Answer:
26
hope this heps and pls mark brainliest :))
Step-by-step explanation:
2n=14 n being the “number” divide 2 on both sides and you’re left w n=14/2 or7
First question:
1. Set equations equal to each other so 5x-9=2x+6
2. Put x's on one side so that 3x=15
3. Divide by 3 so that x=15
4. Substitute 15 in for x so that y=2(15)+6
5. Solve for y so that y=36
6. Thus the equations intersect at (15,36)
Second question:
1. Since for lines y=mx+b, and m=slope=3 you only need to write an equation with slope 3
2. y=3x+b, b can be any number
Answer:
Step-by-step explanation:
Set up proportions. Make sure length and widths line up!
Then do butterfly method.
Solve for x.
