The probability that the card chosen will not be green is 5/7
Regarding question number 47, which is what I can read well ...
Equation 4 (3x-2) ² = 36 It can be solved in the following way:
-Apply distributive property
4 (9x ²-12x +4) = 36
-We order the terms and equalize to zero
36x² -48x +16 -36 = 0
36 x ² -48x -20 = 0
The roots of this equation are
(-48 + √(48 ²-4 ×36 × -20)) / 2 ×36
and
(-48 - √(48 ²-4 × 36 ×-20)) / 2 ×36
Finally the solution is:
option C
x = -1 / 3
x = 5/3
Answer:
x ≤ 7.25
Step-by-step explanation:
1) 
≤ 
<u>Distribute</u> <em>5</em> through the parenthesis.
2) ≤ 
Move the <u>variable</u> to the left side and change it's sign.
3) 
≤ 
Move the <u>constant</u> to the right side and change it's sign.
4) 
≤ 
Subtract the <u>like terms</u>.
5) 
≤ 
Divide both sides of the inequality by <em>-2</em>.
6) 
≤ 
Answer:
30 is the correct answer because 3times 10 =30 5 times 6 is 30 and 10 times3 is also 30
Answer:
x=3
Step-by-step explanation:
1. Rearrange terms
1 - 6x = -17
-6x + 1 = -17
2. Subtract 1 from both sides of the equation (we want to get rid of 1)
3. Simplify
In the end, you should get x=3.
