So the answer is 14 ounces
Explanation
Since 16.8 is the original plus 20% we could say 16.8=120%

And since X is the original we could say X=100
So using that info we could put it into a proportion
120/100=16.8/x or
120. 16.8
——=. ———-
100. X
Then we cross multiply and divide
So,
120x=16.8(100)
120x=1680 then divide both sides by 120
X=14

PLS HELP ASAP NEED FOR A TEST
horrorfan [7]

Answer:

The answer in the procedure

Step-by-step explanation:

Let

x----> the first number

y----> the second number

we know that

\frac{x}{y}=\frac{3}{4}

so

y=\frac{4}{3}x -----> equation A

x+y=35 ----> equation B

substitute equation A in equation B

x+\frac{4}{3}x=35

\frac{3x+4x}{3}=35

\frac{7}{3}x=35    

x=35*3/7=15

y=35-15=20

F(x)=3x 2+x<br><br><br> Find f(−5)
Zina [86]

\huge \boxed{\mathfrak{Question} \downarrow}

  • f (x) = 3x² + x
  • Find f (-5).

\large \boxed{\mathfrak{Answer \: with \: Explanation} \downarrow}

Given,

  • f (x) = 3x² + x

Now, we have to find f (-5). To find this, we just need to substitute -5 in the place of x.

So,

\sf \: f(x) =  {3x}^{2}  + x \\  \\ \sf \: \: Substitute \: x \: as \:  - 5. \\  \\ \sf \:f( - 5) = 3( - 5) ^{2}  + ( - 5) \\ \\  \sf \:Calculate \:  -5 \:  to \:  the \:  power  \: of \:  2 \:  and \:  get \:  25. \\  \\\sf \: 3\times 25+5  \\  \\ \sf \:Multiply \:  3 \:  and \:  25 \:  to \:  get \:  75. \\ \\\sf \:  75+5  \\  \\\sf \:Add \:  75 \:  and \:  5  \: to  \: get  \: 80. \\   \\  =   \boxed{\boxed{ \bf \: 80}}
