The answer is 6 positive tiles.
Answer:
43 is not a composite number
Step-by-step explanation:
43 is a prime number
First you need to get x on one side of the equation and to do that subtract 2a from both sides.
28 + 2a = 5a + 7
-2a -2a
28=3a+7
Then we need to get a alone by subtracting 7 on both sides.
28=3a+7
-7 -7
21=3a
Finally divide each side by 3 and you should get a = 7. Hope this helps!
Answer:
I believe it's the last one.
Answer:
Please check the explanatio.
Step-by-step explanation:
Solving Part b)
We know that the slope-intercept form of the equation line is

where m is the slope and b is the y-intercept
Given the equation

Re-writing the equation in the slope-intercept form


Here, m=-2 and b=8
Thus, the equation in the slope-intercept form will be:

Solving Part c)
As you sold two pounds of cheddar cheese.
i.e. y=2
substituting y=2 in the slope-intercept form of the line equation


Subtract 8 from both sides


Divide both sides by -2


You sold 3 pounds of swiss cheese.
Solving Part d)

putting x=2.5 in the equation



The sides are not equal
<em>FALSE</em>
Thus, x=2.5 does not make any sense in the context of the problem.
