Answer:
27
Step-by-step explanation:
First, we need to find x. We are given the perimeter, which is 2l + 2w, so from there, we have an equation of 2(4x-1) + 2(3x+2) = 100. By working through it, we get that x = 7. We're asked to find WX, so plug 7 into 4x - 1 and get 27.
Answer:
33
Step-by-step explanation:
I believe that the question is asking this
4q+25 and not 4(q+25)
so 4(2)=8+25 is 33
So 4 times a number q means 4*q and when q is 2 you will get 8 and when you add that to 25 you get 33
P(orange and then a purple) is 15/56.
P(two purples in a row) is 6/56.
<u>Step-by-step explanation:</u>
- A bag contains 3 purple and 5 orange jelly-beans.
- The total jelly-beans in the bag = 3 purple + 5 orange = 8 jelly-beans.
<u>Without replacement, find P(orange and then a purple) :</u>
P (orange) = No.of orange jelly-beans / total jelly-beans.
⇒ 5 / 8
P (purple) = No.of purple jelly-beans / remaining jelly-beans from the total
⇒ 3 / 7
P(orange and then a purple) = P (orange) × P (purple)
⇒ 5/8 × 3/7
⇒ 15/56
<u>Without replacement, find P(two purples in a row) :</u>
P (1st purple) = No.of purple jelly-beans / total jelly-beans.
⇒ 3 / 8
P (2nd purple) = remaining no.of purple jelly-beans / remaining jelly-beans from the total.
⇒ 2 / 7
P(two purples in a row) = P (1st purple) × P (2nd purple)
⇒ 3/8 × 2/7
⇒ 6/56
20 ÷ (5 × 2 - 6) + 8=20:(10-6)+8=20:4+6=5+6=11
(20 ÷ 5) × 2 – 6 + 8=4*2-6+8=8-6+8=2+8=10
20 ÷ (5 × 2) – 6 + 8=20:10-6+8=2-6+8=-4+8=4
(20 ÷ 5) × (2 – 6) + 8=4*(-4)+8=-16+8=-8
