Hello there,
So by using the formula xy=k just plug in both x and y.
So this would be (7)(3)=k
Which means 21=k
Hope this helped!
Answer:
Step-by-step explanation:I think it 24
Let number of driveways , she shoveled on Sunday = x
And for 4 driveways , Kendra charges = 4*11=44
Therefore,
143 = 44 + 11x
And that's the model for the given situation .
Subtracting 44 from both sides,
143-44 = 11x
99 = 11x
Dividing both sides by 11
x = 9
Therefore she shoveled 9 driveways on Sunday .
ANSWER: 4/21 teaspoons of salt
2 1/3 flour : 1/3 salt
2 1/3 cups of flour = 7/3
To get 2 cup of flour we need 3/3 so we take away 4/3 of the flour
7/3 ÷ 4/3 = 1.75
so we ÷ both by 1.75 to get the same ratio
1/3 teaspoons ÷ 1.75 = 4/21 teaspoons of salt
