I need help with this

goldenfox [79]

for a triangular prism, its volume will simply be <u>area of its base</u> times its length.

the are of the base for this one is simply any of those triangular bases. Now, let's notice, the right-triangle has a base of 9 and a height o 9, notice the tickmarks, whilst the prism also has a length of 13.

$\bf \stackrel{\textit{area of the triangle}}{\cfrac{1}{2}(9)(9)}~~\cdot~~ \stackrel{\textit{length}}{(13)}\implies 9\cdot 13\implies 117$

Mrs.E bought 3 drinks and 5 sandwiches for $25.05 and Mr.E bought 4 drinks and 2 sandwiches for $13.80. How much does each drink

MAVERICK [17]

Answer:

$1.35

Step-by-step explanation:

Set up a system of equations, where d represents the price of one drink and s represents the price of one sandwich:

3d + 5s = 25.05

4d + 2s = 13.80

We can solve this by elimination by multiplying the top equation by -2 and multiplying the bottom equation by 5.

-6d - 10s = -50.1

20d + 10s = 69

Add them together:

14d = 18.9

d = 1.35

Please help me. I know 3^x but I’m confused how to figure out the other answers

jekas [21]

Well i can help you with one more which is 9x*3x/9x Since 9*3=27 so 9x*3x=27x Then the 9x is still there ending up with 27x/9x which is your starting fraction :)
