kati45 [8]
Say there are two fractions, 1/3 and 3/7. first, find a common denominator (21). Multiply each number like this: 1/3 * 7/7= 7/21 and 3/7 * 3/3=9/21. Now, just compare. 7/21 is less than 9/21. :)

What is the solution of <br> y = 3x – 4 –3y = –9x + 12
AlexFokin [52]

9514 1404 393

Answer:

  any solution of y = 3x -4

Step-by-step explanation:

The two equations describe the same line. There are an infinite number of solutions. Any values of x and y that satisfy either equation will satisfy both equations.

1) A microbiologist measures the length of a bacterium of 0.000163 m and the
sashaice [31]

Answer:

a) The bacterium is longer;

b) The bacterium is 0.1543 mm longer than the yeast.

Step-by-step explanation:

In order to compare the length of the two beings we need to convert them to the same unit. We can do it either way, but we'll choose to convert from meters to milimetres, since we're dealing with small numbers. To do that we need to multiply the length that is in "m" by 1000.

length_{bac} = 0.000163*1000 = 0.163 \text{ mm}

a) The bacteria is longer than the yeast.

b) We need to subtract their length in order to find this answer:

\text{dif} = length_{bac} - length_{yeast}\\\text{dif} = 0.163 - 0.0087 = 0.1543 \text{ mm}

Answer:

m = \frac{-y+x}{2}

Step-by-step explanation:

2m - x + 3y = 2y

Take -x and +3y on the other side of the equal to sign:

2m = 2y +x-3y

Now solve for y:

2m = -y +x

Take 2 one the other side of the equation:

m = \frac{-y +x}{2}

Hope this helps :)
