Answer:
n = 3.8
Step-by-step explanation:
First, we would distribute 0.3 with n and 1.5.
0.3(n - 5) = 0.4 - 0.2n → 0.3n - 1.5 = 0.4 - 0.2n
Next, we can move the number with the variable to one side.
0.2n + 0.3n - 1.5 = 0.4 - 0.2n + 0.2n → 0.2n + 0.3n - 1.5 = 0.4
(Because we added 0.2n to the negative 0.2n on the right side, it cancels it out)
We can also move 1.5 to the right side of the equation as well.
0.2n + 0.3n - 1.5 + 1.5 = 0.4 + 1.5 → 0.2n + 0.3n = 0.4 + 1.5
Then, we combine like terms
0.2n + 0.3n = 0.5n & 0.4 + 1.5 = 1.9 → 0.5n = 1.9
Finally, we divide both sides by 0.5.
n = 3.8
The correct answer is D. 40
Answer: the slope is 1
Step-by-step explanation:
Slope is basically rise over run. Looking at the graph you see it rises one unit and then goes over to the left by one unit. 1÷1 equals 1 so That is your slope.
Answer: Yes
Step-by-step explanation:
When rounding up to the nearest number, you start with tens, then hundreds as the case maybe.
