Answer:
k = -21
Step-by-step explanation:
9/ (2k-3) = 4/(k+1)
Using cross products
9 * (k+1) = 4(2k-3)
Distribute
9k+9 = 8k -12
Subtract 8k from each side
9k-8k +9 = 8k-8k-12
k+9 = -12
Subtract 9 from each side
k+9-9 = -12-9
k = -21
Answer:
4 weeks
Step-by-step explanation:
Company A charges $40 per week and a one time fee of $25
Company B charges $35 per week and a one time fee of $45
Therefore the number of weeks required for both companies to arrive at the same cost can be calculated as follows
Company A = 45 + 35×4
= 45 + 140
= 185
Company B = 25 + 40×4
= 25 + 160
= 185
Hence it will cost both companies 4 weeks
Answer:
The width of the trampoline is 8 feet.
Step-by-step explanation:
Area of rectangular trampoline = 112
let the width of the trampoline be represented by w, but,
length = w + 6
Given that the situation has been represented by the equation;
+ 6w - 112 = 0
+ 14w - 8w - 112 = 0
( + 14w) - (8w + 112)
w(w + 14) - 8(w + 14)
(w + 14)(w - 8)
So that;
w + 14 = 0 or w - 8 = 0
w = -14 or w = 8
Thus, w = 8
The width of the trampoline is 8 feet.
Answer:
the number of cookies ordered
Step-by-step explanation:
When an equation is written in the form ...
(left variable) = (some expression involving one or more right variables)
we usually describe the "left variable" as the "dependent variable" and the "one or more right variables" as the "independent variable(s)".
Here, the equation is given as ...
C = 3s + 30
__
This tells you C is the dependent variable, and s is the independent variable. The description also says "C is the number of cookies." Since you know that the dependent variable is the number of cookies, you can answer the question ...
the dependent quantity is the number of cookies ordered. (matches the first choice)
