Answer:
the mean of the data is 13, so the result is given by the sum of all data (11+12+13+14+15) and divided by 5
200 because 25 x 8 = 200 because perimeter is the outside it =)
Well, 1 is in the tenths place, which means it's equal to 1 tenth, or 1/10.
Answer:
The two numbers are - 12 and - 12 .
Step-by-step explanation:
Let the two numbers be x and y then
By the question
x * y = 144
or x = 144 / y ....... I)
Again
x + y = - 24
Or 144/y + y = - 24
or, ( 144 + y²) / y = - 24
or, 144 + y² = - 24y
y² + 24y + 144 = 0
y² + ( 12 + 12 ) y + 144 =0
y² + 12y + 12y + 144 = 0
y(y + 12 ) + 12 ( y + 14) = 0
( y + 12 ) ( y + 12 ) = 0
Either
y + 12 =0
y = - 12
Now
x = 144 / - 12 = - 12
Therefore the two numbers are - 12 and - 12 .
Hope it will help :)❤
16 - 12x = 4y
First, divide both sides by 4. / Your problem should look like: \frac{16-12x}{4} = y
Second, factor out the common term 4. / Your problem should look like: \frac{4(4-3x)}{4} = y
Third, cancel 4. / Your problem should look like: 4 - 3x = y
Fourth, switch sides. / Your problem should look like: y = 4 - 3x
Answer: y = 4 - 3x
