Answer:
40%
Step-by-step explanation:
Total students = 25
Boys = 15
Girls = 25 - 15 = 10
Percent of girls = 10/25
Percent is out of 100.
=> 10/25 = x/100
=> Cross multiply
=> 25 * x = 100 * 10
=> 25x = 1000
=> 25x/25 = 1000/25
=> x = 40
So, 40% are girls
Solving the simultaneous equation show that the solution is inconsistent.
<h3>What is Inconsistent solution?</h3>
A simultaneous equation is said to have inconsistent solution when there is no value as the solution. This implies that no value of unknown will satisfy the equation.
Hence no value of x and y satisfies the equation.
4x -2y = 18 ______1
-4x + 2y = -18 ____2
from (1) make y the subject of formular
4x -2y = 18
2y = 4x - 18
y = 2x - 9 ______3
substitute y = 2x - 9 into 2
-4x + 2y = -18
-4x + 2 (2x - 9 ) = -18
-4x + 4x - 18 = -18
-4x + 4x = -18 + 18
0 = 0
This gives no solution hence the simultaneous equation is said to be inconsistent

Answer:
1. 62.5
2. 66.25
Step-by-step explanation:
25% of 50 is 12.5 add that to 50 is 62.5
6% of 62.5 is 3.75 so 3.75+62.5 is 66.25
Yearly salary would be 240,000 for 5,000 and 48,000 for 1,000 a week
Answer:
Step-by-step explanation:
Jackie you should know that the supplemental angles always add to 180° :)
That's like angles 1 & 2 or 55° & 1 . both are supplemental and add to 180°
Knowing this should make answering this pretty easy. :)
180 = ∠1 + 55
125 = ∠1
∠3 =∠1
∠2 = 55°
since line g is parallel to f , we know all the angles in the same places of line f are identical... got it?
