First, divide the total cost by the unit cost:
<span>(2y^2 + 6) / (y^2 - 1) </span>
<span>Then, if y = 3, just plug in and compute. </span>
<span>I know you can do that!

The minimum amount Jorge will have in savings for them to have $163 together is $110.34.
j = 2x + 1
= 2(54.67) + 1
= 109.34 + 1
= $110.34
So,
j + x - 2 = 163
110.34 + 54.67 - 2 = 163
165.01 - 2 = 163.01
Approximately,
163
Therefore, the minimum amount Jorge will have in savings for them to have $163 together is $110.34
Answer: 30 in.
Step-by-step explanation:
If it's an equilateral triangle, all sides are the same length. Therefore
3x + 15 = 7x - 5
x = 5
After figuring out x = 5, replace the x with five and solve the equation.
3(5) + 15 = 30
7(5) - 5 = 30
Now that we know the length of two sides, we can state that the third side-length <u>also</u> equals 30 inches because it is an equilateral triangle, meaning all sides are congruent/ the same.
Answer:
Length = 34 and Width = 30
Step-by-step explanation:
This is a simple system of equation that is mainly solved using substitution, so keep in mind the following key points:
- Rectangle's Perimeter is 128 ft.
- "the garden is 4 feet longer than it is wide," this simply means that the Length is 4 feet longer than the Width: which algebraically translates to
- Perimeter formula for Rectangle is
First, we find the Width by plugging the given values in the formula:
All we did here was substituting 4 + W for L to find the Width.
Now, to find the Length we plug in the value of W and solve for L:
Tip: always sketch a rough geometrical diagram of word problems, it helps. (Refer to the diagram attached)
