Answer:
Carrots cost $ 1.75 a pound which is more than potatoes cost.
Step-by-step explanation:
Let,
Carrots cost $ x per pound and potatoes cost $ y per pound.
Buying 2 pounds of carrots and 3 pounds of potatoes will cost her
$ 
and
Buying 4 pounds of carrots and 4 pounds of potatoes will cost her
$ 
According to the question,
-----(1)
-----(2)
multiplying (1) by 2 we get,
-----(3)
Deducting (2) from (3) we get,
⇒ 
------------------(4)
Putting value of y in (1) we get,
⇒ 
------------(5)
Answer:
1/676
Step-by-step explanation:
There are 52 cards
P(Ace of spades) = Number of aces of spades / total = 1/ 52
The replace the card
There are 52 cards
There are 4 kings
P(king) = number of kings / total = 4/52 = 1/13
P( ace of spades , replace, any king) = 1/52 * 1/13 = 1 /676
Answer:
The coordinates of the midpoint of the segment is (1,3.5)
Step-by-step explanation:
In this question, we are concerned with finding the coordinates of the mid point of the line that joins segment lb
To do this, we shall be using the midpoint formula;
(x,y) = (x1 + x2)/2, (y1 + y2)/2
Where (x1,y1) = (8,5)
(x2,y2) = (-6,2)
Thus;
(x, y) = (8 + (-6))/2, (5 + 2)/2
(x ,y) = (2/2), (7/2)
(x,y) = (1,3.5)
8x + 3y = 20.50
-
4x+5y=22.50
=
4x-2y=-2, so you have to divide each number by 2, then
2x-y=-1, so
-y=-1-2x /-1, y=1+2x, then replace it with one original equation like the first one for instance:
8x+3(1+2x)=20.50, then
8x+3+6x=20.50, then
14x=20.50-3
14x=17.5
x=1.25, then solve y:\
y=1+2*(1.25)
y=1+2.5
y=3.5,
So answer is x=1.25, and y=3.5
