To solve this, you must first find out the value of n. Use algebra to get n by itself:
2n = 14
/2 /2
n = 7
Now, find out what 8n is by multiplying 8 and n.
8n
= 8(7)
= 56
So, 8n = 56
Hope that helps!
Answer:
cos0 = 6.8556546i/23 or sqrt-47/23
Step-by-step explanation:
hypotenuse is 23, opposite is 24
we have to find the adjacent using the pythagorean theorem
24^2 + b^2 = 23^2
576+b^2=529
subtract
b^2=-47
b=sqrt-47
sqrt of -47 is 6.8556546i, there is an i since it is the square root of a <em>negative</em>
cos = adjacent/hypotenuse
Answer:
c
Step-by-step explanation:
830$ there are 52 weeks in a year. 52 times 15 is 780. 780 plus 50 is 830
Answer:
z = 46/13
Step-by-step explanation:
Step 1: Write equation
z + 6 ÷ 13 = 4
Step 2: Solve for <em>z</em>
- Rewrite: z + 6/13 = 4
- Subtract 6/13 on both sides; z = 46/13
Step 3: Check
<em>Plug in z to verify it's a solution.</em>
46/13 + 6/13 = 4
52/13 = 4
4 = 4
