Simplify x - 3/3 to -1 + x/3
regroup terms
multiply both sides by 6 (The LCM of 2,3)
expand
subtract 2x from both sides
simplify 3x + 12 - 2x to x + 12
subtract 12 from both sides
simplify -6 - 12 to -18
Answer: x = -18.
A, since y is the change he will get, it will obviously be less than 100.
We are given
Andre rode his bike at a constant speed he rode 1 mile in 5 minutes
Firstly, we will find constant speed
In 5 minutes , distance travelled =1 miles
so, we get speed
Let's assume T is time in minutes
D is the distance in miles
we know that
so, we can plug value
and we get
so, we get

You would use the simple format SOH-CAH-TOA
SOH: sine = opposite/hypotenuse
CAH: cosine = adjacent/hypotenuse
TOA: tangent = opposite/adjacent
----
So for this problem to find c you would use this equation:
sin42= c/7
7sin42=c
c=4.68
Then for d you would use this equation:
tan48=d/4.68
4.68tan48=d
=5.197
Hope this helps :)
