Step-by-step explanation:
It is helpful to understand that the product of the binomial factors is ...
(ax +b)(cx +d) = ac·x² +(ad+bc)x +bd
For these problems you only need to look at the constant and the leading coefficient to find the missing values.
__
1. d = 8/-4 = -2
2. b = -24/(3·2·d) = -4; c = 3/(3·a) = 1
3. a = 2/c = 1; d = -24/b = 6
X+8=18 -8 -8
X=10 Value of x is 10
You just divide 26 by 60 and you get .4333 repeating. To make the decimal a percent you just move the decimal place two places to the right and get about 43%.
Answer:
Packages A and C
Step-by-step explanation:
To find the ratio between the number of lifts to the cost we first remove the $ symbol and find out how much 1 lift will cost per package.
Package A = 3 : 30
Package B = 5 : 60
Package C = 12 : 120
Package D = 16 : 120
Now let's break it down.
Package A = 30/3 = $10 per lift
Package B = 60/5 = $12 per lift
Package C = 120/12 = $10 per lift
Package D = 120/16 = 7.5 per lift
So now we are able to know which packages have the same ratio.
Package A and C cost $10 per lift.
