Answer:
221 minutes
Step-by-step explanation:
52 divided by 20 would be 2.6 then you take the 85 and mulitpy it by 2.6 because 52 is 2.6 times more than 20. so 85 times 2.6 would be 221 minutes.
Answer:
Step-by-step explanation:
Let the number be x.
four times the number:
4x
If the exprression is increased by 1, it will become:
4x+1
If the value is between -7 and 13, the value of x will be within the range [-6, 12]
Equating the resulting expression to each end point.
At end point of -6
4x+1 = -6
4x = -6-1
4x = -7
x = -7/4
At the end point of 12:
4x+1 = 12
4x = 12-1
4x = 11
x = 11/4
Hence all the numbers will be within the range [-7/4, 11/4] or -7/4≤x≤11/4
The answer is D. x < 5.
9x+27 <72
9x <72-27
9x <45
x <45÷9
x <5
