<h3>
Answer: 4x + 42 = 5</h3>
==========================================================
Explanation:
The fractions we want to eliminate are 2/3 and 5/6. The lowest common denominator (LCD) is 6.
If we multiply both sides by the LCD, then we'll cancel out the fractions. This is because
6*(2/3) = (6/1)*(2/3) = (6*2)/(1*3) = 12/3 = 4
6*(5/6) = (6/1)*(5/6) = (6*5)/(1*6) = 30/6 = 5
So in short, the (2/3)x becomes 4x and the 5/6 becomes 5 after we multiply both sides by the LCD 6.

This is what the steps could look like
Answer:
3x-4=26 |+4
3x=30 |:3 to get clear x
x=10
Hope this helps!!
Step-by-step explanation:
Let's turn this into a fraction using the given information we already have.
We want the denominator, or the bottom part of the fraction, to be 1 in order for us to have a unit rate.
This fraction can be simplified if we divide both the numerator and denominator by 3.
Numerator: 18/3 = 6
Denominator: 3/3 = 1
Now we have
Any number divided by 1 is equal to that number.
Thus, your unit rate is 6 miles per hour.
Have an awesome day! :)

Answer:
A) attached below
B) 0.61
C) 0.47
Step-by-step explanation:
Given data:
Total number of lizards infected = 38
Of the 15 species B lizards 40% survived
For specie C one more survived than died
Out of the 24 lizards that died 1/3 were species A
<u>A) contingency table </u>
attached below
<u>B) Determine the proportion of these lizards in this study that were either specie A or Specie B </u>
P ( A or B ) = ( 8 + 15 ) / 38 = 0.605 ≈ 0.61
<u>C) determine the probability that specie C lizard did not study </u>
P ( not surviving | C ) = 7 / 15 = 0.466 ≈ 0.47
