This is only one equation. It is therefore not a system and you can not solve for two different variables y and z unless you have another equation to solve with. It.
42 less than x is -50 would be written as x - 42 = -50
Answer:
51.1 ≈ r
Step-by-step explanation:
"A bicycle wheel travels 321 in for each revolution"- means that 321 is the circumference of the wheel that is a circle.
C = 2· π· r
What is the radius of the wheel ?
321 = 2· π· r, divide both sides of the equation by 2 π
(321/2·π) = r , use calculator, solve and round the answer
51.1 ≈ r
Answer:
125
Step-by-step explanation:
To find the common ratio, take the second term and divide by the first term
1000/2000 = 1/2
We multiply each term by 1/2
2000, 1000, 500
To find the next term 500*1/2 = 500/2 = 250
To find the 5th term
250*1/2 = 125
