1. Expand
6x + a = 5x + 5t
2. Get x on one side
6x - 5x = 5t - a
3. Simplify
x = 5t - a (I think)
Answer:
The average weight of new born otter was, 
Step-by-step explanation:
Let average weight of new born otter be x.
As per the given statement: At birth it's weight was 7/8 kilograms which is 9/10 kilogram less than the average weight of a new born otter in the aquarium

Answer:
$9.90 per hour
Step-by-step explanation:
This month:
Initial pay: $10 per hour
% raise : 10%
Dollar amount of raise = 10% x $10
= 10/100 x 10 = $1
Gina's pay after the raise = $10 + $1 = $11 per hour
Next Month:
Starting pay: $11 per hour
% decrease : 10%
Dollar amount of decrease = 10% x $11
= 10/100 x 11 = $1.10
Gina's pay after decrease = $11 - 1.10 = $9.90 per hour
20+5=25 then 25-4.67=20.33 so then you do 20.33/4.5=4.5 so the cost for one pound of fruit is $4.57. Hope this helps :)
A. True. This is because distances are preserved and kept the same.
B. True. Moving any point to it's corresponding image is having you travel 8 units.
C. True. Corresponding angles are congruent.
D. False. This is not always true so in general it's false.
The final answer is choice D
