The square root of 48 simplified is 4 sqrt 3.
4N + 3N = 35
7N=35
Divide both sides by 7
N = 5
In order to find out how long it is you need to convert the fractions into mixed fractions then multiply.
4 1/3 x 6 1/2 =
13/3 x 13/2 = 169/6
169 divided by 6 = 28 1/6
Answer:
and 
Step-by-step explanation:
First of all, even if the system is of 4th degree, by looking at the shape of the equations I am expecting up to 2 solutions.
The easiest way to solve it, since both equation are in the form y= something, is to equate both RHSs.
which tells us that either 
or 
Now we can replace these value of x in one of the two to finish our work: 
Answer:
(3, -2)

- Solving systems of equations using substitution/elimination
Step-by-step explanation:
<u>Step 1: Define Systems</u>
y = -x + 1
y = 4x - 14
<u>Step 2: Rewrite Systems</u>
y = 4x - 14
- Multiply everything by -1: -y = -4x + 14
<u>Step 3: Redefine Systems</u>
y = -x + 1
-y = -4x + 14
<u>Step 4: Solve for </u><em><u>x</u></em>
<em>Elimination</em>
- Combine equations: 0 = -5x + 15
- Isolate <em>x</em> term: -15 = -5x
- Isolate <em>x</em>: 3 = x
- Rewrite: x = 3
<u>Step 5: Check</u>
- Define equation: y = -x + 1
- Substitute in <em>x</em>: y = -3 + 1
- Add: y = -2
