A= 5*6/2= 30/2= 15 cm^2
Answer:
33x-25
Step-by-step explanation:
2(3x-5)-3(6-4x)+(15x+3)
6x-10-18+12x+15x+3
21x+12x-10-18+3
=33x-25
Answer:

Step-by-step explanation:
The first term is 22. It looks like each term after that is the term before, plus a negative 3.
a-sub-one = 22
common difference = d= -3
Formula for
:
= 25 - 3n
Answer:
0.62kg
Step-by-step explanation:
Let
x = 40/kg coffee
y = 11/kg coffee
two equations can be derived from the question
x + y = 12 equation 1
40x + 11y = 114 (9.5 x 12) equation 2
multiply equation 1 by 11
11x + 11y = 132 equation 3
subtract eqn 3 from eqn 2
29x = 18
divide both sides of the equation by 29
x = 0.62kg
