If the data set represents the number of rings each person is wearing, being: 0,2,4,0,2,3,2,8,6, the interquartile range of the data is 2. Being, 4 as the Q1, 3 as the Q2 or median, and 6 as the Q3. Where the formula of getting the interquartile range is IQR= Q1-Q2.
Inequality hope this helps :)
Bring like terms together
(REMEMBER CHANGE THE SIGN WHEN MOVING ACROSS THE EQUAL SIGN i.e. - becomes + and + becomes -)
4x - 2x = 7 - 3
2x = 4
divide both sides by 2
x = 2
The answer for 5. is y+5. In an isosceles triangle, 2 of the sides are congruent. If the base is 4y+2, the other 2 sides must equal to 2y+10. Since both sides are congruent the only answer would be y+5.
Hope that helped :))))
