It is 198.97. So the first thing you have to do is multiply 189.50 by .05.
Then you add that to 189.50 and thats how you get 198.97

It would be $947.50 because you would multiply $189.50 by 0.05.

Debora [2.8K]

1x - 4 = 2x
(minus the 1x from the left to cancel it out and minus it to other side making the 2x a 1x or just x)⤵️

-4 = x

and that is the answer

Given:

$\frac{\frac{p^2-p-2}{2p^2+3p+1}}{\frac{p^2-3p+2}{p^2+5p-6}}$

Simplify in the from of numerators and denominators.

$\frac{p^2-p-2}{2p^2+3p+1}\times\frac{p^2+5p-6}{p^2-3p+2}$

solve the inequality is:

Lisa wants to use her calculator to square a two-digit positive integer, but she accidentally enters the tens digit incorrectly.

Answer: Correct two digit number= 24

Step-by-step explanation:

Let

x= tens digit (wrong one)

and y= zeroes digit

and z= tens digit (right one)

Now according to the statement,

(10x+y)² - (10z+y)² = 2340

Simplifying this we get

(x-z)(5x+y+5z)= 117= 1 * 3 * 3 * 13

So it could either be

x-z=1 or x-z=3

If we take the x-z=1

then 5x+y+5z=117

which is not possible as maximum value we can get from this is 99.

This leaves us with x-z=3

so 5x+y+5z= 39

Put x=3+z

We get,

y+10z= 24

Now as y and z both are single digits so the only possible numbers to fit these are y=4 and z=2.

Put z=2 in x=3+z , we get x=5

So the numbers become 10x+y= 54

and 10z+y= 24

Their sum is 54+24=78

Check

54²-24²= 2340 so it is correct.
