There is a common entity between the two terms of the given expression and that is the number 2 before each variable. We can factor out the 2 from the given expression and it becomes,
2 x (a + b)
Answer:
2 4/6 is what Haley has and 1 5/12 is what Michael has. I was unsure what the question was but I hope this answered it!
Step-by-step explanation:
The answer is 67
Add all the sides up and you get 67
Currently the equation 6x - 2y = 18 is in standard form. Convert the standard form equation into a slope-intercept form and we can find the slope easily.
Solve for y.
6x - 2y = 18
-2y = 18 - 6x <-- Subtract 6x from each side. This is to isolate the 2y term
2y / -2 =

<-- Divide each side by 2. This it to
get rid of the 2 coefficient.
y = -9 + 3x
Rearrange the right-hand side a bit.
y = -9 + 3x becomes y = 3x - 9
Now it is in slope-intercept form.
The slope is the coefficient of the x variable.
So, 3 is the slope.
90 ones would make 9 tens. It makes 9 tens because theres a 0 after 90. The 0 represents another place value. You can write this as 9 groups of ten
