3/5 * 3/3 = 9/15
4 3/5 = 4 9/15
1/3 * 5/5 = 5/15
2 1/3 = 2 5/15
Subtract = 2 4/15
Answer:

<em>b) Nicki's house is worth $281,143 in 4 years</em>
Step-by-step explanation:
<u>Exponential Growth Function
</u>
The exponential function is commonly used to model natural growing or decaying processes where the change is proportional to the actual quantity.
An exponential growth function is expressed as:
Where:
C(t) is the actual value of the function at time t
Co is the initial value of C at t=0
r is the growth positive rate, expressed in decimal
Nicki paid Co=$245,000 for a house and it's known that home prices increase by r=3.5%=0.035 each year.
a)
Substituting the given values, the equation is:
b) The value of Nicki's house in t=4 years is:
Nicki's house is worth $281,143 in 4 years
Answer:
x = 23/5 and y = 7/20
Step-by-step explanation:
2x + 8y = 12 and 3x - 8y = 11 are two given equations
Now,
<u>Step </u><u>1</u><u>:</u>
2x + 8y = 12 ...(1)
3x - 8y = 11 ...(2)
<u>Step </u><u>2</u><u>:</u>
From equation (2) we get the value of x
i.e.,
3x - 8y = 11
3x = 8y + 11
<em><u>x = 8y + 11/3</u></em>
<u>Step </u><u>3</u><u>:</u>
Now,
Put the value of <u>x = 8y + 11/3</u><u> </u>in equation (1) we get,
i.e.,
2x + 8y = 12
2(8y + 11/3) + 8y = 12
16y + 22/3 + 8y = 12
16y + 22 + 8y(3)/3 = 12
16y + 22 + 24y/3 = 12
16y + 24y + 22 = 12 * 3
40y = 36 - 22
40y = 14
y = 14/40
<em><u>y = 7/20</u></em>
<u>Step </u><u>4</u><u>:</u>
Now,
Substitute the value of <u>y = 7/20</u><u> </u>in equation (2) we get,
i.e.,
3x - 8y = 11
3x - 8(7/20) = 11
3x - 56/20 = 11
3x - 14/5 = 11
3x = 11 + 14/5
3x = 11 * 5 + 14/5
3x = 55 + 14/5
3x = 69/5
x = 69/3 * 5
<em><u>x = 23/5</u></em>
Answer:
D. 62
Step-by-step explanation:
length = 5 in.
width = 3 in.
height = 2 in.
SA formula = 2(L×W) + 2(L×H) + 2(H×W)
2 (5×3) + 2(5×2) + 2(2×3)
