<h3>
Answer: 3x - 4y = 40</h3>
======================================
Work Shown:
y = (3/4)x - 10
4y = 3x - 40 .... multiply everything by 4 to clear out the fraction
4y+40 = 3x
40 = 3x-4y
3x-4y = 40
This is in the form Ax+By = C
A = 3, B = -4, C = 40
This is not the only solution possible since we can multiply both sides by some number to scale the equation.
Answer:
262
Step-by-step explanation:
If x is the first integer, then x+1 is the second, x+2 is the third, and so on. Meaning the 7th term in the list is x+6.
x + x + 6 = 518
2x = 512
x = 256
The first integer is 256, so the last integer is 262.
X equals to 48
The work is shown in the picture. I hope this helps.
Step-by-step explanation
b = 2h is given
2 b + h = 4 hours is given sub in the top equation
2 (2h) + h = 4
5h = 4
h = 4/5 hr or 48 minutes
