Answer: Stephanie read more than 7 books because 8 points for 9 books each is equal to 72 points, which is the total amount of books she read.
Step-by-step explanation:
72 ÷ 8 × 9
x = 9
Hope this helped! :D
Answer:
the answer i think would be f(x)=7
Step-by-step explanation:
<u>Answer
</u>
-1 x + 2y = 4
<u>Explanation
</u>
The first step is to get the gradient of the line.
The two points in the line are; (4,0) and (0,2).
slope = (2 - 0)/(0 - 4)
= 2/-4
= -1/2
To get the function we use one of the point (0,2) and a general point (x,y).
1/2 = (y - 2)/(x - 0)
1/2 = (y - 2)/x
(1/2)x = y -2
x = 2y - 4
x - 2y = -4
-1 x + 2y = 4
Hey there!
Let's set up our expression:
(7a-6b+7)-(8a-2)
In order to simplify, we can use that subtraction sign and distribute it, using the distributive property. We have:
7a-6b+7-8a+2
Notice how it's plus two, because a negative times a negative two is a positive two. Now, it's a matter of finding the like terms and adding or subtracting them. These like terms can either have no variable, or have different coefficients but the same variable. That means our like terms are the 7a and -8a, and the 7 and 2. There's no like term for the 6b. That means we have:
(7a-8a) - 6b + (7+2) =
-a - 6b + 9

Step-by-step explanation:
Volume of the cylinder = πr²h
π(2.1)² (6) = 83.12 cm³
volume of prism = ½bhl
2(10)(3.5) = 70cm³
Volume of cylinder is more than that of prism.
Therefore, Cylinder holds more water
