Answer:
Therefore solution for a is
Step-by-step explanation:
Given:
7a - 2b = 5a + b
To Find:
a = ?
Solution:
7a - 2b = 5a + b .................Given
First take all the 'a' terms to the left hand side and 'b' terms to the right-hand side of the equation,
∴ 
Now dividing by 2 on both the side we get
∴ 
Therefore solution for a is

Answer:
a) 100000 feet
b) 1000000 feet
c) 10^5 and 10^6
Step-by-step explanation:
a) to find area, the formula is length x width
therefore, you would calculate 1000 x 100.
b) to find volume, the formula is length x width x height
therefore you would calculate, 1000 x 100 x 10.
c) look at the amount of zeros for each number and you will find your answer.
Hope this helps!!
Answer:
Beth is five years old.
Step-by-step:
Beth + Julio + Gerald + Debra = 38
B + (Beth - 2) + (2 x Beth) + (2 x Gerald) = 38
Since we know that Gerald is twice as old as Beth and Debra is twice as old as Gerald. That makes Debra four times older than Beth.
Beth + (Beth - 2) + (2 x Beth) + (4 x Beth) = 38
B + (B -2) + (2B) + (4B) = 38
Simplfy the like terms.
8B - 2 = 38
Add 2 on both sides.
8B = 38 + 2
8B = 40
Divide both sides by 8 to isolate the variable.
8/8 B = 40/8
B = 5
The answer is
-3 4/5 = -19/5
