8+4= 12, 12 times 7 is equal to 84.
Answer: Answer below.
Step-by-step explanation: If x is pi, and y is 1/pi, then multiplying x by y is 1; yes. So, for y, 1 is being divided by pi. The opposite of division is multiplication. If you multiply 1/pi by pi, the pi in the denominator cancels. Just how if it is 5x = 10, dividing by 5 cancels it on the left side, and gets you x = 2.
This is general for everything. If you multiply 2 by 1/2, you get 1. This is because dividing is also like multiplying by its reciprocal. 1/2's reciprocal is 2/1, and multiplying leaves you with 1. Go and use a calculator, it's correct. Actually, any problem a/b × b/a = 1.
Answer:
y1= 0, y2= 5/3
Step-by-step explanation:
Remove the parentheses and multiply
then cancel the equal terms
collect the lie terms
move the variables to one side
divide both sides by two
split into possible cases
then solve the equation to get
y= 0 and
y= 5/3
Answer:
Step-by-step explanation:
There are total 300 pieces of candy.
Adrian gets 1/4 of total
<u>Multiply the total number by 1/4, to find the number Adrian gets:</u>
Darien gets 10% of total.
<u>10% is equal to 10/100 = 1/10. Multiply 300 by 1/10 to get the number Darien gets:</u>
The little brother gets 25 pieces.
<u>Number of pieces Jordan has given:</u>
<u>Number of pieces left:</u>
