Alright my friend so 30% of 50 will be 15
A) y = 2x -4
B) x + 2y = 12
A) -2x + y = -4 then multiplying Equation B by 2
B) 2x + 4y = 24
Adding the equations
5y = 20
y = 4
x = 4
Okay, that was solved by elimination.
If these equations were graphed, they would be two lines that would meet at the point (4, 4)
Answer:
whats the original temperature it cut off, c ant answer this without seeing that
but just keep subtracting 3 from it per hour

Answer: r=8
Step-by-step explanation:
Please give brainliest
Let the measure of one peice be x
then, the other peice must measure 5x
measure of 1st peice + measure of 2nd peice = total measure of the board
5x + x = 72
6x = 72
x = 12
So, the 1st peice measures x = 12cm
and the other measures 5x = 5 (12) = 60cm.
