Answer:
The value of
:

Step-by-step explanation:
Find the value of
:

-Add both sides by
:


-Subtract both sides by
:


Divide both sides by
:


So, the final answer would be
.
The answer is 10 you see 6 people are in both of the classes so you have to subtract 6 from the 12 and 16 12+16-6=22
32-22=10
8 more red circles because if you have 9 red circles and 3 blue ones the ratio would be 9:3 and if you simplify that down to 3:1 that’s the answer. So you would need to add 8 more red circles
To determine how much of the barrel is left to fill, you must subtract the amount of water already in it from the total mass of the bucket.
25.5 - 5.2 = 20.3 Litres
In order to the fill the entire barrel, Kelly must collect 20.3 Litres of water. You must then covert the measurement from litres to millilitres so that the bucket and barrel are measured in the same units.
20.3L = 20300mL
You must then divide the amount of space left by the mass of the bucket. This will determine the least number of buckets needed to fill the barrel.
20300 <span>÷ 800 = 25.375
That means the you would have to do a minimum on 25.375 buckets to fill the barrel, or 26.
Hope this helps :) </span>
Answer:
This is true.
Step-by-step explanation:
Step 1: see that √27 is the same as √3*3*3 and thus 3√3
Step 2: remove parenthesis so that 2(1-3√3) becomes 2 - 6√3
Step 3: observe that the equation now becomes 6√3 + 2 - 6√3 = 2
if you simplify any further, you are left with 0=0, which is true.
