I think the answer is D because all the other options have a decimal point e.g. $4.46, (I don't use pounds but I'm assuming it's something like 4 pound 46), 4 hours, 46 minutes. You simply cannot have 0.46 of a dog (unless you're very cruel.)
N.B. I only used 4.46 as an example, it's not the correct number.
Answer:
x=1/2, y=4
Step-by-step explanation:
Double both sides of the top equation:
4x+6y=26
Now subtract boths sides of the second one from the first one:
(4x+6y) - (4x-y) = 26 - (-2)
7y = 28
so y = 4
4x-y=-2 so 4x-4=-2
4x=2
x=1/2
Answer:
2 miles per hour
Step-by-step explanation:
She miles 1/2 mile every 15 minutes or 1/4 hours so
1/2*4=2 miles per hour
The answer to the question is 15x+30-64
To solve A = P(1 + rt) for r, first isolate (1 +rt) by dividing both sides of this equation by P:
A/P = 1 + rt.
Next, isolate rt by subtracting 1 from both sides:
A/P - 1 = rt
Finally, divide both sides by t:
A/P - 1
----------- = r
t
This could be written in other formats, such as:
A - P
-------- = r
Pt
