Answer:
The answer to your question is 1.- (37/2, -9/2) 2.- g = 4 and h = 2
Step-by-step explanation:
Data
Equation 1 2x + 8y = 1
Equation 2 x = -3y + 5
Process
1.- Substitute equation 2 in equation 1
2(-3y + 5) + 8y = 1
Expand
-6y + 10 + 8y = 1
Solve for y
8y - 6y = 1 - 10
2y = -9
y = -9/2
2.- Substitute y in equation 2 to find x
x = -3(-9/2) + 5
Simplify
x = 27/2 + 5
x = 27/2 + 10/2
x = 37/2
Solution (37/2, -9/2)
2.-
Equation 1 6g + 8h = 40
Equation 2 -6g + 2h = -20
Process
1.- Add both equations
Result
0 + 10h = 20
Solve for h
h = 20/10
h = 2
2.- Substitute h in Equation 1 to find g
6g + 8(2) = 40
Simplification
6g + 16 = 40
Solve for g
6g = 40 - 16
6g = 24
g = 24/6
g = 4
Solution g = 4 and h = 2
Answer:
x=8
Step-by-step explanation:
Since angle 4x and 8x look like supplementary angles 4x+8x=180°. After solving that equation x=15. Plug that number in and 4x=60° and 8x=120°
2/3x+1=5-8
Combine like terms:
2/3x+1=-3
Subtract 1 from both sides
2/3x=-4
Multiply 3x from both sides
2=-12x
Now divide -12 from both sides
=-2/12
Simplify and you get -1/6 for your answer
The length in meters is 5.29 meters.
529 ÷ 100 = 5.29
