If alonzo is x then the equation is
x + (x +3) + 2(x + 3) = 57
Which equals
x + x + 3 + 2x + 6 = 57
4x + 9 = 57
4x = 48
x = 12
This means alonzo is 12 years old and alexis is 3 years older so alexis is 15 years old
Answer = 15 years old
Simple, it is equal to |4|, you have to draw the lines around the 4 on the worksheet.
For this case you can write a weighted average expression to find the average number of tickets sold per child.
We have then that an expression that can represent this average is the following:
average = (((tickets1) * (class1)) + ((tickets2) * (class2)) + ((tickets3) * (class3))) / ((class1) + (class2) + (class3))
answer
an expression for the average number of tickets sold per school child is
average = (((tickets1) * (class1)) + ((tickets2) * (class2)) + ((tickets3) * (class3))) / ((class1) + (class2) + (class3))
Answer:
y = -2x + 3
Step-by-step explanation:
y = mx + b
slope = m
m = y2 - y1/x2 - x1
-3 - 3/3 - 0 = -6/3
m = -2
y = -2x + b
b = y-intercept
b = 3
y = -2x + 3
