|2x + 1| < = 5
-5 < = 2x + 1 < = 5 ...subtract 1
-5 - 1 < = 2x + 1 - 1 < = 5 - 1
-6 < = 2x < = 4 ....divide by 2
-6/2 < = (2/2)x < = 4/2
-3 < = x < = 2
B. a number line with closed dots (because of the = sign) on -3 and 2 with shading in between
10a+35b=0; 21a-35b=217 ...associative property of addition
31a = 217 .............addition property of equality
a = 7 .....................division property of equality
2(7) +7b = 0 --------------substitution property of equality
14+7b = 0 -----------------mulplication property of equality
7b = -14 --------------subtraction property of equality
b = -2 ----------------simplify
12(6) 1/2(7) and 1(8) I think
Answer:
5
Step-by-step explanation:
it is the answer and i beleive
Answer:
PA+AR=PR
AR= PR- PA
AR= 8x+14-(7x-11)
AR= 8x+14-7x+11
AR= x+25
Now, if A is midpoint of PR, then
PA=AR
7x-11= x+25
6x=36
x=6
Put value of x in AR
AR= 6+25= 31
Hope this will help:)
