Solution for 3x-5=20 equation:
3x - 5 = 20
3x = 20 + 5
3x = 25 (divide both sides by 3 to get x)
3x/3 = 25/3
x = 8.33333333333

Answer:
6 items are being purchased
Step-by-step explanation:
Given that variable p represents the number of items being purchased, and the variable t represents the time required to ring up the customer, If it takes 44 seconds to ring up a customer then the number of items being purchased may be computed by substituting the value of t into the given equation
t = 4p + 20.
Using t = 44
44 = 4p + 20
collect like terms or subtract 20 from both sides
44 - 20 = 4p
24 = 4p
Divide both sides by 4
24/4 = p
p = 6
The slope can sometimes be called the gradient, and the equation for the gradient is (y2 - y1)/(x2 - x1). So therefore, you'd do: (-8 - 7)/(4 - -5) which is (-15)/9) which is -1 2/3 or -1.6 (recurring), which is your answer. I hope this helps! Let me know if I've confused you :)
Answer:
find the area of the triangle: 5*4=20 divided by 2 is 10.
split the second figure into a rectangle and triangle: 2*5=10 and 5*5 divided by 2 is 12.5
12.5+10+10=32.5
32.5
