Answer:

$x = \boxed{2}\: and\: x = \boxed{ \frac{5}{2} }$

Step-by-step explanation:

$2 {x}^{2} - 9x + 10 = 0 \\ \\ 2 {x}^{2} - 4x - 5x + 10 = 0 \\ \\ 2x(x - 2) - 5(x - 2) = 0 \\ \\ (x - 2)(2x - 5) = 0 \\ \\ x - 2 = 0 \: \: 2x - 5 = 0 \\ \\ x = \boxed{2} \: and \: x = \boxed{ \frac{5}{2} } \\ \\$

Evaluate the expression and enter your answer in the box below |98|

Hi student, let me help you out! :)

. . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .

We are asked to evaluate $\pmb{|98|}$ .

$\triangle~\fbox{\bf{KEY:}}$

The notation |x| denotes absolute value.

The absolute value of a number is its distance from zero.

Absolute value is always positive; distances can't be negative, right?

So we need to find the absolute value of 98, which is:

$\star~\star\mathrm{98}~\star~\star$

$\ddot\bigstar$ Remember this...

$\fbox{The\;absolute\;value\;is\;a\;number's\;distance\;from\;zero}$

Hope it helps you out! :D

in year 4 the store sold 112% of the total number of scooters sold during the previous three years combined determine the number

Margarita [4]

Answer:

2, 240

Step-by-step explanation:

In the table, the values should be

Year 1 725

Year 2 579

Year 3 696

Since Year 4 sold 112% of the previous 3 years combined, we add 725+579+696=2000. We can find 112% by writing a proportion.

$\frac{112}{100} =\frac{x}{2000}$

We solve through cross multiplication of numerator and denominator of the opposite fraction.

$112(2000)=100(x)\\224000=100x\\2,240=x$
