Step-by-step explanation:
9(p-4) = -18
9p - 36 = -18
9p = -18 + 36
9p = 18
p= 18/9
p = 2
Check:
9 ( 2 - 4 ) = - 18
9 (-2) = - 18
- 18 = - 18

If you apply the linear combination method to the system like:
<span>4(.25x + .5y = 3.75) → x + 2y = 15
(4x – 8y = 12) → x – 2y = 3
2x = 18
Then you can be sure that the solution of all this system is: (9,3). Hope this si what you were looking for</span>
The answer is C. All calculations of a cone or the cone equal up to 353.77. Hope this helps!
Answer:
B
Step-by-step explanation:
The given equations satisfy the given conditions. There are 2 equations and 2 unknowns, so a certain solution can be found.
This can be solved using substitution,
Substituting eqn 2 to eqn 1:
2(2y – 10) + 3y =1240
Simplifying,
y = 180
x = 350
