Answer:
$4.25
Step-by-step explanation:
.75 x 3 +2 +4.25
Answer:
x = 360
Step-by-step explanation:
Reorder the terms:
x = 72 + 0.8x
Solving
x = 72 + 0.8x
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-0.8x' to each side of the equation.
x + -0.8x = 72 + 0.8x + -0.8x
Combine like terms: x + -0.8x = 0.2x
0.2x = 72 + 0.8x + -0.8x
Combine like terms: 0.8x + -0.8x = 0.0
0.2x = 72 + 0.0
0.2x = 72
Divide each side by '0.2'.
x = 360
Simplifying
x = 360
Answer:
a) 3/2 or 1.5
b) 2/3 or ≈.66
Step-by-step explanation:
AB corresponds to DE because they are both the longest sides of their respective triangles.
a) The scale factor would be what you would multiply 8 by to get 12. 12/8 is 3/2 or 1.5
b) The scale factor would be what you multiply 12 by to get 8. 8/12 is 2/3 or ≈.66
Answer:
2y=11 - 5x
Step-by-step explanation:
An equation that is parallel shares the same gradient thus
2y= -5x - 8
y = -5/2x- 4
gradient m = -5/2
substitute value of m and the co-ordinates into a new linear equation
y = mx + c
-9 = (-5/2)(8) + c
c = 20-9 = 11
thus y = -5/2x + 11
2y=11 - 5x
multiplication is for example 10×500=5,000
division is for example 5,000÷10=500
