We know that the problem statement states that the number of ice cream sandwiches eaten together by Molly and Torry is 12.
Since Molly ate 5 and Torry ate n ice cream sandwiches, we can represent this in the equation below...
5 + n = 12
Answer:
F
Step-by-step explanation:
Because
Use double intercept formula
Y/b + x/a = 1
Where a and b is intercept
Answer:5/3 + 2/4 = 13
/6
= 2 1
/6 ≅ 2.1666667
Step-by-step explanation:
Answer:
10c = 20
5c = 5
Step-by-step explanation:
Let x be the number of 10c coins; let y be the number of 5c coins. The total is $2.25, so the amount of 10c and 5c coins will add to that. Simita has 25 coins, so x and y, the number of coins, will have to add to 25. Hence, solve the simultaneous equation.
10x + 5y = 225 (1) - times by 0
x + y = 25 (2) - times by 5
10x + 5y = 225 (1)
5x + 5y = 125 (2)
Then, take equation 2 away from equation 1.
5x = 100
x = 20
Substitute x back into the original equation.
x + y = 25
20 + y = 25
y = 5
