Answer:
There are 28 marbles in the box. Some are red (12), others are yellow (6) and others are blue (10).
If in this box there 28 marbles and 6 of them are yellow, we substract to get the quantity of marbles that aren't yellow: 28-6 = 22
So 22 of the 28 marbles aren't yellow: 22/28, which we can simplify dividing the numerator and denominator by 2: 11/14
Answer: x=1.6
y=4.2
Step-by-step explanation:
5.2x - y = 4.1
1.5x + y = 6.7
we will add both equations and you see that the y is getting cancelled
6.7x=10.8
x=10.8/6.7= 1.6
now in any equation we will replace x with 1.6
5.2(1.6)-y=4.1
8.3-y=4.1
-y= 4.1-8.3
-y=-4.2 multiply by -1
y=4.2
