139.50/55.8=t
t=2.5 yrs simple interest
Answer:
46 ≥ 2m + 4
m ≥ 21
Step-by-step explanation:
At least is ≥
Karen's age = 46 years old
Mary's age = m years old
Karen is at least 4 years more than twice mary's age (m).
46 ≥ 2m + 4
46 - 4 ≥ 2m
42 ≥ 2m
m ≥ 42/2
m ≥ 21
Answer:
B) w=3z+2
Step-by-step explanation:
The slope is 3 given the graph and the y-intercept is 2 since when x=0, y=2. So B must be right.
Answer:
Step-by-step explanation:
Remark
I'm not sure I know what you intend for the slope. I will take it as 12/3 = 4
If that is the case then what you have so far is
Solution
y = 4x + b
The given point determines b
<em>Givens</em>
x = 3
y = 2
<em>Given point</em>
2 = 4*3 + b
2 = 12 + b
b = 2 - 12
b = -10
The equation is y = 4x - 10
5. Because 5 x 5 = 25. 25 x 5 = 125. or 5^3 is 125, which could be proved with a calculator. Hope this helps.
