Sin F =9/18 = 1/2 = sin 30° (C)
Answer:
GCF is the largest factor that all terms have in common.
Answer: X=2
2x plus 2x plus 3x equals 7x and then you add the +5 which means you now have 7x+5=6x+7 which you then solve from there by subtracting the 6x from the left side. You then get x+5=7 meaning x=2.
x+3(x-5)=9 Substitute y=x-5 into every y into the first equation and solve for x
x+3x-15=9
4x=24
x=6
Substitute x into any equation and then solve for y.
y=(6)-5=1
x=6, y=1
Hope that helps!
2 x -6 equals 0. add 6 to both sides. divide both sides by two. x equals 3
