A mug is 3/7 full. The mug contains 4/7 of a cup of water. Find the capacity of the mug.
Ira Lisetskai [31]

Answer:

7/6 cups

Step-by-step explanation:

Mug is 2/7 full

Amount of water in the mug = 1/3 cup

Assume the full capacity of the mug = m

Then the current capacity of water in mug = (2/7) of m = (2/7)m

Current capacity of water in mug is equivalent to 1/3 cup of water

Hence,

(2/7)m = 1/3

2m/7 = 1/3

Cross multiply

(2m * 3) = 7 * 1

6m = 7

m = 7/6

m = 1 1/6 cups

0.6( 10n + 25 ) = 10 + 5n
Doss [256]

Answer:

n=−5

Step-by-step explanation:

0.6(10n+25)=10+5n

Step 1: Simplify both sides of the equation.

0.6(10n+25)=10+5n

(0.6)(10n)+(0.6)(25)=10+5n(Distribute)

6n+15=10+5n

6n+15=5n+10

Step 2: Subtract 5n from both sides.

6n+15−5n=5n+10−5n

n+15=10

Step 3: Subtract 15 from both sides.

n+15−15=10−15

n=−5

If b = 3, then 3x + y = 1 and bx - y = 3 are parallel.<br> True or <br> False ...?
Ulleksa [173]
I am absolutely sure that the task <span> b = 3, then 3x + y = 1 and bx - y = 3 is NOT parallel, which means that the statement represented above is FALSE.
To make sure you can check it using : </span>y=-3x+1&#10;&#10;y=3x-3 Hope now it's obvious. Regards!
