Number 1 is Rio Grande and number 2 is St. Lawrence River
Step-by-step explanation:
If the original angle is x degrees then its supplement is 180 - x degrees.
we have the equation:-
180 - x = 3x + 20
160 = 4x
x = 40
The original angle is 40 degrees and its supplement is 140 degrees
Answer: x=3/2
Step-by-step explanation:
Multiply the parentheses by 2/3. 9=2/3x+8.
Multiply both sides by 3 . 27=2x+24
Move the term. When moved to the left side it changes from positive to a negative. -2x=24-27.
-2x=-3
Divide both sides by -2
x=3/2 (x=1 1/2, x=1.5)
Answer:
subtract the exponents:
a^7-2=a^5
Step-by-step explanation:
Answer:
C. 50
Step-by-step explanation:
Here we have to look at the given graph and find the answer.
The vertical axis represents the price and cost per unit. That is represented by P.
The horizontal axis represents the units of output, that is represented by q.
We need to find the number of units when p = $55.
By look at the graph of the curve MC, when P = $55, the number of units is 50.
Therefore, the answer is C. 50.
Hope this will helpful to understand the concept.
Thank you.
