Answer:
x = 4.5
Step-by-step explanation:
there's definitely other ways to solve this, but I used a proportion.

Then you can make this equation:
14x = 3.5 * 18
I solved for it and got 4.5 .
THey tried to push but the wall doesn't move. So Nobody did any work. Everybody's work done is 0.
Plotting the data to get the line of best fit, it is:
y<span> = 0.087</span>x<span> + 0.587
substitute x=2030-1980=50,
y = $4.94 is the price in 2030</span>
Answer:
X = 51
Y = 12
Step-by-step explanation:
2 numbers: (Larger) Number 1 is x and Number 2 is y
The equation is x + y = 63
New equation is:
Combine like variables:
Solve:
- 4y + 15 - 15 = 63 - 15
- 4y = 48
Divide 4 from each side:
To find x fill in the variables from the 'x =' equation:
- x = 3y + 15
- x = 3( 12) + 15
- <em><u>x = 51</u></em>
