Answer:
r ≤ -1
Step-by-step explanation:
Given in the question
<h3>
3r+2(12r+7) ≤ 5r-8</h3><h3>
It can be solve by Simplifying and Reordering the terms</h3>
3r + 2(12r) + 2(7) ≤ 5r - 8
3r + 24r + 14 ≤ 5r - 8
27r + 14 ≤ 5r - 8
27r - 5r +14 + 8 ≤ 0
22r + 22 ≤ 0
22r ≤ -22
Move term containing r to the left, all term to the right.
r ≤ -22/22
simplifying
r ≤ -1
all negative integers which are smaller than or equal to -1
Answer:
(20 - 24)/6
Step-by-step explanation:
We have the algebraic expression
6(x + 4)= 20
We expand the brackets
6x + 24 = 20
Collect like terms
6x = 20 - 24
x = (20 - 24)/6
A correct solution to the expression is
(20 - 24)/6
Answer:
