0.25 is one fourth of a foot. So there would be four 0.25 pieces per foot. Four times four yields 16 total pieces, each 1/4 foot in length.
The answer is B. (x-2,y+1)
Answer:
1.12
Step-by-step explanation:
1/4 of 5 =1.25
1.25-5= 3.75
3/10 of 3.75= 1.12
1. Simplifying
9x + 2y = 30
Solving
9x + 2y = 30
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-2y' to each side of the equation.
9x + 2y + -2y = 30 + -2y
Combine like terms: 2y + -2y = 0
9x + 0 = 30 + -2y
9x = 30 + -2y
Divide each side by '9'.
x = 3.333333333 + -0.2222222222y
Simplifying
x = 3.333333333 + -0.2222222222y

2. Simplifying
6x + 4y = 12
Solving
6x + 4y = 12
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-4y' to each side of the equation.
6x + 4y + -4y = 12 + -4y
Combine like terms: 4y + -4y = 0
6x + 0 = 12 + -4y
6x = 12 + -4y
Divide each side by '6'.
x = 2 + -0.6666666667y
Simplifying
x = 2 + -0.6666666667y
Answer:
We can call the angles 2x, 3x, and 4x. Since the sum of angles in a triangle is 180 degrees we can write:
2x + 3x + 4x = 180
9x = 180
x = 20 so the angles are 40°, 60°, and 80°.
