<h3>How to solve the simultaneous equation?</h3>
Given:
x-y=k.............(eq i)
2x²+y²-15..............(eq ii)
We would make y the subject formula in eq ii
2x²+y²-15= 0
2x² + y²= 15
y²= 15-2x²
y= ...........(eq iii)
Substitute the value of y into eq i
x-(= k
x- (= k
k=

D) 6 in
Step-by-step explanation:
The length is 24 feet. The blueprint scales 1 ft : ¹/₄ in.
So, we can set up a proportion: 1 ft / ¹/₄ in = 24 ft / x in
Cross-multiply: 24 * ¹/₄ = x
Multiply: x = 6 in(brainlist?
0
because a whole number means that there should be no fraction, decimal or negatives
1/8 = 0.125
since you have to round down
the answer would be 0
