Answer:
x=1
Step-by-step explanation:
First find a common denominator between 7 and 4 which is 28, Multiply both equations by 28 eliminating the denominators so now you have theses two equations: 4(2x + 12) = 7(3x + 5) distribute these equations to get:
8x + 48 = 21x +35 now you want to get the x's on one side so 8-21 = -13 which as an equation so far would be -13x + 48 = 35 now do 35-48 = -13 so you can have 13x alone on one side. Your final equation now before you solve is
-13x = -13 the divide -13 by -13 to get 1.

Answer:
Medium
Step-by-step explanation:
The computation is shown below:
The cost for the small and medium bag is shown below:
As we know that
1kg = 1000g
So 3kg = 3000g
Now for small bags
= 0.95 ÷ 250 × 3000
= £11.40
For medium bags
= £1.80 ÷ 500 × 3000
= £10.80
So here the medium bag would represent the better value
Answer: 4
Step-by-step explanation:
We know that a plane is 2 dimensional surface that extends infinitely far.
The number of points required to define a plane = 3
Here , we have 4 points A, B, C, and D.
So, the number of possible combinations of 3 points to make a plane from 4 points = 
[ 
]
Hence, the greatest number of planes determined using any three of the points A, B, C, and D if no three points are collinear = 4.
