Mathematics

Blababa [14]3 years ago
7 0

Answer:

  -2.1x +14.4y

Step-by-step explanation:

Use the distributive property to eliminate parentheses. Then combine like terms.

  (12.7y-3.1x)+5.9y-(4.2y-x)

  = 12.7y -3.1x +5.9y -4.2y +x

  = x(-3.1 +1) +y(12.7 +5.9 -4.2)

  = -2.1x +14.4y

(-10x)(2) is there any chance you can help please and thanks
Svetllana [295]
The answer is -20x, because the parentheses show they are being multiplied, so you multiply -10x and 2, which would be -20x.

How to write 2.31818 as a mixed fraction
Elenna [48]

Answer:

2\frac{15909}{5000}

Step-by-step explanation:

To make 2.31818 into a fraction, you must first move it to the numerator and make 1 the denominator.

\frac{2.31818}{1}

And then you multiply it by 10,000 or you can say 10^5

\frac{2.31818}{1}*\frac{100000}{100000}

After you multiply you divide the numerator and denominator by 2.

\frac{231818/2}{100000/2}

And now this equals:

2\frac{15909}{5000}

Hope this helps!
