-3 and -16 multiply to 48 since negatives cancel and add to -19
Option 1.
and option 4.
are equivalent to ![-2(5x-\frac{3}{4} ).](https://tex.z-dn.net/?f=-2%285x-%5Cfrac%7B3%7D%7B4%7D%20%29.)
Step-by-step explanation:
Step 1:
The given expression is expanded as follows.
The -2 is multiplied with the 5x and then the -2 is multiplied with the
.
So the expression becomes as follows;
![-2(5x-\frac{3}{4} ) = (-2)(5x) + (-2)(-\frac{3}{4}).](https://tex.z-dn.net/?f=-2%285x-%5Cfrac%7B3%7D%7B4%7D%20%29%20%3D%20%28-2%29%285x%29%20%2B%20%28-2%29%28-%5Cfrac%7B3%7D%7B4%7D%29.)
This is the first option given so the first expression is equivalent.
Step 2:
![-2(5x-\frac{3}{4} ) = (-2)(5x) + (-2)(-\frac{3}{4}) = -10x + \frac{6}{4} = -10x + \frac{3}{2} .](https://tex.z-dn.net/?f=-2%285x-%5Cfrac%7B3%7D%7B4%7D%20%29%20%3D%20%28-2%29%285x%29%20%2B%20%28-2%29%28-%5Cfrac%7B3%7D%7B4%7D%29%20%3D%20-10x%20%2B%20%5Cfrac%7B6%7D%7B4%7D%20%3D%20-10x%20%2B%20%5Cfrac%7B3%7D%7B2%7D%20.)
Of the other four options, only the fourth expression has the fraction
so the fourth expression is also equivalent.
Expressions 1 and 4 are equivalent to the given expression.
The area of a trapezoid is given by
.. A = (b1 +b2)/2*h
.. = (13 cm +21 cm)/2*(6 cm)
.. = 102 cm^2 . . . . . . . . . . . . . . corresponds to selection A
The number of people who bought tickets for each showing:
![\frac{11550}{50} = 231](https://tex.z-dn.net/?f=%20%5Cfrac%7B11550%7D%7B50%7D%20%20%3D%20231)
Answer: 231
Ok done. Thank to me :>
72*24=1728
1728+16=1744
now u have to deal with the 30 minutes. since its less than an hour, half actually itl be .5
1744.5
