Answer:
The soda costs 2.20 and the sandwich costs 7.70
Step-by-step explanation:
To find this, set the soda cost as x. We now know that the sandwich cost is 3.5x. Add these together and set equal to 9.90
x + 3.5x = 9.90
4.5x = 9.90
x = 2.20
This is the cost of the soda. Now we can multiply that by 3.5 to get the sandwich cost.
3.5 * 2.20 = 7.70
Answer:
y=2/3x-11/3
Step-by-step explanation:
to find the y intercept, you can input your values into the equation:
b=y1−m⋅x1
When you do that, you get:
b=−1−(2/3)⋅(4)=−11/3
When you convert that equation into y=mx+b form, you get:
y=2/3x-11/3

Answer:
A. 219.80 square centimeters
Step-by-step explanation:
The total surface area is given by ...
A = πr(r+s)
where r is the radius and s is the slant height. Filling in the given numbers, you get ...
A = 3.14·(5 cm)·(5 cm +9 cm) = 219.80 cm²
