You remember from SOH CAH TOA that
.. Cos = Adjacent/Hypotenuse
.. cos(C) = 80/82 = 40/41 . . . . . . . . . . . seems to match the last selection
Make each adult x and each kid 5x
and
set equal to 14.
so it would be
3.5x=14.
14/3.5 = 4
so
x = 4.
adult tickets are 4$ while kids are 2$
17 + x = 26
17 +n = 26
n + 17 = 26
something like those, you didn't give options to choose from.
Step 1: Simplify both sides of the equation.
3(x−5)−5=23
(3)(x)+(3)(−5)+−5=23(Distribute)
3x+−15+−5=23
(3x)+(−15+−5)=23(Combine Like Terms)
3x+−20=23
3x−20=23
Step 2: Add 20 to both sides.
3x−20+20=23+20
3x=43
Step 3: Divide both sides by 3.
3x
/3 = 43

x=
