Ahat [919]

Answer:

2 29/36

Step-by-step explanation:

So circle the two signs., so the problem is now this:

1/4+4/3+1 2/9

Then you find the GCM, or Greatest Common Denominator.

It is 36. Then, you re-write the new answers

9/36+ 48/36+ 1 18/36

Now we have this:

1 65/36

Which of the following equations represents a line that is parallel to the line 3x - 2y = 12
sveticcg [70]

Answer:

Step-by-step explanation:

12=3x-2y

2y+12=3x

2y=3x-12

y=(3x-12)/2

y=mx+b

To be parallel to the line above our line must have the same slope or m. The above line has a slope of 3/2 or 1.5 so the parallel line will be

y=1.5x+b, using point (7,10) we can solve for the y intercept or b

10=1.5(7)+b

10=10.5+b

b=-0.5 so our line is

y=1.5x-0.5

Evaluate the expression for f = -6 and g = -1.<br> fg - f =
Arlecino [84]

Answer:

7

Step-by-step explanation:

Given the information from the question:

fg - f = f \times g - f

Next we can use the order of operations to find the value of the expression.

fg - f =  - 6 \times  - 1 - ( - 1) \\  =  6 - ( - 1) \\  = 6 + 1 \\  = 7
