Addition: 70 + 80 = 150. You round 65 up because the ones digit is greater than and the same with 77.
Multiplication: Round up since both ones digits are bigger than 5. 70 x 80= 5600.
Answer:
98
Step-by-step explanation:
I think you can multiply how many are defective in a sample by how much more stuff there is
The general slope-intercept form equation is:

In this case, m=-2 and with the point (4, 10) we can find the value of b:

We found that b = 18, so:
Slope-intercept form is

, where m is the slope and b is the y-intercept.
Here, we first need to distribute the 1/3.

Next, we add 3 to both sides of the equation.
