Answer:
31.96
Step-by-step explanation:
Answer:
The solution would be (-19, 40)
Step-by-step explanation:
In order to solve this system by substitution, simply take the value of y in the first equation and use it in place of y in the second. This will allow you to solve for x.
5x + 2y = 15
5x + 2(-3x - 2) = 15
5x - 6x - 4 = 15
-x - 4 = 15
-x = 19
x = -19
Now that we have the value of x, we can find the value of y.
y = -3x - 3
y = -3(-19) - 3
y = 43 - 3
y = 40
Answer:
33°
Step-by-step explanation:
11x = 1/2(x+63)
22x = x + 63
21x = 63
x = 3
IHJ = 11x
= 11(3) = 33°
Cos x = adj/hyp
Cos F = 6/10 = 3/5
Answer: 3/5
