Answer:
x = -40
Step-by-step explanation:
First we distribute
5x + 35 + 2 = 4x - 4 + 1
Collect like terms
5x + 37 = 4x - 3
Subtract 37 from both sides
5x = 4x - 40
Subtract 4x from both sides
1x = -40 OR x = -40
Suppose that this person drives at r mph going to the mountains, and gets there in 12 hours. Returning, this person drives at (r+20) mph and gets home in 8 hours. We don't know the distance yet, but can solve for the initial speed, r, by setting
d = 12r = (r+20)(8). Solving for r, r=40 mph (going) and (40+20)mph = 60 mph (returning. Since d=12 r, d = (12 hrs)(40 mph) = 480 miles (answer).
Answer:
So in other words, each week he works, he gets an additional $10, to add to his collection of really $75.
Step-by-step explanation:
so, he has $85 in savings, and that he has the opportunity to gain allowance by the following function of 10(x-1).
total funds(x) = 85 + 10(x-1)
T(x) = 85 + 10x - 10
T(x) = 10x + 75
Okay. First thngs first, let's divide each of them. 2.6/1.3 is 2. Now in terms of exponents, we would just simply subtract the powers, because we are doing division. 9 - 2 is 7. The value of the expression is 2 * 10^7. Even writing the problem out in number form (2,600,000,000/130), you can still see the answer to the problem as 20 million. The answer is B.
