Answer:

We can't graph on this app but this is what I can give you.

Step-by-step explanation:

The 5+2 part automatically makes 7, obviously, meaning that x and y each would have to at least represent 2 for this equation to be true.

What is the value of n in the equation 1/2(n – 4) – 3 = 3 – (2n + 3)?

Travka [436]

Distribute 1/2 to (n – 4):

 $\frac{1}{2} \times n = \frac{1}{2}n$
$\frac{1}{2} \times -4 = -2$

Subtract (2n + 3):

 $- (2n + 3) = -2n -3$

Your equation should now look like this:

 $\frac{1}{2}n - 2 - 3 = 3 - 2n - 3$

Combine like terms on both sides:

 $-2 - 3 = -5$
$3 - 3 = 0$
$\frac{1}{2}n - 5 = -2n$

Subtract 1/2n from both sides:

 $-5 = -\frac{5}{2}n$

Divide both sides by -5/2 to get n by itself:

 $n = 2$

The value of n is 2.

Jada has 7/8 cup of cheese. Her cheese bread recipe calls for 1/6 of chees. How many times can she make her recipe with the chee

Grace [21]

5 times because with common denominaters(remeber:what you do the top you always do to the bottom or what you do the bottom you do to the top)7/8=21/24 1/6=4/24.21 divided by 4 equals 5.5 but you want a whole loaf of cheese bread not a half so you would round it to 5.
