Write a real world problem that you can model with the two step equation 5x+7=10. then solve the problem

x=0.6

Step-by-step explanation:

One problem may be: Jane spent $ 10 on candy for her daughter. This was 7 times more than 5 times what she spent the last time she bought candy. How much did you spend last time?

5*x+7=10

First, you have to know that there are two pairs of inverse operations: addition and subtraction, multiplication and division.

Formally, to solve an equation we must isolate the unknown x.

For that, you change the numbers from one side of an equation to the other. For that, first the number 7, which is adding on the left side, will go to the right side of the equation with the opposite operation, the subtraction:

5*x=10-7

5*x=3

Then, to isolate "x", as 5 is multiplying, go to the other side of the equation by dividing.

x=0.6

see below

step-by-step explanation:

7.   there are 10 data points in the set.   the middle point is between 5 and 6.   the middle point in the top half is 8   and the middle point in the bottom half is 3. to find the iqr , take point 8 and subtract point 3

mid term   point 8 = 100   point 3 = 88

iqr = 100-88 = 12

final   point 8 = 93   point 3 = 78

iqr = 93 - 78 = 15

the final has the greatest iqr

6.   b - there is a high data value that causes the data set to be asymmetrical for the males: the data for males are high and asymmetrical .   there is an outlier for the males that skews the data

5.   the   iqr is a better measure of spread for the movies and basketball games.   since the basketball game has an outlier, we do not want to use standard deviation for measurement.  

3.   the exam median is much higher than the class median.   the median line is farther to the right on the exams

2.   there is no way to tell what the means are from the box and whisker plots.
