Multiply the whole thing by (3a/3a) to get (6a)/(3+1)=6a/4=3a/2, so ya, 2nd is correct
Answer:
50.75m=5075cm=50,750mm
Step-by-step explanation:
50.75m=5075cm=50,750mm
Let's write out the problem with the triangles as "x" and the ovals as a number. Since there are 3 triangles and 5 boxes in the first box, the first box would be:
3x+5
In the other box, there are 11 ovals, so:
11
With this, they are equal, so:
3x+5=11
To solve this, move the 5 over onto the other side by subtracting 5 from each side:
3x+5<em>-5</em><em> </em>= 11<em>-5</em>
Then you have:
3x = 6
Now, divide doth sides by 3 to isolate x:
3x/3= 6/3
Now you're done!
<u><em>x=2</em></u>
Hope that helps.
Answer:
4/5 cup
Step-by-step explanation:
Hi.
First, what you would want to do is to find the total amount of the liquid before anything evaporated.
2/5 + 2/3
Find a common denominator
6/15 + 10 / 15 = 16/15
Now you know that 16/15 cups is how much broth there was before anything evaporated. Now you want to find out how much broth there was after 1/4 cup evaporated.
To find this, multiply 16/15 × 1/4
You will get 4/15
Lastly, you want to subtract the amount evaporated from the amount that was already there.
16/15 - 4/15 = 12/15 = 4/5 cup
