Cuanto es -4 x -10 < 2 ?

-400

Step-by-step explanation:

Use Order of Operations. (PEMDAS)

In this expression we see exponents first. -10 ^ 2 = -10 * -10 = 100

Then, there is multiplication. -4 * 100 = -400

That is your answer.

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
