Answer: 0.3 hours or 18 minutes
Step-by-step explanation:
The answer is A. You can get that in by plugging in and checking or by substitution. In order to use substitution here, you would plug in 3x + 3 into y in the first equation. You would then distribute the 2 and solve for x, which would give you 0. Then you could plug that into either equation to find that y = 3.
Answer:
x = 59
Step-by-step explanation:
So first lets distribute;
29 + x - 24 = 64
Collect like terms;
5 + x = 64
Subtract 5 from both sides;
x = 59
Divide the numerator by the denominator
Answer:
x = 5, -1
Step-by-step explanation:
0 = 3x^2 - 12x - 15 or
3x^2 - 12x - 15 = 0
By solving for x, use the Quadratic Formula.
… x = 5 and/or -1
