Answer:
<u>The price of oranges is US$ 2 per pound and the price of bananas is US$ 1 per pound.</u>
Step-by-step explanation:
1. Bananas and oranges bought by Nancy:
Oranges = 7 pounds
Bananas = 3 pounds
Cost = US$ 17
2. Bananas and oranges bought by Nancy's husband:
Oranges = 3 pounds or 3x
Bananas = 6 pounds or 6y
Cost = US$ 12
3x + 6y = 12 (Dividing by 3 at both sides of the equation)
x + 2y = 4
x = 4 - 2y
3. Total Purchases:
Oranges = 10 pounds or 10x
Bananas = 9 pounds or 9y
Cost = US$ 29
10x + 9y = 29
10 (4 - 2y) + 9y = 29 (Replacing x with 4 - 2y from 2nd purchase)
40 - 20y +9y = 29
-11y = 29 - 40
- 11y = - 11
y = 1 (Dividing by -11 at both sides)
<u>Pound of bananas = US$ 1</u>
10x + 9 (1) = 29 (Replacing y by 1 in the original formula)
10x + 9 = 29
10x = 20
x = 2 (Dividing by 10 at both sides)
<u>Pound of oranges = US$ 2</u>
Answer:
The answer I'm not too sure but I think you don't have to chear to know.
Step-by-step explanation:
We know that
<span>applying the Pythagorean theorem
(3959+2.9)</span>²=x²+3959²
x²=(3959+2.9)²-3959²
x²=3961.9²-3959²
x²=22970.61
x=√22970.61
x=151.56 mi
the answer is
x=151.56 mi
Answer:
.03
Step-by-step explanation:
-80%=-.8
54/50=108/100=1.08
1.08-.8-.25
1.08-1.05
0.03
Answer:
(3,0)
Step-by-step explanation:
So, if it is 3 away from the origin(0,0) it cannot be (3,3) or (3,6). (3,0)is the answer because it is the x-axis and and the dot is at 3. A great website is desmos. Use it for graphing. Good luck!
