2x - 10 = 4x - 8
-10 = 2x - 8
-2 = 2x
-1 = x
Answer:
2801 boxes
Step-by-step explanation:
You have 1 red box
You have 7 blue boxes, so far 8 boxes
There are 49 total black boxes (7*7), making 57 total boxes
There are 49*7 = 343 yellow boxes, making 400 boxes
There are 343*7 = 2401 gold boxes, making for a total of 2801 boxes.
Step-by-step explanation:
Look for keywords
when you see "per" that means theres a rate (something happens every unit of time)
To write a rate you divide whatever happens by whatever unit of time youre useing
In this example our rate is 15$ <em>per</em> hour which can be written as:
15$/1 hour (but we usually dont write it if theres a 1)
You can think of this as a regular fraction
Here the hour will cancel and youre left with $
To find the area of the circle use the A = πr²
r (or radius) = 1.5
Plug in 1.5 for r
A = π(1.5)²
Square 1.5
A = π(2.25)
A = 2.25π yd² is your answer
