So 53 + 60 is 113...
so x = 180-113
the value of x is 67

Answer:

4a+5a+7b-b

the first thing is to put the like terms together

Step-by-step explanation:

then add or subtract as given after pairing.

Therefore;

our answer is; 9a+6b

since it is factorisable we can further write it this way; 3(3a+2b)

q2) 6c+4d-c-7d

we first put the like terms together

6c-c+4d-7d

we then add and subtract

5c-3d

since our answer is not factorisable we leavem;

5c-3d as our final answer

40 points fast For the following set of test scores, identify:

myrzilka [38]

Answer:

The measure of center would this student want his teacher to use is the

median $= {\bf 75}$

Mean $= {\bf 5}$ , Mode $={\bf 82}$ , Range $={\bf40}$ and Interquartile Range $= {\bf 32}$

Step-by-step explanation:

Given Data set $= 50,55,70,75,82,82,90$

Number of elements in data set $= 7$

To find Mean

The ‘Mean” is the average of a set of numbers.

The "Mean" is computed by adding all of the numbers in the data together and dividing by the number of elements contained in the data set.

Mean $= \frac{50 +55 +70 + 75 + 82 + 82 + 90} {7 }$

Mean $= \frac{504}{7}$

Mean $= 5$

Median

The “Median” is the middle value of a set of ordered numbers.

Therefore Median $=75$

Mode

The "Mode" for a set of data is the value that occurs most often.

It is not uncommon for a data set to have more than one mode. This happens when two or more elements occur with equal frequency in the data set.

Therefore Mode $=82$

Range

The "Range" is the difference between the largest value and smallest value in a set of data.

Range $= 90-50$

Range $= 40$

Interquartile Range

The “Interquartile Range” is the difference between smallest value and the largest value of the middle 50% of a set of data.

The "Interquartile Range" is from Q1 to Q3:

To find the interquartile range of a set of data:

The cut the list into four equal parts

. The quartiles are the “cuts”

The interquartile range is the distance between the two middle sets of data

Interquartile Range $= Q_3-Q_1$

Interquartile Range $= 82-50$

Interquartile Range $= 32$

The price of the box of 15 stickers is $6. The price of the box of 25 stickers is $8. All prices are without tax, and the price

REY [17]

Answer:

$y=0.2x+3$

Step-by-step explanation:

Let

x ----> the number of stickers

y ----> the price of the boxes

we have the points

$A(15,6),B(25,8)$

Find the slope

$m=(8-6)/(25-15)$

$m=2/10=0.20$

Find the equation of the line into point slope form

The equation is equal to

$y-y1=m(x-x1)$

substitute the value of m and the point A

$y-6=0.2(x-15)$

$y=0.2x-3+6$

$y=0.2x+3$ ----> linear equation that represent the situation
