Answer:
A
Step-by-step explanation:
1x + 2y = 4 ⇒ 3x + 6y = 12
3x + 2y = 0 ⇒ <u>3x + 2y = 0</u>
<u>4y</u> = <u>12</u>
4 4
y = 3
x + 2y = 4
x + 2(3) = 4
x + 6 = 4
<u> - 6 - 6</u>
x = -2
(x, y) = (-2, 2)
p = q + 2
3p + 2q = 9
3(q + 2) + 2q = -9
3(q) + 3(2) + 2q = -9
3q + 6 + 2q = -9
3q + 2q + 6 = -9
5q + 6 = -9
<u> - 6 - 6</u>
<u>5q</u> = <u>-15</u>
5 5
q = -3
p = q + 2
p = -3 + 2
p = -1
(p, q) = (-3, -1)
Answer:
The value of x is 12.5.
Step-by-step explanation:
We are given with the following proportion below;
To find the value of 
, first we have to find the number by which 12 must be divided so that we get 5 as a result.
That number is 2.4, that is if we divide 12 with 2.4 we get the result as 5.
So, 
This means that 
.
So, we get the value of x = 12.5.
Now, to check the solution to this proportion, we use cross multiplication method;
150 = 150
Since both sides of the equation are equal, that means our value of x = 12.5 is correct.
