Answer: #20, x = 3
#21, x = 1/2
Step-by-step explanation:
#20) x + 4 + x + 2+ x + 5 = x + 3 +x+3+x+1+x+1
3x + 11 = 4x + 8
<u>-3x -3x</u>
11= x + 8
<u> - 8 - 8</u>
3 = x
#21) 12x(5) = 6x + 9 + x + 10 + x + 7
60x =8x + 26
<u> -8x -8x</u>
52x = 26
divide both sides by 52
x = 1/2
There all log base 3, the base won't matter as long as they're all the same.
log(x^2/y)=2log(x)-log(y)=2(4.5)-3=6
Answer: c. 6
Remark
I take it MO is bisected by N. If it isn't we need some clue how to proceed.
Step One
Solve for x
9x = 2(x + 7) remove the brackets.
9x = 2x + 14 Subtract 2x from both sides.
9x - 2x = 14
7x = 14 Divide by 7
x = 14/7
x = 2
Step Two
Find MO
2(x + 7) + 9x = MO
2(2 + 7) + 9(2) = MO
2*9 + 9*2 = MO
18 + 18 = MO
36 = MO <<<<< Answer
Answer:
Im pretty sure it's 168
Step-by-step explanation:]
9 x 14 = 126
126 ÷ 0.75 = 168
Answer: P(draw a 10) = 1/10
-----
P(draw a 10 ten times with replacement) = (1/10)^10 = 1/10000000000
