Answer:
8
Step-by-step explanation:
Multiply 11 by 2 to get to 22; do the same to 4
4x - (9 - 3x) = 8x - 1
4x - (9) - -(3x) = 8x - 1
4x - 9 + 3x = 8x - 1
7x - 9 = 8x - 1 (-8x from each side)
-x - 9 = -1 (+9 to each)
-x = 8 (divide -1 from each side)
x = -8
Answer:
66
Step-by-step explanation:
57 x 2= 114
180-114= 66
Answer:
-20x+8
Step-by-step explanation:
Step 1: rearrange the equation
16x^2 - 3x^2 - 7x - 13x +8
Step 2: solve the equation
16x^2 - 3x^2 = 13x^2
-7x - 13x = -20x
(the +8 will stay the same)
so when we put it all together it gives us
13x^2 - 20x + 8
Here are the answers to problem 1..
a) 11
b) 5/36
c) 25 Times because 7 has a probability of 16.667%
d) 25 Times because 10, 11, and 12 have a probability sum of 16.667% ironically...
Hope this helps. :)
