When you multiply the same number with different exponents together, you add the exponents together.
3^2 + 3^x = 3^7
Adding the two together you have 3^(2 + x = 7)
Solve for x: 2 + x = 7
Subtract 2 from both sides:
x = 5
E(x) = 10x - 30
the y int is -30........that means her expenses for the week was $ 30
Distance hour hand travel in 5 hours is 20.94 inches.

What is a diameter?</h3>
- A diameter of a circle is any straight line segment that passes through the center of the circle and has endpoints on the circle in geometry.
- It is also known as the circle's longest chord.
- Both definitions apply to the diameter of a sphere.
To find the distance hour hand travel in 5 hours:
- Let's say the hour hand completed one full round around the clock.
- If this was the case, it would have been 2×8 inches around.
- We know that the hour hand only traveled 5 hours around the clock rather than 12, thus our formula is 2×8×( 5/12 ).
- Distance hour hand travel is 20.94 inches.
Therefore, the distance hour hand travel in 5 hours is 20.94 inches.
