Answer:
d = 10
Step-by-step explanation:
50 + 2 ( 2 - d ) = 3 ( 1 + d ) + 1
50 + 4 - 2d = 3 + 3d + 1
54 - 2d = 4 + 3d
- 4 -4
50 - 2d = 3d
+2d +2d
50 = 5d
50/5
d = 10
Answer:
d=65
Step-by-step explanation:
Simplifying
4x + 16 + -1x = 22 + 6
Reorder the terms:
16 + 4x + -1x = 22 + 6
Combine like terms: 4x + -1x = 3x
16 + 3x = 22 + 6
Combine like terms: 22 + 6 = 28
16 + 3x = 28
Solving
16 + 3x = 28
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-16' to each side of the equation.
16 + -16 + 3x = 28 + -16
Combine like terms: 16 + -16 = 0
0 + 3x = 28 + -16
3x = 28 + -16
Combine like terms: 28 + -16 = 12
3x = 12
Divide each side by '3'.
x = 4
Simplifying
x = 4
Rain : sunny : overcast
7:11:3
7x + 11x + 3x = 366
21x = 366
x = 366/21
x = 17.43
7(17.43) = 122.01 days rain
11(17.43) = 191.73 days sunny
3(17.43) = 52.29 days overcast
Step-by-step explanation:
Given points (-1 , -2) and (3 ,10)
First calculating slope
Slope(m) = (y2 -y1) / (x2 - x1)
= ( 10+ 2)/ ( 3 + 1)
= 12 / 4
= 3
Now The equation of line is
y - y1 = m ( x - x1)
y +2 = 3 ( x +1)
y+2 = 3x + 3
y = 3x + 3 -2
y = 3x + 1
