1. Carmen is playing with blocks. She arranges stacks of blocks so that each successive level of blocks has
1 fewer block than the level below it and the top level
has 1 block. Such a stack with 3 levels is shown below.
Carmen wants to make such a stack with 12 levels.
How many blocks would she use to build this stack?
level 1
level 2
level 3
A. 66
B. 78
C. 132
D. 144

answer: the answer is 127 degrees

stew reads at the fastest rate of 265 words per minute.

step-by-step explanation:

it's a given that felicia reads at 260 word per minute and on connie's graph we can see that she reads 200 words per minute. since stew's table tells us that he read 795 in 3 minutes, we can divide 795 by 3 to find out how many words he reads per minute.

795/3 = 265

stew reads 265 words per minute - he reads at the fastest rate since felecia reads at 260 words per minute and connie reads at 200 words per minute.

stew (265) > felecia (260) > connie (200)

the answer is d

the answer is in the first quadrant, which make the y-int positive.

since the dots are going down, therefore the correlation is negative

i hope it is right.

x = -4

step-by-step explanation:

- 20 - 4(x + 3) = 4x

=> -20 - 4x - 12 = 4x

=> - 32 -4x = 4x

=> -32 = 4x + 4x

=> - 32 = 8x

=> -32/8 = x

=> -4 = x
