Answer:
1)
<u><em>k - 5 = m</em></u>
<u><em>n - 3 = s</em></u>
2)
<u><em>Lisa is 17 and Myra is 12</em></u>
__________________________________________________
<u><em>1) </em></u>Key:
brother = b
me = m/n
sister = s
Equation:
m + 5 = b
m - 3 = s
Answer:
b - k = m
n - 3 = s
<u><em>2)</em></u>
L + M = 19
(L + 5) + M = 29
(L + 5 - 5) + m = 24
L + M = 24 / 2 = 12
L = 12 + 5 = 17
M = 12
Lisa will be 17 and Myra is 12
Answer:
It is in the tenths place
Step-by-step explanation:
In the number 9.365, 3 is in the tenths place.
Using it's formula, the surface area of the figure is:
A. S=2332 m²
<h3>What is the surface area of a rectangular prism?</h3>
The surface area of a rectangular prism of dimensions l, w and h is given by:
S = 2(lw + lh + wh)
In this problem, the dimensions are:
35m, 9m, 16m
Hence the surface area of the rectangular prism is:
S = 2(35 x 9 + 35 x 16 + 16 x 9) = 2038 m².
<h3>What is the surface area of a cube?</h3>
The surface area of a cube of side length l is given by:
S = 6l².
In this problem, we have that l = 7 m, hence the surface area is:
S = 6 x 7² = 294 m².
<h3>What is the total surface area?</h3>
The total surface area is the sum of the surface areas, hence:
T = 2038 m² + 294 m² = 2332 m².
Which means that option A is correct.

When you multiply a base with an exponent by a base with an exponent, you add the exponents together. (But you can only combine the exponents when the bases are the same)
For example:
(they have the same base of x)
(you can't combine the exponents because they have different bases of y and x)
![2^2(2^1)=2^{(2+1)}=2^3=8](https://tex.z-dn.net/?f=2%5E2%282%5E1%29%3D2%5E%7B%282%2B1%29%7D%3D2%5E3%3D8)
When you have a negative exponent, you move the base with the negative exponent to the other side of the fraction to make the exponent positive.
For example:
or ![\frac{x^{-3}}{1} =\frac{1}{x^3}](https://tex.z-dn.net/?f=%5Cfrac%7Bx%5E%7B-3%7D%7D%7B1%7D%20%3D%5Cfrac%7B1%7D%7Bx%5E3%7D)
or ![y^{2}](https://tex.z-dn.net/?f=y%5E%7B2%7D)
Add the exponents together
![7^{(3+(-5))}](https://tex.z-dn.net/?f=7%5E%7B%283%2B%28-5%29%29%7D)
Make the exponent positive
Simplify
![\frac{1}{49}](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B49%7D)
