Hey there! I'm happy to help!
Let's set this up as a proportion (2 equal ratios).
If you multiply the diagonal numbers, their products will be equal. (412×g=103×184). This is called cross multiplying. Now we can solve for g.
412g=18952
Divide both sides by 412.
g=46
Therefore, the boat will need 46 gallons of gasoline to go 184 miles.
Have a wonderful day! :D
To make x^2 + 2x a perfect square we need to add the term { 2 / (2*1) }^2
which equals 1.
Add 1 to both sides: x^2 + 2x = 8
add 1 to both sides: x^2 + 2x + 1 = 8 + 1 (x + 1)^2 = 9
Take square root on both sides: x + 1 = +/- 3 x = +3 - 1 or x = -3 - 1 x = 2 or x = -4

<u>Interest paid during the 3 year</u>
- Sum of Interest paid during the 3 years
Answer:
x=2
TU:4(2)-1=7
UB: 3
TB: 10
Step-by-step explanation:
4x-1+2x-1=5x
6x-2=5x
6x=5x+2
subtract 5x from both sides
x=2
TU: (4x-1)
4(2)-1
8-1
7
TU:4(2)-1=7
UB: (2x-1)
2(2)-1
4-1
3
UB: 3
TB: 5(2)
TB: 10
