Answer:
Step-by-step explanation:
The coefficients of x and y in the first equation will be the 2 x 2 matrix first row and the coefficients of x and y in the second equation will be the second row:
When you take the inverse of that 2 x 2 matrix and multiply it with the right side matrix (-16 -48), you can find the solution for x and y.
The number 42 and then decrease it or subtract twice what ever he has in savings. 42-(2GS) GS is goarans savings. most of the time we would use a variable like x so it could be written as 42-(2x) depends on how the teacher wants it.
Answer: 150
Step-by-step explanation: Half of 300 is 150.
Answer:
6.29
Step-by-step explanation:
so you know that the unknown side which is 7x + 27 equals 71.
You can begin by subtracting 27 from 71 which will give you 44.
you then know that 44 = 7x
then you just have to do 44 divided by 7 to find x which isss...
