<span>13x−4=−9(4+3x)+12 Given
13x−4=−36−27x+12 distributive property [-9 (4 + 3x) + 12 = -36 -27x]
13x−4=−24−27x Subtraction property [ -36 + 12 ] = -24
13x + 27x = -24 + 4 collecting like terms
40x=−20 </span> Addition Property of Equality
<span>as 13x + 27 x = 40x and -24 + 4 = -20
x=−1/2 Division Property of Equality
40x / 40 = x and 20 /40 = 1/2 </span>
Step-by-step explanation:
3.4
Answer:
The probability mass function of random variable X which represents the number of blue marbles drawn in 2 draws with replacement.
X | P(X)
0 | 0.390625
1 | 0.46875
2 | 0.140625
The probability of drawing exactly one blue marble = 0.46875
0.46875 as a simplified fraction is ------ 15/32
Step-by-step explanation:
A=30
Multiply base times height and then divide by 1/2
(3 3/4)(4)=15
15/(1/2) = 30
Why we need to classify it??It has it's won identity..
However, it is a natural number..
