Answer:
19
Step-by-step explanation:
The opposite sides are equal, so:
PS = 3y+1
RS = 4y+2
QR = 3y+1
PQ = 4y+2
Therefore, we can set the perimeter 90 = PS+RS+QR+PQ
90 = (3y+1) + (4y+2) + (3y+1) + (4y+2), or,
90 = 2(3y+1) + 2(4y+2)
90 = 6y+2 + 8y+4
90 = 14y + 6
84 = 14y
y = 6
Then, we go back to the question. It's asking for the length of PS. PS = 3y+1, so we plug in 6 for y
3(6)+1
18 + 1 = <u>19</u>

Step-by-step explanation:
Answer:
-5
Step-by-step explanation:
Answer:
1) P(tacos)= 10/30= 1/3
2) P(Pizzas)=18/30 =3/5
3) P(T AND P)= 5/30= 1/6
4) P(T OR P)= P(T) +P(P) - P(T AND P)
= 10/30 +18/30 -5/30
= 23/30
