Answer:

Step-by-step explanation:

multiplying fractions is usually super simple. You just multiply the top numbers and multiply the bottom numbers. So 2/3 * 5/7 = (2*5)/(3*7) = 10/21.

Here you have mixed fractions. For me, the easiest way is to make them improper fractions and then multiply them. So 2 and 3/4 becomes 11/4 and 1 and 13/20 becomes 33/20. Let me know if you don't get that.

Anyway, if we make the unknown fraction x we can rewrite this as an algebraic equation.

(11/4)x = 33/20 Now just multiply both sides by 4 and divide both sides by 11 and you will get

x = 3/5

Again, let me know if there's something you don't understand.

The equation of a line is y = –2x + 1. What is the equation of the line that is parallel to the first line and passes through (2

Phantasy [73]

Parallel lines have the same slope so for the new line we m=-2 and the point (2,2) we will substitute this info into our line to solce for b the y intercept.

Y=-2x+b
(2)=-2(2)+b
2=-4+b
2+4=-4+4+b
6=b

Now we put it all together using the slope m=-2 and the y intercept of 6
Y=-2x+6
