If q = -10
Then:
q^2 = qxq
q^2 = (-10)(-10)
q^2 = 100
The answer is: x<12
Steps by steps
5(x+5)<85
Divide each term by 5 and simplify.
5(x+5)÷5<85÷5
Reduce the expression by cancelling the common factors.
x+5<85÷5
Divide 85 by 5.
x+5<17
Move all terms NOT containing "x" to the right side of the inequality.
Subtract 5 from both sides of the inequality.
x<-5+17
Add -5 and 17.
=x<12
For -5x+3y+2z=19 the answer is -19/3
12/60 students chose science fiction
Approximately x/150 students prefer sf
60x = 1800
x = 30
30/150 students are assumed to prefer sf
30/150 = x/100
150x = 3000
x = 20
20/100 students are likely to prefer sf
Mr. Rodriguez made a reasonable estimate for the approximate percentage of students that prefer science fiction, because if 12/60 is equivalent to 30/150 which refers to the number of students who can be assumed to prefer science Fiction out of the whole school. Considering we need to identify what 30/150 as a percentage is, we can reduce it down to 1/5 to make I easier, then divide 1 by 5 to get .2
.2 as a percentage is 20%, so his inference was indeed reasonable.
