Step-by-step explanation:

Answer:
v > -25/p
r = -5 +7/3w
Step-by-step explanation:
-vp + 40 < 65
Subtract 40 from each side
-vp + 40 -40< 65-40
-vp < 25
Divide by -p. Remember to flip the inequality
-vp/-p > 25/-p
v > -25/p
7w - 3r =15
Subtract 7w from each side
7w -7w- 3r =15-7w
-3r = 15-7w
Divide by -3
-3r/-3 (15-7w)/-3
r = -5 +7/3w
The value of x is 21√2/2
The correct option is (A)
<h3>What is Trigonometry?</h3>
Trigonometry is a branch of mathematics that studies relationships between the sides and angles of triangles.
In triangle having angle 60.
sin 60 = P/ 7√3
√3/2= P/7√3
2P= 21
P= 21/2
Now again
cos 45= 21/2/x
1/√2 = 10.5/x
x= 21√2/2

Answer:
Sophia took a test with 21 questions.
If she answered two sevenths of the questions correctly, number of correct answers she did: N = 21 x 2/7 = 6
=> Number of answers she got wrong: N = 21 - 6 = 15
Hope this helps!
