Answer:
25 and 1/5 miles.
Step-by-step explanation:
If Hunter walks 1 and 2/5 miles a day, then we take that a multiply it by 18. Let's convert the mixed number into an improper fraction to make it easier.
1 2/5 = 7/5.
18*7/5 = 126/5 = 25 and 1/5 miles.
Hope this helps.
Answer:
Apple = $0.6
Banana = $0.75
Step-by-step explanation:
Let us represent Apple by A and Banana by B
For Joe,
5A + 4B = 6 (1)
For Dawn
3A + 6B = 6.3 (2)
To eliminate A, Multiply equation (1) by 3 and equation (2) by 5
15A + 12B = 18 (3)
15A + 30B = 31.5 (4)
subtracting equation (4) from (3)
15A - 15A +12B - 30B = 18 - 31.5
-18B = -13.5
divide through by -18
-18B/-18 = -13.5/-18
B = 0.75
substitute 0.75 in equation (1)
5A + 4B = 6
5A + 4(0.75) = 6
5A + 3 = 6
subtract 3 from both sides
5A + 3 - 3 = 6 - 3
5A = 3
divide through by 5
5A/5 = 3/5
A = 0.6

Answer:
=4x^2−20xy+25y^2
Step-by-step explanation:
(2x−5y)^2
=(2x+−5y)(2x+−5y)
=(2x)(2x)+(2x)(−5y)+(−5y)(2x)+(−5y)(−5y)
=4x^2−10xy−10xy+25y^2
=4x^2−20xy+25y^2
