Answer:
Tasha ordered 9 ounces of salad
Step-by-step explanation:
<u><em>The complete question is</em></u>
Tasha ordered soup and salad for lunch. The soup cost 15 cents per ounce, and the salad cost 20 cents per ounce. If Tasha ordered 10 ounces of soup for lunch and the total cost was $3.30, how many ounces of salad did
Tasha order?
Let
x -----> the ounces of soup ordered
y -----> the ounces of salad ordered
we know that
The ounces of soup ordered multiplied by their cost plus the ounces of salad ordered multiplied by their cost must be equal to $3.30
so
-----> equation A
substitute the value of x in the equation A and solve for y
Subtract 1.50 both sides
Divide by 0.20 both sides
therefore
Tasha ordered 9 ounces of salad
Answer:
y = 2/3x + 19/3
Step-by-step explanation:
First, this is your current equation: y = 2/3x + b. Plug in your point to the equation, it should look like this: 5 = 2/3(-2) + b. 2/3 times -2 equals -4/3. So, this is what your equation should look like: 5 = -4/3 + b. Add 4/3 to both sides of the equation to get 19/3 = b. Go back to your original equation and plug 19/3 to b. This is your final equation: y = 2/3x + 19/3. Hope this helped!
