Answer:
Step-by-step explanation:
Substitute y = x - 8 for y in 2x + 3y = 1:
2x + 3(x - 8) = 1
2x + 3x - 24 = 1
5x - 24 = 1
5x = 25
x = 5
Substitute 5 for x in y = x - 8 and 2x + 3y = 1
y = 5 - 8 --> y = -3
2(5) + 3y = 1 --> 10 + 3y = 1 --> 3y = -9 --> y = -3
x = 5 and y = -3
Answer:
t represents the number of hours.
Step-by-step explanation:
I could be wrong because there is no t in that equation, but the equation should be 9t=26. T would represent the time (in hours)g it would take to go 26 miles.
Hello from MrBillDoesMath!
Answer:
4x
Discussion:
(2x -y ) + (2x + y) = by the Associative property
(2x + 2x ) + ( -y + y ) =
4x
Thank you,

Answer: x² + 3x + 1
Step 1: Carry down the first number 1 as it is
Step 2: Multiply 1 by -3 (1 * -3 = -3) and write this -3 under the next number 6 and then add. 6 + (-3) = 3
Step 3: Multiply this 3 by -3 (3 * -3 = -9) and write this -9 under the next number 10 and then add.10 +[-9] = 1
Step 4: Multiply 1 by -3 (1 * -3 = -3) and write this -3 under the next number 3 and then add. -3 +[-3] = 0
