You need to 8 + 4 = 12 and take the half of 12 and start at -4 and count up 6
Answer:
x = 437.3 ft
Step-by-step explanation:
Angle of elevation = angle of depression = 29°
Reference angle = 29°
Adjacent side = x
Hypotenuse = 500
Applying trigonometric ratio, we have:
Cos 29 = x/500
Multiply both sides by 500
500*cos 29 = x
437.309854 = x
x = 437.3 ft (nearest tenth)
Answer:
(2, 5 )
Step-by-step explanation:
Given the 2 equations
3x + 2y = 16 → (1)
2x + y = 9 → (2)
Multiplying (2) by - 2 and adding to (1) will eliminate the y- term
- 4x - 2y = - 18 → (3)
Add (1) and (3) term by term to eliminate y
- x = - 2 ( multiply both sides by - 1 )
x = 2
Substitute x = 2 into either of the 2 equations and solve for y
Substituting into (1)
3(2) + 2y = 16
6 + 2y = 16 ( subtract 6 from both sides )
2y = 10 ( divide both sides by 2 )_
y = 5
solution is (2, 5 )
How did they split the money
w = 12
to solve this, you have to multiply both sides by 2 to cancel out the two on the left. you’ll be left with -7w = 84. then, you divide both sides by -7 to isolate the variable, which is w. you’ll end up with w=12.
