Answer:
I would change 2x+4y=24 into x=12–2y
To do that, divide both sides by 2 and then subtract 2y on each side.
After that, substitute for x. 3x+2y=19 would become 3(12–2y)+2y=19.
Then solve.
3(12–2y)+2y=19
36–6y+2y=19
-4y+36=19
-4y=-17
y=4.25
Then, substitute y in either equation.
Either this:
3x+2y=19
3x+2(4.25)=19
3x+8.5=19
3x=10.5
x=3.5
Or:
2x+4y=24
2x+4(4.25)=24
2x+17=24
2x=7
x=3.5
Or you could solve it in the equation you created in the beginning:
x=12–2y
x=12–2(4.25)
x=12–8.5
x=3.5
The coordinates where the lines intercept are (3.5, 4.25).
Sorry for the long answer!
Answer:
This is what internet says. Maybe this helps.
It would be: 0.25 = 25/100 = 1/4
so, your answer is 1/4
Formula: total = principal x (1 + (interest rate x loan time))
total = 1000 x (1 + (0.055 x 2))
total = 1000 x (1 + 0.11)
total = 1000 x 1.11
total = $1110
To solve for x, we need to get it on one side by itself, and then to make sure we are left with ONLY x, no coefficients or anything.
-2x -3 > 97.
Add 3 to both sides.
-2x > 100.
Divide both sides by -2 (remember to flip the inequality when dealing with negatives).
x < -50
I hope this helps!
