Answer:
-6 ≥ r
Step-by-step explanation:
–5 ≥ 5 (r+5)
Divide each side by 5
–5/5 ≥ 5/5 (r+5)
–1 ≥ (r+5)
Subtract 5 from each side
-1-5 ≥ r+5-5
-6 ≥ r
Answer:
The answer should be 120.
Step-by-step explanation:
30% of 400 = 120 cats
It is a whole number and integer.
20 cents
4 people are sharing the money: Maya + 3
3(0.25) + 0.5 = 0.80
0.80 / 4 = 0.20
Let the width be x, the length is then 3x-10
Area of a rectangle is length times width: x(3x-10)=77 => 3x^2-10x-77=0
Factor this quadratic equation: (x-7)(3x+11)=0 =.x=7 or x=-11/3
width cannot be negative, so the only answer is x=7
width is 7m, length is 11m
