SpyIntel [72]3 years ago

Answer:

Step-by-step explanation:

a = adult cost

c = child cost

a = c + $3

200a + 100c =$2100

^ each # of tickets sold

200(c+3) + 100c =$2100

200c + 600 + 100 c = 2100 combine like terms

300c + 600 = 2100 need variable only on one side of equal sign so you subtract 600 from each side of the = sign

300c = 1500 now divide by 300 on both sides to isolate variable

c = $5

Find the surface area of this rectangular prism. Be sure to include the correct unit in your answer.
nlexa [21]

Answer:

190 ft^2

Step-by-step explanation:

So first we need to find which equation we're using and since it's a rectangular prism we're going to use:

2Lw + 2wh + 2Lh

Now what we need to do is plug in the values

2*9*2 + 2*2*7 + 2*9*7

Now just multiply everything and then add it together.

36 + 28 + 126

Once you add everything together you get:

190

The question says to include the correct unit. It says that its feet, but we need to know if its feet squared (^2) or cubed (^3)

If it were area of the whole object, it would be cubed because it is all the area that the object takes up but since it's just the area of the surface it's going to be squared. Therefore, the answer is:

190 ft^2

If a number is an element of the set of real
kvasek [131]

Answer:

Option (A)

Step-by-step explanation:

A set of real numbers is a combination of both rational and irrational numbers.

But the elements in the sets of rational and irrational numbers will be different.

In short, rational and irrational number sets are the two subsets of real numbers.

Hence, the number is an element of either the set of rational numbers or the set of irrational numbers.

Option (A) is the correct option.
