Answer:
74/100 OR 37/50
Step-by-step explanation:
First add everyone together since its asking for no cold / everyone.
41 + 15 + 12 + 5 + 21 + 6 = 100
Then add to gether the total of people without a cold.
41 + 12 + 21 = 74
Next you just put the ratio in order which in this case would be no cold / everyone then if possible simplify.
74/100 = 37/50
A
The first equation has slope 6 and y intercept -4. I'd plot y intercept (0,-4) and (1,2), and connect the dots and extend for the first line.
The second equation has slope 5 and y intercept -3. I'd plot y intercept (0,-3) and (1,2), and connect the dots and extend for the second line.
We stumbled on the solution, both lines contain (1,2)
B
I don't like the graphing. This is algebra, not connect the dots.
We have two equations for y, we equate them to find the x where they meet.
6x - 4 = 5x - 3
6x - 5x = -3 + 4
x = 1
y = 6(1) - 4 = 2
Check: y = 5(1) - 3 = 2, good
Answer: (1, 2)
Answer:
5(k + 1) and 5k + 5
Step-by-step explanation:
The easiest way to do this is to pick any number to substitute in for the variable <em>k </em>for ALL of the expressions, and find the expressions that equal the same as the first expression being compared.
For example, lets just make <em>k </em>equal 1 to make things easy. Plug 1 into <em>k</em> into the first expression. 2k + 2 + k + 3 + 2k → 2(1) + 2 + (1) + 3 + 2(1) = 10.
Now we do the same to the rest of the expressions and see which ones ALSO equal 10.
5(k + 1) → 5(1 + 1) = 10
5k + 5 → 5(1) + 5 = 10
5 + k^5 → 5 + (1)^5 = 6
5k^5 → 5(1)^5 = 5
