<span>False.
-2(3x - 4) distributes to become -6x + 8
Thus, it is easy to tell it is false:
-2(3x - 4)= -6x - 8
-6x + 8 = -6x - 8
Add 6x to both sides;
8 </span>≠<span> -8</span>
Answer:
ages would no longer get larger as the mouse hovers over them. The transition would happen over 10s, since this is the default duration.
Step-by-step explanation:
Answer:
x = -3
Step-by-step explanation:
You will have to distribute first
7 -2x -11 + 9 -3x = 20
Then, combine you like terms
-2x -3x = -5x
7 -11 +9 =5
Then you write it as an equation
-5x +5 = 20
Next you will want to have x by itself which means you have to get rid of the 5 by substracting 5 on each side (opposite of addition is substraction)
-5x = 15
Then you divide each side by -5 ( opposite of multiplication is division)
x= -3
Hope this helped :D
Answer: 0.81859
Step-by-step explanation:
Using the formula ;
Z = 
where u = mean
Therefore the probability that a student will finish the test between 40 and 70 will be :
P ( 40≤X≤70 ) = P(X≤70) - P(X≤40)
P ( 60-40/10) , P( 60 - 70 / 10)
= 2 , -1
= P (Z ≤ 2) - P( Z ≤ -1 )
From normal table , we have
0.97725 - 0.15866
Therefore the probability that a student will finish the test between 40 and 70 minutes = 0.81859
Step-by-step explanation: In order to decide whether the given fractions are equivalent, first write each fraction in lowest terms. Remember, a fraction is written in lowest terms if the greatest common factor of the numerator and the denominator is 1.
For our first fraction which is 3/4, the greatest common factor of 3 and 4 is 1, the fraction is already in lowest terms.
For our second fraction however, since the greatest common factor of 6 and 8 is 2, we must divide both the numerator and denominator by 2 which gives us 3/4.
3/4 = 3/4 which means these fractions are equivalent.
3/4 and 6/8 are equivalent because if you reduce 6/8 in lowest terms, you end up with the fraction 3/4.
