3000g = 3kg
150g + 500g + 3000g = 3650g
3650g divided by 5 = 730g

She should put 730g into each bag.

(3kg(1000g/kg)+150+500)/5=730g/bag

Solve the system of equations algebraically show all work. <br><br> Y=-x^2+8x+11<br><br> Y=5x-7
morpeh [17]

Answer:

ummmm..... let's see..

Step-by-step explanation:

using "Almighty formula"

{Y = –x +/– √b^2 – 4ac / 2a}

so we name all the values behind the coefficients which are; –1^2, 8 and 11

so let's assign a,b,c to these values:

a =–1, b =8, c = 11

all you just do now is to add these values to the formula

you should be having Y =1 +/– √8^2 – 4×–1×11

———————————

2×–1

Y =1 +108

———— or Y = 1–108

–2 –––––

–2

now add and divide to get Y.

(your answer will be two)

Farmer Bill sold potatoes at the farm market. He sold a quarter to the first person, 4/9 of what was left to the second person,
mel-nik [20]

Answer: 120 lb of potatoes.

Step-by-step explanation:

Let the pounds of potatoes sold by farmer Bill      = X lb

Fractional part sold to the first person                    = 1/4

Therefore 1/4 of X                                                      = 1/4  x X

                                                                                    = X/4 lb of potatoes.

No of potatoes left for sale                                        = X - X/4

                                                                                    = ( 4x - x )/4

                                                                                    = 3x/4 lb.

Fractional part sold to the second person out of the reminder = 4/9

Therefore 4/9 of 3x/4                                                 = 4/9 x 3x/4

                                                                                    = x/3 lb of potatoes.

Amount of potatoes left for sale                               = 3x/4 - x/3

Resolve into fraction , we have                                 = (9x - 4x)/12, because 12 is the LCM.

                                                                                    = 5x/12

Third buyer bought 4/5 of the left over                    = 4/5 of 5x/12

                                                                                   =   x/3 lb of potatoes.

Amount  of potatoes left                                           =   5x/12 - x/3

Resolve in to fraction again  taking 12 as the LCM =   ( 5x - 4x )/12

                                                                                   = x/12 lb of potatoes .

Therefore, the left over was 10 lb .

To determine the value of x now which correspond to the amount of potatoes sold by Farmer Bill, we shall the equate the left to  x/12 = 10                                                                                                                

we now cross multiply to get the value of x                             x = 120 lb.

therefore the pound of potatoes sold by farmer Bill  = 120 lb.

Help me do 1/6+1/4 make sure the demonator is the same
Alik [6]
<h2><u>Answer: </u></h2><h2> \boxed{\boxed{\sf\frac{5}{12}=0.416666667}}</h2><h2></h2><h2><u>Solution Steps: </u></h2>

______________________________

<h3>1.) Find the LCF of 6 and 4: </h3>
  • 6,4=12

<em>  - We do this because in order to add these, they must have the same denominator. So you must find the LCF, (Least Common Factor) of 6 and 4.</em>

<em />

<h3>2.) Convert the fractions to have the same denominator: </h3>
  • \frac{1}{6}=\frac{2}{12}
  • \frac{1}{4}=\frac{3}{12}

<em>  - </em>\frac{1}{6}<em> changes to </em>\frac{2}{12}<em> by multiplying the numerator and denominator by 2. And  </em>\frac{1}{4}<em> changes to </em>\frac{3}{12}<em> because you multiply the numerator and denominator by 3. </em>

<em></em>

<h3>3.) Add the numerators: </h3>
  • 2+3=5

<em>  - Since both fractions have the same denominator all you have to do is add the numerators together. </em>

<em />

1.Could each value be an input ofthe function? Be prepared to explain your reasoning. 15 84/1/2 300
denpristay [2]

Answer:

Step-by-step explanation:

A function is a specific type of relation in which each input value has one and only one output value. An input is the independent value, and the output value is the dependent value, as it depends on the value of the input.
