4y=-21+5
4y=-16
y=4
simplified
Divide both sides with 9
s = 16
Answer:
Solve for x by simplifying both sides of the equation, then isolating the variable.x≈−0.00413995,1.6090059
Step-by-step explanation:
Answer:
1. x=55 2. x=12
Step-by-step explanation:
1. 3x-60=x+50
2x=110
x=55
2. 8x-34=5x+2
3x=36
x=12
Answer:
x = 3.25 m
Step-by-step explanation:
First, find the height of the triangle using sin31:
sin 31 = h/9 ---> h = 9sin31 = 4.64 m
Next, we can now solve for x using tan55:
tan 55 = h/x --> x = (4.64 m)/(tan 55) = 3.25 m
