Yo sup??
we can apply trigonometric ratios here
cos45=BC/n
BC=n*cos45
=n*1/√2
=n/√2
=n√2/2
Therefore the correct answer is option D
Hope this helps
Answer:
20000000000000000000000000000
Im not exactly sure but wouldnt it be 24:1 for the ration?
<em><u>Question:</u></em>
Which of the following is another way to express the equation 8 - (-d) = 43?
A.8-d=43
B.-d+8=43
C.-8+d=43
D.8+d=43
<em><u>Answer:</u></em>
8 + d = 43 is another way to express the given equation
<em><u>Solution:</u></em>
Consider the given equation
We have to find the another way to express the above equation
We know that,
We we multiply negative sign number by another negative sign number, then the result is positive sign number
Therefore from given,
<em><u>Thus the given equation becomes,</u></em>
8 + d = 43
Thus option D is correct
5x-3y=16
3x-5y=-4
Multiply the first equation by 3; the second one by 5
15x-9y=48
15x-25y=-20
Eq 1 - Eq 2:
-9y+25y=48+20=68
16y=68
4y=17
y=17/4
5x-3y=16
5x-3×17/4=16
5x=16+51/4=(64+51)/4=115/4
x=115/4/5=23/4
x=23/4
