Y would be 28 because u need to add 17 to 11 to isolate y and the equation will be y=28
2 steps to this problem.
1) Figure out the length of the sides. The perimeter is:
2L + 2W
We know that the width is
of the length, so we can rewrite this to be
2L + 2(
)W
or in other words,
3.5L = 70
-->
L = 20
-->
W = 15
2. Figure out the length of the diagonal. The shape is a right triangle, so you can use the Pythagorean Theorem here.
-->
-->
= diagonal length = 25
21 green, 18 red, 23 blue, 23 yellow...total of 85
P(picking blue) = 23/85 = 0.27058..rounds to 0.2706
Answer:
23
Step-by-step explanation:
12+17+30+19+27+21+35=161
161÷7=23
