Answer:
7.5
Step-by-step explanation:
Lets define what we're looking for, the "number", to be equal to x.
number = x
Following the questions hints:
" The sum of twice a number and three times a number"
(2x) + (3x)
is (which means equals to basically)
" triple the quantity of five more than a number"
3(x+5)
We connect all of this to find the number and get:
(2x) + (3x) = 3(x+5)
5x = 3x + 15
5x -3x = 15
2x = 15
x = 15/2
x = 7.5
Answer:
Step-by-step explanation:
The equation for a circle in standard form is , where h and k are the coordinates of the center. Our center has an h value of -2 and a k value of -3 with an r value of 3. Fitting those values into our standard form of a circle we have . Subtracting a negative is the same as adding, and squaring the right side gives us 9, so the equation is . Third choice from the top.
Answer:
(A/21h) -c
Step-by-step explanation:
A= 21h(c+d)
A/21h = c+d
(A/21h) -c =d

Answer:
Step-by-step explanation:
Simplifying
m = 10x + -1x
<em>Combine like terms</em>: 10x + -1x = 9x
m = 9x
Solving
m = 9x
Solving for variable 'm'.
Move all terms containing m to the left, all other terms to the right.
Simplifying
m = 9x
Hope this helps :-D
