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.
<span>-2.9x + 5.4y = 140.94
answer is </span><span>y-intercept is 26.1
cause when </span><span>y-intercept x = 0
</span>-2.9(0)+ 5.4y = 140.94
<span>5.4 y = 140.94
y = 140.94 / 5.4
y = 26.1
