Answer:
equation : 2x + 4 = 3x - 5
X = 9
BC = 22
Answer:
y=5x
Step-by-step explanation:
Because it has the same slope, both equations must have 5x as their slope. The 2 equations are not going to have the same y intercept, so the +3 can be ignored and replaced with b. You want to plug in (1,5) into you new equation of y=5x+b, to get 5=5(1)+b. Multiply 5 by 1 to get 5, and then subtract 5 from both sides, which gives you 0=b. This means that the y intercept is the origin, so your new equation is y=5x
Answer:
1 and 1/16 gallons
Step-by-step explanation:
Answer: The three numbers are 10, 11, and 12.
10+11+12 = 33
=========================================================
Work Shown:
- x = smallest number
- x+1 = middle number
- x+2 = largest number
Each is a positive whole number
Add them up and set the result equal to 33. Solve for x.
(x) + (x+1) + (x+2) = 33
3x+3 = 33
3x+3-3 = 33-3 .... subtract 3 from both sides
3x = 30
3x/3 = 30/3 ..... divide both sides by 3
x = 10
x+1 = 10+1 = 11
x+2 = 10+2 = 12
Note how 10+11+12 = 33 to help confirm our answer.
