N/4 < -1 — we can multiply both sides with 4, so we dont have to deal with fractions.
N < -4
So, our N goes left from -4 on a number line.
-10x<-100 — divide both sides by 10
-x < -10
x > 10
X is from 10 rightwards.
5x>20 — divide both sides by 5
x > 4
X is rightwards from 4.
Step-by-step explanation:
6x-12=x+3
6x-x=3+12
5x=15
x=15/5
x=3
Step-by-step explanation:
x = 2.5
(2.5 × 0.25 ) + 2= 0.625 +2
= 2.625
Answer:
2
Step-by-step explanation:
the rate of change is Rise/ Run
= Δy / Δx
= (y2 – y1) / (x2 – x1)
= (1 - (-1))/(-1 - (-2))
=2/1
=2
The expression that gives the number of Jackets that can be made from a fabric of 1634 yards will be found as follows:
let the number of jackets be x.
the total length of material required to make x jackets cannot exceed 1634 yards, it can be equal to or less than 1634. Thus, the expression will be given as follows:
amount required to make one jacket is 378,hence:
378x≤1634
x≤4.32275
approximating the above we get:
x≤4
