The answer is 1 and 4. hope this is helpful
Answer: it would be 12.
Step-by-step explanation:
2x^2 + 5x - 12 = 0
2x^2 + 8x - 3x - 12 = 0
2x(x + 4) - 3(x + 4) = 0
(2x - 3)(x + 4) = 0
2x - 3 = 0 or x + 4 = 0, so:-
solution is 3/2, -4.
-2 1/2 ÷ 6
= -(5/2) ÷ 6/1
= -(5/2) × 1/6
=-(5/12)
Answer: It will take Damon 6 weeks to save the money he needs to buy the snowboard
Step-by-step explanation:
First, let's see what the problem is giving us:
-The variable X will represent the number of weeks it will take Damon to save the money he needs.
- Damon has $40
- Damon is going to safe $20 weekly
- The snowboard costs $160
Therefor:
Our equation will be: $40 + $20X = $160
Step 1
We need to isolate the variable by subtracting in both sides of the equation 40 in order to maintain the equality.
40 - 40 + 20X = 160 - 40
This will let us with 20X = 120
Step 2
We have to isolate the variable again, but this time (because the variable is being multiplied by 20) we have to divide on both sides of the equation.
20X/20 = 120/20
Therefore: X=6
