Hi there!
Let's start by replacing "a number" by the letter "x" so that we can do an equation and isolate "x" to find your answer :
(x - ) + = -7
subtract on each side of the equation
x - = -8.25
add on each side of the equation
x = -7.5
-7.5 - 3/4 = -8.25
-8.25 + 5/4 = <u>-7</u>
So your answer is : Three-fourths was subtracted from -7.5, and then 5/4 was added to the result. The sum was -7.
There you go! I really hope this helped, if there's anything just let me know! :)
Answer:
1/64
Step-by-step explanation:
To get from a₄ to a₉, we multiply a₄ by r⁵ (since 9 - 4 = 5). We know a₄ and r = 1/2 so the answer is 1/2 * (1/2)⁵ = 1/64.

Answer:
Approximately 50.8 miles per hour.
Step-by-step explanation:
We have been given that you travel again in your trusty car with the 25 inch wheels. The nifty gadget shows that right now they turn 41000 times per hour.
The distance covered by wheel in one turn would be equal to circumference of circle with diameter of 25 inches.
Distance covered by wheel in 41,000 turns would be 41,000 times :
We know that 1 miles is equal to 63360 inches.
To convert 3220132.4699 inches to miles we will divide 3220132.4699 by 63360 as:
Therefore, you are travelling at a speed of approximately 50.8 miles per hour.
