Answer:
3 faces
A cylinder has 3 faces - 2 circle ones and a rectangle (if you take the top and bottom off a tin can then cut the cylinder part on the seam and flatten it out you would get a rectangle). It has 2 edges and no vertices (no corners).
Step-by-step explanation:
Eighteen divided by 2/3 equals D. 27
To solve for the equation -2x+5=4x-7, you first have to isolate the variable X on one side and bring the rest to the other side
-2x+5=4x-7
Add 2x on both sides
5=6x-7
Isolate X by adding 7 on both sides
12=6x
Solve for X by dividing by 6 on both sides
x=12/6
x=2
Answer:
Step-by-step explanation:
BASE + 3x = 22.85.....................equation 1
BASE + 10x = 40..........................equation 2
BASE = 40 - 10x
NOW SUBSTITUTE (40-10x) FOR BASE IN THE FIRST EQUATION
40 - 10x + 3x = 22.85
-7x = 22.85 - 40
-7x = -17.15
x = -17.15/-7
x = $2.45 IS THE PRICE FOR EACH POUND.
BASE + 10 x 2.45=40
BASE + 24.50=40
BASE = 40-24.50
BASE = 15.50 IS THE BASE PRICE FOR THE DELIVERY.
PROOF
15.50+3*2.45=22.85
15.50+7.35=22.85
22.85=22.85
6/4 it’s easy:) your welcome
