You start with 80 and ADD 10 each week
----> 80 + 10x
Your brother starts with 275 and SUBTRACTS 15 each week
---> 275 - 15x
Set expressions equal to find out when you have same amount as your brother.
80 +10x = 275 -15x
Add 15x to both sides
80 +25x = 275
Subtract 80 from both sides
25x = 195
Divide by 25
x = 7.8 (Round up to 8)
This means in 8 weeks you will have caught up and if fact have more money than your brother.
Since you save 10 per week, in 8 weeks the Total saved = 10*8 = 80
Answer:
48x + 216 square inches.
Step-by-step explanation:
Area is length X width.
Area is (4x + 18)(12).
in 4x + 18, 18 comes from adding the three 6 in.
We have no values for "x", so expand the equation and simplify.
(4x + 18)(12)
= 48x + 216
Answer: ![\sqrt{66}](https://tex.z-dn.net/?f=%5Csqrt%7B66%7D)
Step-by-step explanation:
The Pythagorean Theorem says that a^2 + b^2 = c^2 where a and b are the two legs.
In this care leg 1 is 4 and leg two is the square root of 50. So we will square them to find c which is the hypotenuse.
4^2 +
= C^2
16 + 50 = c^2
66 = c^2
c =

here eight zeros after decimal point
7.2 × 10-9 = 0. 0000000072
In order to solve this problem, we must convert 1/2 and 5/7 into decimal form or convert 0.55 into fraction form. I'll convert 1/2 and 5/7 into decimal form because it is easier.
1/2 = 0.5
5/7 = <span>0.71
and 0.55 is given.
Now we have 0.5, 0.55, and 0.71, and it is easier to see the order of size.
0.5, 0.55, 0.71 is the order from least to greatest, but we must put 0.5 and 0.71 back into their original forms.
Therefore, the answer is 1/2, 0.55, 5/7</span>
