Answer:
expression because an equation has to have a plus +×÷ or divsion sign to be an equation
X - rows of corn,
y - rows of lettuce:
x = 2.5 y
x + y = 455
------------------
2.5 y + y = 455
3.5 y = 455
y = 455 : 3.5
y = 130
x = 2.5 * 130 = 325
Answer: The farmer plans to plant 325 rows of corn and 130 rows of lettuce.
Sophie would earn $27.36 from interest because 456 divided by 0.06 equals 27.36
Hi there!
Let's first have a look at the basic goniometric statements, which say the following:

When we're looking from the point of view of angle G, we have the following data:
- The length of the opposite side is 15
- The length of the adjecent side is 8
- The length of the hypotenuse is 17
Now plug in this data into our general formulae.

Hence, answer B. is correct.
~ Hope this helps you!
