5x + 6 = 21

Nick has 30 coins in his pocket. Some coins are nickels. Some are dimes. The total value of all of the coins in his pocket is $1
HACTEHA [7]
X + y= 30
.05x + .10y= 1.65

n + d = 30
5n + 10d = 165

-5n - 5d = -150
5n + 10d = 165

5d = 15

d = 3 dimes

n + 3 = 30

n= 27 nickels

How do you find the lateral area of the prism
Lina20 [59]
Hi there!

The lateral area is the area of the figures connecting the bases. We have rectangles here. We'll need to find the area of each figure and add them together to find the lateral area.

WORK:
(2.8 x 12) + (8.1 x 12) + 2(4 x 12)
33.6 + 97.2 + 96
LA = 226.8 units^2

Hope this helps!! :)
If there's anything else that I can help you with, please let me know!
