Answer:
y=10x
Step-by-step explanation:
1. The balloon is going up, so it won't be a negative number
2. It's going at a rate of 10 per second, and x represents seconds
Answer:
x + (2x-12) = 84
x = 32
Step-by-step explanation:
you can say (part 1) + (part 2) = 84
one part is x (a variable) and
other part is 12 less than twice the other: when it says "12 less" is " - 12" and twice of part one 2x, you can say (2x - 12)
(part 1) + (part 2) = 84
x + (2x-12) = 84
3x - 12 = 84
3x = 96
x = 32
(part 1) + (part 2) = 84
(32) + (2*32 - 12) = 84
(32) + (52) = 84
Answer:
The total cost of boring the 750 meters is $37,700.
Step-by-step explanation:
We know that the cost of the first meter is $250.
You want to keep on adding $50 each time you add a meter for example the cost of the second meter would be $300 because you add $250+50. Another way is that you can multiply so for the third meter it would be $350 as you $250+50(2).
In that way you can see a pattern forming and we want to subtract 1 variable when multiplying as you are already originally adding $50.
So now we want to form an equation to solve for the cost of 750 meters. The equation I would make is
250+50(750-1)
then you can solve to get 37700 that is shown below
250+50(750-1)
250+50(749)
250+37450
37700
That will be our answer!
The total cost of boring the 750 meters is $37,700.
Answer: The slope is 4x.
Step-by-step explanation: First, subtract 4y from both sides to get 16x-4y=1. Next, subtract 16x from both sides to get -4y=-16x+1. Finally, divide all terms by -4 to get y=4x-0.25. The slope is represented by 4x.
