Answer:
2 cups of clay
Step-by-step explanation:
Given data
we are given that 6 cups of water for every 12 cups of clay
i.e
12 cups of clay require 6 cups of water
4 cups of clay will require x cups of water
cross multiply
12x= 4*6
12x= 24
divide both sides by 12
x= 24/12
x= 2cups
Hence 4 cups of water will require 2 cups of clay

Answer:
y = x - 5
Step-by-step explanation:
Note that when x increases from zero (0) to 5, an increase of 5 units, y increases from -5 to 0, an increase of 5 units.
Thus, the slope of this line is m = rise / run = 5/5 = 1.
The y-intercept is clearly discernable and is (0, -5).
Thus, using the slope-intercept form of the equation of a straight line:
y = 1x - 5, or just y = x - 5.
Answer:
D. 160
Step-by-step explanation:
The sum of the sequence 1, 2, 3, 4, ... , n is n(n + 1)/2.
Here, you have the sum of 4(1, 2, 3, 4, ... , n), so the sum is 4[n(n + 1)/2]
In this case, the first term is 0, so the last term is the 8th term of the sequence above, so n = 8
4[n(n + 1)/2)] =
= 4[8(9)/2]
= 4[72/2]
= 4(36)
= 144
The closest answer is D. 160
