Answer:
[tex]\sqrt{10}[/tex]
Step-by-step explanation:
This is a 45-45-90 triangle whose leg to hypotenuse ratio is 1 / [tex]\sqrt{2}[/tex]
so I set up a proportion of 1 / [tex]\sqrt{2}[/tex] = x / 2 [tex]\sqrt{5}[/tex]
cross-multiply to get [tex]\sqrt{2}[/tex]x = 2[tex]\sqrt{5}[/tex]
x = 2[tex]\sqrt{5}[/tex] / [tex]\sqrt{2}[/tex] and multiply numerator and denominator by [tex]\sqrt{2}[/tex], this is called rationalizing the denominator
lets do
[tex]\\ \sf\longmapsto \sqrt{2}x=2\sqrt{5}[/tex]
[tex]\\ \sf\longmapsto x=\dfrac{2\sqrt{5}}{\sqrt{2}}[/tex]
[tex]\\ \sf\longmapsto x=\sqrt{2}\sqrt{5}[/tex]
[tex]\\ \sf\longmapsto x=\sqrt{2(5)}[/tex]
[tex]\\ \sf\longmapsto x=\sqrt{10}[/tex]

and simplify.
y
=

Answer:
x = -2 and y = 3
Step-by-step explanation:
plug in the x = 3y - 8 into the x for the top equation
so it looks like this...
-3(2y - 8) + 2y = 12
solve
-6y + 24 + 2y = 12
-4y + 24 = 12
-24 -24
-4y = -12
divide bye -4
y = 3
plug in y = 3 on the second equation
x = 2y - 8
x = 2(3) - 8
x = 6 - 8
x = -2

-2(p - 1) = 15 HELPPP PLEASEE
Answers
Answer:
p = -6.5
Step-by-step explanation:
-2(p-1) = 15
p-1 = -7.5
p = -6.5
-2p + 2 = 15
Subtract 2 on both sides.
-2p = 13
Divide by -2 on both sides.
p = -6.5

There are eight employees on the Game Shop's sales teams. Last month, they sold a total of g games. One of the sales teams members, Chris, sold seventeen fewer games than what the team averaged per employee. How many games did Chris sell?
Answers
Answer:
g/8 - 17
Step-by-step explanation:
Number of employees = 8
Total games sold = g
Average sales per employee = total games sold / number of employees = g/8
Chris sold 17 fewer games than the average sales per employee :
Chris sale = average sale per employee - 17
Chris sales = g/8 - 17

Bernice paid $162 in interest on a loan if $1,800 borrowed at 6%. How long did it take her to pay off the loan?
Answers
Answer:
1.5 years.
Step-by-step explanation:
First, converting R percent to r a decimal
r = R/100 = 6%/100 = 0.06 per year,
then, solving our equation
t = 162 / ( 1800 × 0.06 ) = 1.5
t = 1.5 years
The time required to
accumulate simple interest of $ 162.00
from a principal of $ 1,800.00
at an interest rate of 6% per year
is 1.5 years (about 1 years 6 months).
