Answer:
[tex]r = 13[/tex]
Step-by-step explanation:
[tex](8r + 5) + (5r + 6) = 180 \\ 13r + 11 = 180 \\ 13r = 180 - 11 \\ 13r = 169 \\ \\ r = \frac{169}{13} \\ \\ r = 13[/tex]

Step-by-step explanation:
The equation of the line is y = ( 4/3 )x + 2.
What is an equation of a line?An equation of the line is defined as a linear equation having a degree of one. The equation of the line contains two variables x and y. And the third parameter is the slope of the line which represents the elevation of the line.
Given that the equation is parallel the line y = ( 4 / 3 )x + 8 and passes through the point ( -6 , -6 ).
The general equation of the line is
y = mx + c
The slope of the required line will be the same as the slope of the line parallel to the required line.
m = ( 4 / 3 )
The equation of the line will be written:-
y = mx + c
y = ( 4 / 3 )x + c
-6 = ( 4 / 3 ) x -6 + c
c = 2
y = ( 4/3 )x + 2
Therefore, the equation of the line is y = ( 4/3 )x + 2.

x to the second power plus 24 to the second power equals 30 to the second power .
Answer:
x = 18 or -18
Step-by-step explanation:
x^2 + 24^2 = 30^2
simplify
x^2 + 576 = 900
subtract 576 from both sides
x^2 = 324
Take square root of 324
+/- √324
x = 18 x = -18
18 or -18 is the answer
Mai sold t- shirts at a festival and made a profit of $83. She made $5 for each t-shirts she sold. Her total expenses were. How many t-shirts did she sell

Step-by-step explanation:
I think iv seen this question somewhere so did u forget to put 22?
Here is the explaination if u did...
5T -22 = 83
revenue minus expense = profit
5T = 83+22 = 105
T = 105/5 = 21 T shirts sold

First, notice that (a + 1/a)2 = 42 = 16. But also, (a + 1/a)2 = a2 + 2a(1/a) + 1/a2 = a2 + 2 + 1/a2 = a2 + 1/a2 + 2
So a2 + 1/a2 + 2 = 16, so a2 + 1/a2 = 14.
Now, do that again...
(a2 + 1/a2)2 = 142 = 196, but also (a2 + 1/a2)2 = a4 + 2(a2)(1/a2) + 1/a4 = a4 + 2 + 1/a4 = a4 + 1/a4 + 2
So a4 + 1/a4 + 2 = 196, so a4 + 1/a4 = 194
You can see the pattern... E.g., a8 + 1/a8 = 1942 - 2, etc.

Answer:
25 and 55
Step-by-step explanation:
Let's call the larger number L and the smaller S
L = 5 + 2×S
And the sum is:
L + S = 80 Subtract S in both sides:
L = 80 - S
Now, substitute this value of L in the first equation:
80 - S = 5 + 2×S Add S in both sides:
80 = 5 + 2×S + S
80 = 5 + 3S Subtract 5 in both sides
75 = 3S Divide both sides by 3
25 = S
We find the value of S, and now we substitute it in the second equation to find the value of L:
L = 80 - 25
L = 55

Answer:
[tex]f(x) = 2x + 1 \\ g(x) = {x}^{2} - 7 \\ (f + g)(x) = f(x) + g(x) \\ (f + g)(x) = (2x + 1) + ( {x}^{2} - 7) \\ (f + g)(x) = 2x + 1 + {x}^{2} - 7 \\ \boxed{ (f + g)(x) = {x}^{2} + 2x - 6}[/tex]
