Equation using the quadratic fromula for 0.05x^2 + 1.1x = 250

Anuta_ua [19.1K]

Answer:

x=60.56, x=-82.56

Step-by-step explanation:

Solve using quadratic formula

Formula is

$x=\frac{-b+-\sqrt{b^2-4ac}}{2a}$

0.05x^2 + 1.1x = 250

Subtract 250 on both sides

0.05x^2 + 1.1x - 250=0

a= 0.05, b=1.1 , c=-250

Plug in the values in the formula

$x=\frac{-1.1+-\sqrt{(1.1)^2-4(0.05)(-250)}}{2(0.05)}$

$x=\frac{-1.1+-7.156116265}{0.1}$

Now make two equations , one with + and one with -

then we solve for x

$x=\frac{-1.1+7.156116265}{0.1}$

x=60.56

$x=\frac{-1.1-7.156116265}{0.1}$

x=-82.56

Nari says, "The sum of 10 and one-third of a number is 25." She uses the bar model to write an equation to represent her

Mariana [72]

Answer:

$25=10+\frac{1}{3}n$ .

Step-by-step explanation:

It is given that the sum of 10 and one-third of a number is 25.

Let as consider n be the unknown number.

One-third of a number $=\frac{1}{3}n$

Sum of 10 and one-third of a number $=10+\frac{1}{3}n$

The sum of 10 and one-third of a number is 25. It can be written as

$25=10+\frac{1}{3}n$

Therefore, the required equation is $25=10+\frac{1}{3}n$ .
