Simplify each expression (5p - 3)+(2p2 - 3p)

the answer is 2p^2+2p−3

Step-by-step explanation:

1. Combine Like Terms: these are 5p and 3p

2. which gives us 2p

3. Always put the squared first and the constant (without any variable last)

which makes 2p^2+2p-3

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
