X is 26
Just divide 196 by 7
Answer:
3 years
Step-by-step explanation:
A=P( 1+rt)
A= Total amount
P= Principal
r = yearly interest
t= time in year
672=600(1+0.04t). Distribute
672=600+600x0.04t
72= 24t
t= 3 years
Answer:
D) $8.20
Step-by-step explanation:
82 x 0.1 = 8.2
Answer:
Step-by-step explanation:
We have been given an equation 
. We are asked to solve our given equation.
First of all, we will add 
on both sides of equation to separate x variable on one side of equation.
Now, we will make a common denominator.
Add numerators:
Upon multiply both sides of our equation by 
, we will get:
Therefore, the solution for our given equation is .
Trig ratios can only be used on right triangles with acute measures.
If given an angle and there are adjacent and opposite sides, then use tan(opposite/adjacent)
If given an angle and there is an adjacent side and a hypotenuse, then use cosine(adjacent/hypotenuse)
If given an angle and there is an opposite and adjacent side, then use sin(opposite/hypotenuse)
A common mnemonic device used to memorize the trig rules is SOH-CAH-TOA
