Step-by-step explanation:
you need to substitute the x in (7x +2y=13) with (x=2y+11) to solve it
Look at the sides of the triangles. find the sides that are corresponding, or matching.
You would add the red marbles and green marbles together and which would be 7 the get the total marbles would be 9 so the answer would be 7/9 or 78%
Yes.
A fraction means that you divide the top number (numerator) by the bottom number (denominator). So, if you divide 4 by 16, then the answer is 0.25
Another way to get this answer is if you know your basic fraction-decimal conversions. If you reduce the fraction by dividing both the numerator and the denominator by the same number (in this case, 4 works), then you get the fraction 1/4, which is also equal to 0.25
Good luck with your math, and I hope this helps :)
