Step-by-step explanation:
<u>Step 1: Define</u>
3x - 4y = 7
<u>Step 2: Solve for </u><em><u>x</u></em>
- Add 4y to both sides: 3x = 4y + 7
- Divide 3 on both sides: x = (4y + 7)/3
Answer:
The are 125:9
Step-by-step explanation:
When we know the scale factor
The lengths are related by the scale factor
The areas are related by the scale factor squared
The volumes are related by the scale factor cubed
Since the scale factor is 5:3
Cube each side
5^3: 3^3
125:9
The are 125:9

Answer: 157 ft
Step-by-step explanation: To find the circumference of a circle, start with the formula for the circumference of a circle which is shown below.
Circumference = 2πr
Notice that the circle has a radius of 25 feet. So we can plug in 25 feet for <em>r</em> in the formula. So we have (2)(π)(25 ft) which is equal to 50π ft.
Remember that π is approximately equal to 22/7 or 3.14 so we can estimate the value of the circumference by plugging in 3.14 for π.
So we have (50)(3.14) which is equal to 157.
So the circumference of the circle is approximately equal to 157 ft.
Answer:
$16.5
Step-by-step explanation:
