Answer:
x = 5
Step-by-step explanation:
Step 1: Subtract 2x from both sides.
4x−3−2x=2x+7−2x
<u>2x−3=7</u>
Step 2: Add 3 to both sides.
2x−3+3=7+3
<u>2x=10 </u>
Step 3: Divide both sides by 2.
2x/2 = 10/2
x=5
8o+12y=362
12o+8y=388
Im choosing “o” for orchid and “y” for lily
20o+20y=750
20o=750–20y
o=37.5–y
(37.5–y)+20y=750
-y+20y=712.5
19y=712.5
y=37.5
So, lilies sell for $37.50
Answer:
It should be red or green 125 times
Step-by-step explanation:
The first thing to do here is to calculate the probability of selecting a red or a green marble
Total number of marbles = 7 + 3 + 2 + 8 = 20
Probability of selecting a red marble is 7/20
Probability of selecting a green marble is 3/20
The probability of selecting a red or a green marble = Probability of selecting a red marble + Probability of selecting a green marble = 7/20 + 3/20 = 10/20 = 1/2
Now our selection spans 250 times, the number of times it should have been a green or a red marble = The probability of selecting a green or a red marble * number of selection times = 1/2 * 250 = 125 times
