Step-by-step explanation:
7 = √49
8 = √64
So any positive integer between 50 to 63, both inclusive, have a square root between 7 and 8.
Answer:
0.4
Step-by-step explanation:
2/5 =0.4
The unit cost =0.4
First divide by 4 to get x^2=9. Then take the square root of both sides. x=3 and x = -3.
Answer:
z≥−3
Step-by-step explanation:
1 Subtract 88 from both sides.
5z≥−7−8
2 Simplify -7-8−7−8 to -15−15.
5z≥−15
3 Divide both sides by 55.
z≥− 15/5
4 Simplify 15/5 to 3
z≥−3
