First do 18.6/3= 6.2
6.2+.29
6.49
100 = 2t + 4f
40= t + f
-----------
get t or f by itself first.
f = 40 - t : Then substitute it back into for f in the other equation
100 = 2t + 4f
100= 2t +4(40-t)
100= 2t + 160 - 4t
100 = -2t + 160
-160 -160
<u>-60 </u>= <u>-2t
</u>-2 -2
t = 30 (Then plug this into either equation to solve for f)
Therefore,
t = 30 questions
f = 10 questions
Equation: 3/4 + 1/6
3/4 = 18/24
1/6 = 4/24
18/24 + 4/24 = 22/24
22/24 = 11/12
Hope this helps!
You can make an equation for each situation where x is the number of bags and y is equal to the total number of oranges.
5x + 1 = y
4x + 3 = y
With substitution: 5x + 1 = 4x + 3
Solve for x.
5x - 2 = 4x
x - 2 = 0
x = 2
There is 2 bags, so plug that into either equation:
4x + 3 = y
y = 4*2 + 3
y = 11 oranges
