Mary = M Chris = C
M = 3C-4
M-3=C+9 --> M=C+12
3C-4=C+12
2C=16
C=8
M=3C-4 --> C=8
M=3(8)-4
M=24-4
M=20
Mary is 20, and Chris is 8
So that I don't want you have to do 18×12. Witch is L*W. which would be 216
Then the top you have to do base 1 Plus a base two and then times it by the height and that would be
10+18×6 which would be 118
Answer:
60.
Step-by-step explanation:
This is a permutation exercise because order matters. The formula is n!/(n-r)!. In this case n=5 and r=3 so,
5!/(5-3)! = 5!/2! = 5!/2 = (5*4*3*2*1)/2 we can simplify the 2 and obtain 5*4*3= 60.
Answer: 9/4
Step-by-step explanation:
The slope-intercept form is y = m x + b , where m is the slope and b is the y-intercept. y = m x + b Find the values of m and b using the form y = m x + b . m = 1/4 b = 2 The slope of the line is the value of m , and the y-intercept is the value of b . Slope: 1/4 y-intercept: 2 Any line can be graphed using two points. Select two x values, and plug them into the equation to find the corresponding y values. Choose 0 to substitute in for x to find the ordered pair. y = 2 Choose 1 to substitute in for x to find the ordered pair. Tap for fewer steps... Replace the variable x with 1 in the expression. f ( 1 ) = 1 4 + 2 Simplify the result. The y value at x = 1 is 9/4 . y = 9/4
Answer:
A (the first table)
Step-by-step explanation:
A is a function because none of the x-values are paired with more than one y-value
