Answer:
Step-by-step explanation:
5 * 5 * 5 * 5
= 625
(63x³+45x²)+(7x+5)
108x²+7x+5 is your answer
We already know that C = 45. All we really need to do is simplify the equation and then solve for x.
45 = x + 0.06x + 0.08x + 0.1x
45 = (1 + 0.06 + 0.08 + 0.1)x
45 = 1.24x
x = 36.2903, which rounds to $36.29 for the haircut.
Answer:In 8 years the tree will have the same height.
Step-by-step explanation:
Step 1:
Let x = the number of years when the two trees will be the same height.
For the 2ft tree, you can express its height in x years as:
2+1(x)
And for the 6ft. tree...
6+0.5(x)
Step 2:
2+x = 6+0.5x Subtract 0.5x from both sides.
2+0.5x = 6 Now subtract 2 from both sides.
0.5x = 4 Finally, divide both sides by 0.5
x = 8
