Answer:

Step-by-step explanation:
what are we sloving
we have the equation
![\frac{x}{3}+5=8](https://tex.z-dn.net/?f=%5Cfrac%7Bx%7D%7B3%7D%2B5%3D8)
Solve for x
That means ----> isolate the variable x
step 1
Subtract 5 on both sides
![\begin{gathered} \frac{x}{3}+5-5=8-5 \\ \\ \frac{x}{3}=3 \end{gathered}](https://tex.z-dn.net/?f=%5Cbegin%7Bgathered%7D%20%5Cfrac%7Bx%7D%7B3%7D%2B5-5%3D8-5%20%5C%5C%20%20%5C%5C%20%5Cfrac%7Bx%7D%7B3%7D%3D3%20%5Cend%7Bgathered%7D)
step 3
Multiply by 3 on both sides
![\begin{gathered} \frac{x}{3}*3=3*3 \\ x=9 \end{gathered}](https://tex.z-dn.net/?f=%5Cbegin%7Bgathered%7D%20%5Cfrac%7Bx%7D%7B3%7D%2A3%3D3%2A3%20%5C%5C%20x%3D9%20%5Cend%7Bgathered%7D)
<h2>The answer is x=9</h2>
Step-by-step explanation:
1. y=(x-2)²-9
Using Formula (a-b)²=a²-2ab=b²
y=(x²-4x+4)-9
y=x²-4x-5
Using Mid term Break
y=x²-5x+x-5
y=x(x-5)+1 (x-5)
y=(x+1)(x-5)
2. y= -(x-5)²+16
Using the same formula as above
y= -(x²-10x+25)+16
y= -x²+10x-25+16
y= -x²+10x -9
Taking (-) as Common
y= -(x²-10x+9)
y= -(x²-9x-x+9)
y= -[x(x-9)-1(x-9)]
y= -(x-1)(x-9)
You will use the formula to calculate simple interest for each period of time and then subtract the two amounts to find how much Ward will save.
I=prt
I = 20000 x 0.025 x 3
I = $1500 over 3 years
I = 20000 x 0.025 x 5
I = $2500 over 5 years
$2500-$1500 = $1000 in savings
Answer:
x = ![\sqrt{3}](https://tex.z-dn.net/?f=%5Csqrt%7B3%7D)
Step-by-step explanation:
the ratio of side to hypotenuse in a right triangle is 1 : ![\sqrt{2}](https://tex.z-dn.net/?f=%5Csqrt%7B2%7D)
in this problem we can use 'x' in place of 1 and
in place of
to create a proportion like this:
1/x =
/![\sqrt{6}](https://tex.z-dn.net/?f=%5Csqrt%7B6%7D)
cross-multiply to get:
·x = ![\sqrt{6}](https://tex.z-dn.net/?f=%5Csqrt%7B6%7D)
x = ![\frac{\sqrt{6}}{\sqrt{2}}](https://tex.z-dn.net/?f=%5Cfrac%7B%5Csqrt%7B6%7D%7D%7B%5Csqrt%7B2%7D%7D)
x = ![\sqrt{3}](https://tex.z-dn.net/?f=%5Csqrt%7B3%7D)
