Answer:
He can buy 3 plants
Step-by-step explanation:
$27 is the total amount of money he can spend, if each plant costs $9 the equation would be like this:
9x = 27
Divide 27 by 9 because division is the opposite operation to multiplication
x = 3
In this case there would be no solution bc the x's are the same
The price of one hat is $2 and price of one pair of mittens is $5.
Step-by-step explanation:
Let,
Price of one hat = x
Price of one pair of mittens = y
According to given statement;
5x+4y=30 Eqn 1
2x+3y=19 Eqn 2
Multiplying Eqn 1 by 2

Multiplying Eqn 2 by 5

Subtracting Eqn 3 from Eqn 4

Dividing both sides by 7

Putting y=5 in Eqn 1

Dividing both sides by 5

The price of one hat is $2 and price of one pair of mittens is $5.
