Answer:
32 and 40
Step-by-step explanation:
Let's call the smaller number x. If the smaller number is x, the equation for this problem is 2x + 8 = 72
Equation:
2x + 8 = 72
2x = 64
x = 32
So now we know the smaller number is 32, so now add 8 and we get 40.
Therefore the 2 numbers are 32 and 40
Answer:
m = -4
Step-by-step explanation:
We are given that a line intersects the points (-2, 9) and (3, -11).
We want to write the slope of this line.
The slope (m) can be found using the formula , where and are points.
Even though we have everything we need to calculate the slope, let's label the values of the points to avoid any confusion & mistakes.
Now substitute these values into the formula (remember that the formula has subtraction).
m=
m=
Simplify.
m=
Subtract the values on top.
m=
Now add the values on the bottom together.
m=
Now divide -20 by 5.
<u>m = -4</u>
Answer: 5/10 or 1/2
Step-by-step explanation:
To find how much longer, subtract to get the difference:
9/10 - 4/10 = 5/10
5/10 simplified is 1/2
