The blank space is found by dividing 36a^2 by 12, which is equal to 3a^2
To get to this answer you need to
1. divide the both sides of the equation by 12.
2. subtract 2b^2 from both sides.
You will see that the blank space equals 3a<span>^2 then</span>
Answer:
45, 180, 145
Step-by-step explanation:
Let n represent the first number. Then "one number" is 4n, and the third number is n+100. The sum of the three numbers is ...
n + 4n + (n+100) = 370
6n = 270
n = 45
4n = 180
n+100 = 145
The three numbers are 45, 180, 145.
Answer:
y = 30, x = 10
Step-by-step explanation:
y = 3x...eqn i
x = -2y + 70...eqn ii
Now,
Substituting eqn i in eqn ii,
x = -2y + 70
or, x = -2(3x) + 70
or, x = -6x + 70
or, x + 6x = 70
or, 7x = 70
so, x = 10
Now,
y = 3x = 3 * 10 = 30
For this case we have the following expressions:
Rewriting the second equation we have:
It is observed that by multiplying the first equation by 2, the second equation is obtained.
Thus, the equations are linearly dependent and since the lines are equal then they are intercepted in infinite points. Therefore, the system has endless solutions.
Answer:
Option D
