This is the answer 14000 m
1 hundredth+3 tenths= 3 hundredths
Step-by-step explanation:
Substitute the y in the 1st equation with the 2nd equation.
7x + 10(2x + 9) = 36
7x + 20x + 90 = 36
27x + 90 = 36
3x + 10 = 4
3x = -6
x = -2
So now we can find y.
y = 2x + 9 = 2(-2) + 9 = (-4) + 9 = 5.
So x = -2, y = 5.
Answer: Yes, the amount can buy either of them a second salad or a drink.
Step-by-step explanation:
Since a salad cost $2.49 and a bottle of drink cost $0.99, therefore for both of them the total amount they need to spend is (2×$2.49)+(2×$0.99)
= $4.98+$1.98
= $6.96
This is the amount for both of them to get a first salad and a drink.
Since they both have $8.00 with them, their balance will be $8.00-$6.96 which is $1.04
The balance can buy one of them second drink then that is $0.99. So yes, the amount can buy either of them a second salad or a drink.
