Understand the concept of a unit rate a/b associated with a ratio a:b with b ≠ 0, and use rate language in the context of a ratio relationship. For example, “This recipe has a ratio of 3 cups of flour to 4  cups of sugar, so there is 3/4 cup of flour for each cup of gallons of water.”How many cups of disinfectant are needed for 20 gallons of water so c is

I use ratio and proportion changes 3/4= .75 .75 cups/2 gallons= x cups/2o gallons cross multiply 2x= 15 x= 7 1/2 cups also there are 10 gallons for every 3/4 cup 10 x 3/4= 30/4= 7 1/2 I like ratio and proportion it's more consistent in solving lots of problems hope this helps

Using these complex zeros (1,1,-1/2,2+i,2-i) factor f(x)=-2x^5 +11x^4 -22x^3 +14x^2 +4x -5
Marianna [84]
\bf \begin{cases}&#10;x=1\implies &x-1=0\\&#10;x=1\implies &x-1=0\\&#10;x=-\frac{1}{2}\implies 2x=-1\implies &2x+1=0\\&#10;x=2+i\implies &x-2-i=0\\&#10;x=2-i\implies &x-2+i=0&#10;\end{cases}&#10;\\\\\\&#10;(x-1)(x-1)(2x+1)(x-2-i)(x-2+i)=\stackrel{original~polynomial}{0}&#10;\\\\\\&#10;(x-1)^2(2x+1)~\stackrel{\textit{difference of squares}}{[(x-2)-(i)][(x-2)+(i)]}

\bf (x^2-2x+1)(2x+1)~[(x-2)^2-(i)^2]&#10;\\\\\\&#10;(x^2-2x+1)(2x+1)~[(x^2-4x+4)-(-1)]&#10;\\\\\\&#10;(x^2-2x+1)(2x+1)~[(x^2-4x+4)+1]&#10;\\\\\\&#10;(x^2-2x+1)(2x+1)~[x^2-4x+5]&#10;\\\\\\&#10;(x^2-2x+1)(2x+1)(x^2-4x+5)

of course, you can always use  (x-1)(x-1)(2x+1)(x²-4x+5)  as well.

50+x(greater than or equal to)300
nikdorinn [45]

Answer:

x ≥ 250

Step-by-step explanation:

Note that "greater than or equal to" looks like ≥

50 + x ≥ 300

Isolate the variable. What you do to one side, you do to the other. Subtract 50 from both sides.

x + 50 (-50) ≥ 300 (-50)

x ≥ 300 - 50

x ≥ 250

x ≥ 250 is your answer.
