Answer:
Equation: 7x - 23 = 25 + x
Solution: x = 8
Step-by-step explanation:
7x - 23 = 25 + x
1. Subtract 25 from both sides:
7x - 23 - 25 = 25 - 25 + x
7x - 48 = x
2. Subtract 7x from both sides to get x on one side:
7x - 7x - 48 = x - 7x
- 48 = -6x
3. Divide both sides by -6 to get x by itself:
8 = x
8 is the solution
Answer:
1.55%
Step-by-step explanation:
Fill in the values and solve for the rate using the future value formula.
FV = P(1 +r/n)^(nt)
4720 = 4300(1 +r/12)^(12·6)
(4720/4300)^(1/72) = 1 +r/12
r = 12(4720/4300)^(1/72) -1) ≈ 0.015542
The annual interest rate is about 1.55%.

Answer:
2 units^2
Step-by-step explanation:
The area of a triangle is given by the formula
A = 1/2 bh where b is the length of the base and h is the height
b = 2 and h =2
A = 1/2 (2) * (2)
A = 1/2*4
A = 2 units^2
The most expensive would be one foot wide and forty eight feet long (or vice versa) and the least expensive would be eight foot wide and six foot long (or vice versa).
