Answer: In first question answer is -28x+4
In second question required inequality is 3x+100 < 2x-250
Step-by-step explanation:
1. Since, here the given expression is 4(x+5)-8(2+4x)
= 4x+20-16-32x ( By distributive property)
=-28x +4 ( By operating like terms)
2. Here, let the number is x.
Then according to the given question, three times the number of candy is increased by 100
That is, 3x+100
And, 250 less than the two times of the candy
That is, 2x-250
And, 3x+100>2x-250
Which is the required expression.
Hence she should subtract 250 from 2x not 2x from 250.
Answer:
D.
Step-by-step explanation:
We have been given a table that represents the the number of electoral votes California was assigned each decade of the past century. We are asked to find the 3rd quartile of our given data.
The number of votes are: 9, 13, 13, 22, 25, 32, 40, 45, 47, 54, 55.
We will use upper quartile formula to solve our given problem.
, where, n represents the number of elements in the data set.
We can see that our data set has 11 data points, so upon substituting n=11 in above formula we will get,
Now let us count 9th term of our data set. Upon counting our data set from left to right we can see that 9th term of our data set is 47, therefore, 3rd quartile of our given data is 47 and option D is the correct choice.

There are 23 small prints, 264 medium prints ,188 large prints and 42 extra large prints which are being sold by Mr. Carandang.
Given that there is total sales of 1790 prints of one of the drawings by Mr, Caradang. Out of which 1273 unframed prints, 152 were small, 544 were medium. Out of the framed prints 23 were small,42 were extra large. Out of large prints 188 were framed, 496 were unframed.
We are required to find the number of small prints,medium prints, large .extra large in total and total framed print of the drawings.
Total framed print=Small print+Medium print+Large print+Extra large print
=23+264+188+42
=517
Unframed print:
Small=152
Medium=544
Large=496
Extra large=81
Total unframed print=Small+Medium+large+extra large
=152+544+496+81
=1273.
Hence there are 23 small prints, 264 medium prints ,188 large prints and 42 extra large prints which are being sold by Mr. Carandang.
