Answer:
4 minutes
Step-by-step explanation:
Let the time taken for them to have the same number of strawberries be x minutes.
<u>Initially</u>
Ruby: 10 strawberries
Sapphire: 30 strawberries
<u>After x minutes</u>
Ruby: (10 +3x) strawberries
Sapphire: (30 -2x) strawberries
Since we let x minutes be the amount of time that has passed when they have the same amount of strawberries,
10 +3x= 30 -2x
Bring all x terms to one side, constant to the other:
3x +2x= 30 -10
Simplify:
5x= 20
Divide both sides by 5:
x= 20 ÷5
x= 4
∴ It will take 4 minutes.
Answer:
(attached file #2)
Step-by-step explanation:
let's change the variable n to a variable x (it can be x and y):
x ≥ -8
go to the X-axis which is the line going horizontal, just as the first picture attached!
2. Now go to the -8 on that line and draw a straight bold line going up (vertical)
and there you have the answer to the question.
if the question was with this symbol: < or > then the line would be dashed instead of being a bold solid straight line!
Hope this helps,

ok so 1 inch=30 yards so 4 inch=?
1/30=4/x
1x=30(4)
x=120
so the actual distance is 120 yards
The answer and work is shown by the picture given.
