4(2x +5) = (8x + 20)
8x =20 is an equivalent expression
The answer is (5x - 4y)(2a + b)
10ax + 5bx - 8ay - 4by = 10ax + 5bx - (8ay + 4by) =<span>
= 5x * 2a + 5x * b - (2a * 4y + b * 4y) =
= 5x(2a + b) - 4y(2a + b) =
= (5x - 4y)(2a + b)</span>

Answer:
1 to 5
Step-by-step explanation:
20 cm to 1 m = 20 cm to 100 cm = 20 to 100 = 1 to 5
Given the marginal propensity to consume (MPC), the miltiplier is given by
Multiplier = 1 / (1 - MPC)
Given that the marginal propensity to consume is 0.8, the multiplier is given by
Multiplier = 1 / (1 - 0.8) = 1 / 0.2 = 5
Answer:
A) 2
Step-by-step explanation:
I<em>n a box-and-whisker plot, the left "whisker" is the bottom 25%, the line between the two "boxes" is to 50%, and the right "whisker" is the top 25%</em>.
In class 2, the 90 point mark is where the line between the boxes are, which means that 50% of the class earned 90% or less. That is 13/2 = <em>6.5 people</em> (this is impossible but it will work out)
In class 1, the 80 point mark is also where 50% is. So, half of the students, 17/2 = <em>8.5 people</em>, have 80 points or less.
<em>8.5 - 6.5 =</em> 2 people.
