Answer:
1/2
Step-by-step explanation:
2x - 5y
2(2/3) - 5(1/4)
(2/1 x 2/3) - (5/1 x 1/4)
(4/3) - (5/4)
(4/3 x 4/4) - (5/4 x 3/3)
16/12 - 15/12
1/12
Answer:
Step-by-step explanation:
From the given information:
Let assume that the invested amount in the investment paying 8% interest is a
Now, since the total amount invested = $3000.
Then, the amount invested in the investment that will be paying 10% interest can be represented as:
= $(3000-a)
Income earned on $a that is being invested in 8% interest = $a × 8/100 = $0.08a
Income earned from $(3000-a) in the 10% investment is:
= $(3000-a)× 10/100
= $(300 - 0.1a)
Since total income of the two investment = $290;
Then;
0.08a + (300 - 0.1a) = 290
0.08a + 300 - 0.1a = 20-
300 - 0.02a = 290
-0.02a = -10
a = -10/-0.02
x = 500
Thus;
the amount invested in an investment paying 8% interest = $500
the amount invested in an investment paying 10% interest = $(3000 - 500) = $2500

Answer: 6x + 8y =1,245
Step-by-step explanation:
Hi, to answer this question we have to write an equation for each person:
Jack = The total cost (650) must be equal to the product of the number of shirts he bought (2) and the price per shirt (x); plus the product of the number of pair of jeans he bought (5) and the price per jean (y).
2 x+ 5 y=650
Dylan = The total cost (595) must be equal to the product of the number of shirts he bought (4) and the price per shirt (x); plus the product of the number of pair of jeans he bought (3) and the price per jean (y).
4x+3y = 595
Vertical addition:
2 x+ 5 y=650
+
4x+3y = 595
_________
6x + 8y =1,245
Answer: x = 27, y = 23
Explanation:
x = chickens
y = horses
║ x + y = 50
║ 2x + 4y = 146
║ 2x + 2y = 100
║ 2x + 4y = 146
(2x + 4y = 146) - (2x + 2y = 100)
2y = 46
y = 23 <span> <<<<<<<< We found y ¯\_(ツ)_/¯
Sub y = 23 into </span> x + y = 50
x+ 23 = 50
x = 50 - 23
x = 27 <<<<<<<< We found x ¯\_(ツ)_/¯
