Alicia cash half of a paycheck and set aside the other half to take her friends at a dinner. She spent $42 and 50 Cent on dinner and brought home more than $20. write an inequality to represent the situation, using X to represent the amount of a Alicia’s paycheck.

4a. is 3 miles every hour

4b. is 1/3 of an hour per mile

step-by-step explanation:

is there a question here?

step-by-step explanation:

7.9m and 4.3°

step-by-step explanation:

let east be +x and north be +y, x = distance * cos θ, y = distance * sin θ  

for 3.5 south, y = -3.5  

for 8.2, x = 8.2 * cos 30 and y = 8.2 * sin 30  

for 15 west, x = -15  

total x = 8.2 * cos 30 – 15 ≈ -7.9  

total y = -3.5 + 8.2 * sin 30 = 0.6  

magnitude = [(8.2 * cos 30 – 15)^2 + 0.6^2)]^0.5  

the magnitude is approximately 7.9 m  

tan θ = y/x = 0.6/-7.9  

the angle is approximately 4.3˚ north of west

the answer to 1/4x+5/3x-4=2-1/12x is x=3

hope this if needed hmu
