Answer:
C
Step-by-step explanation:
3x + 3y = -x + 5y
3x + x = 5y - 3y
4x = 2y
Divide both by 2
2x = y
(1,2) when x=1, y=2
2(1)=2 is a true statement
(2,4) when x=2, y=4
2(2)=4 is a true statement
Answer:
D
Step-by-step explanation:
Because, the biologist wants to find the difference between the population of trouts from two watershed,
Answer:
Step-by-step explanation:
We have,
55 + 35
To find, the distributive property to factor out the greatest common factor,
55 + 35 = ?
We know that,
The distributive property of multiplycation,
The factors of 55 = 1, 5, 11 and 55 and
The factors of 35 = 1, 5, 7 and 35
The greatest common factor of 55 and 35 = 5
Using distributive property of multiplycation,
The greatest common factor = 5
Hence, the greatest common factor of 55 and 35 is .
Answer:
232 in^2
Step-by-step explanation:
Using the formula for surface area A=2(wl+hl+hw)
A=2(16+80+20)
A=232
Answer:
68 feet
Step-by-step explanation:
A submarine cruised below the surface of the water
During training exercise, each time descending= 45 feet
Number of dives= 4
Total distance he descended= 45×4 feet
Total distance he descended= 180 feet
Then, it rose by= 112 feet
Now , the distance he is at below the surface if water= 180- 112
The distance he is at below the surface if water= 68 feet
Now, he is at 68 feet below the surface of the Earth
Hence, the correct answer is 68 feet
