=343

7×7=49

49×7=343

b 1: 45 am

step-by-step explanation:

its that because if it was in the pm it would be 1345

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
