I will have "x" represent the unknown number, or you could use a "?", doesn't matter.
[8 is less than or equal to (≤) the quotient (÷) of a number and -4, so the number is being divided by -4]
If you need to solve this, you need to isolate/get the variable "x" by itself in the inequality:
Multiply -4 on both sides to get rid of the fraction and get "x" by itself
When you multiply/divide by a negative number, you flip the sign (< >)
-32 ≥ x [-32 is greater than or equal to x, or x is less than or equal to -32]
1/4 hour = 4 1/4 miles
Change to improper fraction:
1/4 hour = 17/4 miles
Multiply by 4 on both sides:
1 hour = 17 miles
Answer: Ramon rides his bike at 17 miles/hour.
Answer:
11 pounds
Step-by-step explanation:
Let the weight of Rover is x pounds.
As Fifi weighs 12 pounds less than Rover, so,
The weight of Fifi = x-12...(i)
As Fido weighs 26 pounds more then Fifi, so,
The weight of Fido = (x-12)+26=x+14.
As the sum of their weights is 71, so,
x+(x-12)+(x+14)=71
x+x-12+x+14=71
3x+2=71
3x=71-2=69
x=69/3
x=23
From equation (i), the weight of Fifi = 23-12=11 pounds.
Hence, the weight of Fifi is 11 pounds.
