Question: When you do adding fractions, do you have to find a common demoniter? sorry for misspelling

1 answer:

5 0

Answer: yes when your adding or subtracting fractions you must find the common denominator between the two before you continue.

Step-by-step explanation:

Example: 2/4+3/2

Find the common denominator. ( in this case the common denominator is 4)

We keep the first fraction as it is cause it has the denominator 4 and we multiply the second fraction by 2 up and down to get a denominator of 4. The equation becomes 2/4+6/4

Now you add the numerators and you got your answer ( don’t forget to simplify)

The answer after adding in this case is 8/4 and when simplified it is 2

As the value of the multiple coefficient of determination increases,

Leona [35]

Answer:

a.the goodness of fit for the estimated multiple regression equation increases.

Step-by-step explanation:

As the value of the multiple coefficient of determination increases,

a. the goodness of fit for the estimated multiple regression equation increases.

As we know that the coefficient of determination measures the variability of response variable with the help of regressor. As we know that if the value of the coefficient of determination increases strength of fit also increases.

I am bored, answer with the BEST answer and I will make you brainliest............

Arada [10]

If it took you (one person) 3 days to build a doghouse, then it should take 2 people to build it in half the time. So all we have to do is split 3 days in 2.

3/2 = 1.5
So it would take 1 1/2 days or 36 hours for 2 people to complete the doghouse.

The diameter of a circle is 6 m. Find its area in terms of π π.

Xelga [282]

Step-by-step explanation:

this is totally simple.

the formula for the area of a circle (as you can find with any search on the internet in seconds) :

A = pi×r²

r is the radius.

and once you understand even the most basics of a circle, you know that the radius is half of the diameter.

so, in our case, r = 6/2 = 3 m

the area of the circle is therefore

pi×r² = pi×3² = pi×9 m²

2(4 - 2r) = -2(r + 5)

Alexus [3.1K]

2(4 - 2r) = -2(r + 5)

First, divide both sides by -2. / Your problem should look like: $-4 + 2r = r + 5$
Second, regroup your terms. / Your problem should look like: $2r - 4 = r + 5$
Third, add 4 to both sides. / Your problem should look like: $2r = r + 5 + 4$
Fourth, add r + 5 + 4 to get r + 9. / Your problem should look like: $2r = r + 9$
Fifth, subtract r from both sides. / Your problem should look like: $2r - r = 9$
Sixth, subtract 2r - r to get r. / Your problem should look like: $r = 9$

Answer: r = 9
