Answer:
a) -3/13
b) -1/8
Step-by-step explanation:
a) - (21 / 7) / (91 / 7) = 3/13
b) (32 / 32 ) / - (256 / 32) = -1/8
Answer:
Find the common like terns in each expression!
Step-by-step explanation:
For example A:
+3y +2x -2y +5z
+3y -2y = 1y or y
Then sort by the greatest values:
5z+2x+1y
Not all of the student body would have responded therefore her conclusion was incorrect, could be changed to be right by saying 90% of people who responded to a survey said the school colours should be changed.
-5 +25-10m ≥ 60
20-10m ≥60
-10m ≥40
m ≤ -4 note flip equality sign because diving by a negative number
5 (4n+5)-4 ≤ 101
20n +25-4 ≤101
20 n +21 ≤ 101
20n ≤ 80
n ≤ 4
3(4-5p) -4 ≥ -67
12 -15p-4 ≥ -67
8 -15p ≥ -67
-15p ≥ -75
p ≤ 15 also flipped sign
-3(5m+2). < 54
-15m -6 &It 54
-15 m &Lt 60
m < -4
( I don’t know what sign < means I am assuming less than ? Just put the appropriate sign )
3x -4 (-5x+3) ≥ 57
3x +20x -12 ≥ 57
23x -12 ≥ 57
23x ≥ 69
x ≥ 3
