2.75 as a fraction or mixed number is 2 and 3/4. I know this because in order to change a decimal to a fraction, you must put the decimal over its place value, in this case 100. Then you keep the whole number. So you then have 2 and 75/100. 25 goes into both 75 and 100, making that what you would simplify by. 75÷25=3 and 100÷25=4. So you get 2 and 3/4.

It is known that x1 and x2 are roots of the equation x2−8x+k=0, where 3x1+4x2=29. Find k.
insens350 [35]

Answer:

The answer to your question is   k = -3233

Step-by-step explanation:

Data

x₁, x₂ are the roots

Equation l      x² - 8x + k = 0

Equation ll     3x₁ + 4x₂ = 29

k = ?

Process

1.- Write another equation

                     x₁ + x₂ = - 8

2.- Solve the system of equations by elimination

                      3x₁ + 4x₂ = 29          Equation l

                        x₁ +   x₂ = -8            Equation ll

-Multiply equation ll by -3

                      3x₁  + 4x₂ = 29

                    -3x₁   - 3x₂ = 24

                       0    + x₂ = 53

-Find x₁

                       x₁ + 53 = -8

                       x₁ = -8 - 53

                       x₁ = -61

2.- Find k

                      (x₁)(x₂) = k

                      (53)(-61) = k

                      k = -3233

116Mixed Practice #91.Write the area of the largest figure using two differentexpressions. All four-sided figures are rectangles
Scrat [10]

9)

We are given:

The largest rectangle has 3 rectangles:

Rectangle 1 has a length of x & a width of 5

Rectangle 2 has a length of 2y & a width of 5

Rectangle 3 has a length of 3 & a width of 5

The area is given by:

\begin{gathered} A=l\times w \\ A=x\cdot5+2y\cdot5+3\cdot5 \\ A=5x+10y+15 \\  \\ \therefore Area=5x+10y+15 \end{gathered}

OR

\begin{gathered} Area=length\times width \\ Area=5(x+2y+3) \\  \\ \therefore Area=5(x+2y+3) \end{gathered}
