Answer:
240+30x
Step-by-step explanation:
240+30x because you multiply 30 x 8 and get 240 plus 30 x X and get 30x
Answer:
Step-by-step explanation:
if you have one side =2/7
area = (2/7)^2=4/49 m^2
Answer:
(13.4,-4.2)
Step-by-step explanation:
The given system has equations:
![20x - 5y = 289](https://tex.z-dn.net/?f=20x%20-%205y%20%3D%20289)
![22x + 9y = 257](https://tex.z-dn.net/?f=22x%20%2B%209y%20%3D%20257)
Multiply the top equation by 9 and
Multiply the second equation by 5:
![180x - 45y = 2601](https://tex.z-dn.net/?f=180x%20-%2045y%20%3D%202601)
![110x + 45y = 1285](https://tex.z-dn.net/?f=110x%20%2B%2045y%20%3D%201285)
Add the new equations.
![290x = 3886](https://tex.z-dn.net/?f=290x%20%3D%203886)
![x = 13.4](https://tex.z-dn.net/?f=x%20%3D%2013.4)
Put this into the first equation to get:
![20(13.4) - 5y = 289 \\ 268 - 5y = 289 \\ - 5y = 21 \\ y = - 4.2](https://tex.z-dn.net/?f=20%2813.4%29%20-%205y%20%3D%20289%20%5C%5C%20268%20-%205y%20%3D%20289%20%5C%5C%20%20-%20%205y%20%3D%2021%20%5C%5C%20y%20%3D%20%20-%204.2)
Answer:
M(t) = M(16 - 2·t)
Step-by-step explanation:
The function is just formed by using the concept of composite functions.
B is cups of blueberries, and n is cups of blueberries,
So by substituting values the required equations formed are given by :
B(t) = 2·(8 - t)
M(n) = 12·n
n = B(t)
M(t) = M(n)
= M(B(t))
= M(2·(8 - t))
= M(16 - 2·t)
Therefore, this is the required function muffins M
