Steven gained 100 points.

To calculate the gain or lose of any 2 numbers, always do

Final - Initial

So,

-50 - -150

Is like saying

I have negative 50, and I take away negative 150.

Taking away negative numbers is just addition.

-50 + 150 = 100

Answer:   \bold{-7+2\sqrt{14}+5\sqrt{7}-10\sqrt{2}}

<u>Step-by-step explanation:</u>

\dfrac{\sqrt7-5}{\sqrt7+\sqrt8}\bigg(\dfrac{\sqrt7-\sqrt8}{\sqrt7-\sqrt8}\bigg)=\dfrac{7-2\sqrt{14}-5\sqrt{7}+10\sqrt2}{7-8}=\dfrac{7-2\sqrt{14}-5\sqrt{7}+10\sqrt2}{-1}\\\\\\=\boxed{-7+2\sqrt{14}+5\sqrt{7}-10\sqrt2}

WILL GIVE BRAINLEST!!! solve the triangle and answers to the nearest tenth.
sineoko [7]

Answer:

Angle A is 29 degress Angle B is 61 Angle C is 90

Side AB is 5.8 Side BC is 2.8 and  Side AC is 5.1

Step-by-step explanation:

Angle A is found using triangle interior theorem.

I found side AC by using law of sines

b/sin b= c/sin c

x/sin 61= 5.8/sin 90( which equal 1)

x=5.1

I found side BC by using pythagoren theorem.

a^2 + b^2=c^2

5.1^2+ b^2=5.8^2

26.01+b^2=36.64

b^2=7.63

b=approx 2.8.

A bookkeeper has a balance of $83.92. If she collects $76.75
kotegsom [21]

Answer:

The bookkeeper already has a balance of 83.92.  She collects 76.75 so that's 83.92+76.75 which equals to 160.67.  Then she pays out 38.58 so that's a deduction to what she already has.  160.67-38.58=122.09.

SO the bookkeeper has $122.09 left.
