The answer is n = -4. To get that, is to multiply the whole thing by 2 and then solve.
2×(n/2) + 5=3
(Canceled out the 2) n +10 = 6
N = -4 (by subtracting 10)
Answer:
w = 1.6
Step-by-step explanation:
Given w varies inversely as
then the equation relating them is
w =
← k is the constant of variation
To find k use the condition when x = 4, w = 4
k = w
= 4 ×
= 4 × 2 = 8
w =
← equation of variation
When x = 25, then
w =
=
= 1.6
If the ratio of girls to boys in Mr. Hansen's class is 4:5, and the ratio of girls to boys in Ms. Luna's class is 8:10, then the equation that correctly compares the ratio of both Mr. Hansen's class and Ms. Luna's class are 4/5 = 8/10.
Answer:
Two sets are called disjoint if they have no elements in common. For example:
The sets S = { 2, 4, 6, 8 } and T = { 1, 3, 5, 7 } are disjoint.
Another way to define disjoint sets is to say that their intersection is the empty set,
Two sets A and B are disjoint if A ∩ B = 0.
In the example above,
S ∩ T = ∅ because no number lies in both sets.

Answer:
. B. For every 8 french fries, there is 1 packet of ketchup
Step-by-step explanation:
THIS ARE THE OPTIONS FOR THE QUESTION
A. There are 7 more french fries than packets of ketchup. B. For every 8 french fries, there is 1 packet of ketchup. C. For every 8 packets of ketchup, there is 1 french fry. D. There are 8 more french fries than packets of ketchup.
Ratio expresses quotient of two mathematical expressions. It gives relationship in term of quantity, amount existing between two or more things. From the question, it shows that when ever there is 8 french fries, there would be 1 packet of ketchup. I.e french fries and ketchup are in ratio of 8:1
