Since you already have y isolated on one equation it's easy. Plug in 3x-11 as for for the second equation. Solve and find what x equals. Then plug the x into the first equation to find y. Hope this helps!
Answer:
There's a 37.5 percent chance that a boy will be selected.
Step-by-step explanation:
15/40=?/100
100 times 15 is 1500
1500 divided by 40 is 37.5
Perimeter is equal to 2l+2w, or 2 times the length plus 2 times the width.
So to solve for this you'd take 2(6.5) + 2(4.23).
2(6.5)= 13
2(4.23)= 8.46
13+8.46= 21.46 meters.
Based on this, the answer is C.
If you show the following than it can be answered, but 39/5 converted would be 7 4/5
