Answer:5
Step-by-step explanation:
6:30 is the ration
6/30 reduced is 1/5
1:5
so its 5
<em /><em>PURPLE MARBLES=P
WHITE MARBLES=W
</em>First, write out an equation showing the number of purple marbles.
P=5W-6
Then, write out the main equation.
W+P=96
W+5W-6=96
Add 6 to both sides.
W+5W=102
6W=102
Divide both sides by 6
W=17
Now that we know there are 17 white marbles, we can go back to the equation about how many purple marbles there are.
P=5W-6
Plug in the value for W, which is 17.
P=5(17)-6
P=85-6
P=79
To make sure your answer is correct, check your work by plugging in the values for P+W=96.
79+17=96
Answer: There are 79 purple marbles.
You would minus 12 on both sides which would give you d= -16.8 meters it’s a negative answer btw
Hope this helps
Answer:
w> 6
Step-by-step explanation:
Let w= the width
Let 4w = length
So then your equation becomes
2(w) + 2(4w) >60
Distribute
2w+8w > 60
Combine like terms
10w > 60
Divide by 10
w > 6
