Answer:
c = 2
Step-by-step explanation:
Since 16 is over the variable c, first multiply both sides by c so the variable is not in the denominator of the fraction.
16/c(c) = 8(c)
16 = 8c Next, divide both sides by 8 to solve for c.
c = 2
A word problem is used to solve problems in mathematics without the explicit use of equations initially.
<h3>What is a Word Problem?</h3>
This refers to the use of words to generate an equation that can be solved by mathematical means.
Hence, we can see that because the question is incomplete, we can infer that there is a relationship that exists between Dr. White, Dr. Black, Dr. Brown, and a woman that does not have brown hair, and equality would be used to solve it.

8x + 6y = 10 ----------- (1)
5x - 3y = 2.2 ---------- (2)
(2) x 2:
10 x - 6y = 4.4 --------(2a)
(2a) + (1)
18x = 14.4
x = 1.8 ------- sub into (1)
8 (1.8) + 6y = 10
14.4 + 6y = 10
6y = 10 - 14.4
6y = - 4.4
y = - 0.73
There is 1 set of solution to it. (Answer C)
Answer:
breadth: 3 m and area of rectangle: 27 m²
explanation:
part A:
perimeter of rectangle: 2 ( length + breadth )
using the formula:
24 = 2 ( 9 + breadth )
9 + breadth = 12
breadth = 3 m
part B:
area of the rectangle = length * breadth
using the formula:
9 * 3
27 m²
