Answer:
110 apples
Step-by-step explanation:
Come up with an equation first. The equation I used is
0.5p - 5 = 50
I used p for pounds but it could be any letter
Now solve the equation, you want to get p by itself.
+5 +5
---------------------
0.5p = 55
Divide 0.5 from both sides
0.5/0.5 cancels out so now it looks like
p = 55/0.5
55/0.5 = 110
x = 110
And you can always check your work by plugging 110 into x and solving.
50 apples
50-5=45
25/.5=50
answers:
a. y = -6/5x + 4
b. y = 1/2x - 2
a.
5y = 20 - 6x
y = 20/5 - 6/5x
y = -6/5x + 4
b.
-8y = -4x + 16
y = -4/-8x + 16/-8
y = 1/2x -2
y=3|3+2|
Hope this helps!
