<span>It's easy enough. Solving looks like that: p(roll of 8)+p(roll of 12) =</span>

Hope everything is clear.
Answer:
True
Step-by-step explanation:
Answer:
d. 9x + 63 and 63 square feet
Step-by-step explanation:
Given
Original


Extended



Required
Determine an expression and the value of the extended area
First, we calculate the area of the original desk


From the given parameters, we have:
--- area of the new surface
Open bracket

The area of the new surface is the summation of the area of the original desk and the area of the extended portion (E)
So:

Make E the subject



Hence, the area of the extended portion is 63
Answer:
8:3
Step-by-step explanation:
He uses 8 cups of water and 3 cups of drink mix, so therefore, the ratio is 8:3
Direct variation in mathematics is when two numbers are written in an equation where one of the numbers multiplied by a constant term to equal the other.
In the table in the equation, we see direct variation.
<u>X</u> <u>Y
</u><u></u>1 7
2 14
3 21
4 28
We can find the constant of the variation by dividing y by x. This constant should remain the same for all terms of x in the table with their corresponding y values.
y/x
7/1=7
14/2=7
21/3=7
28/4=7
As we can see, the values in the table all share a direct variation between x and y with the value 7.
This can be expressed in an equation: y = 7x.
