If we say A = ream of paper and B = cost of ink than we can set-up an expression to calculate when A is equal to a number what the number of B will be.
Maximim of 270$ so anything we buy must be equal to this.
Ream of paper cost 6$ each so 6A represents the number of reams bought since we said A is number of reams of paper.
Ink Cartridges are 18$ each so 18B would represent this based on B = to cost of ink.
Now setting up our equation
6A + 18B = 270
When A = 1
B = 14.67 Ink Cartridges
When A = 1 Ream ofpaper
Answer:
135
Step-by-step explanation:
I think you mean the LCM instead of LMC. LCM stands for Least Common Multiple. Anyway, some of the multiples of 27 are 27, 54, 81, 108, and 135. Some multiples for 45 are 45, 90, 135. We can see here that 27 and 45 share the mutiple of 135 which is the first number they have in common.
Ethans is the correct one
Answer:
C.
Step-by-step explanation:
-3 7/8 rounds down to -4
4.63 rounds up to 5
-4 x 6 + 5
-24 + 5
-19
her answer (-19.14) also rounds to -19
So yes, it is reasonable and the correct response is C.
X² = 1/4 ⇒√⇒ x₁ = 1/2, x₂ = -1/2
