Answer:

Step-by-step explanation:
Given the information, create the following augmented matrix:
The first order was for 1 tray of club sandwiches, at a cost of $9. The second-order, which cost $69, was for 5 trays of club sandwiches and 4 trays of vegetarian sandwiches.

Into an augmented matrix:

Solve.
Let x be the cost of a tray of club sandwiches.
Let y be the cost of a tray of vegetarian sandwiches.
You have to plug in 2 for a and 6 for b.
(2)^2 + 4(2) + 7(6) 4 + 8 + 42 54
————————— = —————- = ——
5 - (2)^3 5 - 8 -3
The answer is -18.
we are asked to expand the logarithmic expression log base b square root of 57/74. In this case, the terms can be expressed as log 57/74 over log b. The expanded form is expressed as -0.1134 / log b. This can be also expressed as (log 57 - log 74)/ log b.
Answer:
42:49
Step-by-step explanation:
6x + 7x = 91
13x = 91
x = 7
6 x 7 = 42
7 x 7 = 49
then 42:49
