Answer:
Step-by-step explanation:
T = 4c + 25....where c = # of classes and T = total cost
2 classes...so sub in 2 for c and solve for T
T = 4(2) + 25
T = 8 + 25
T = 33 <==== with 2 classes ,its $ 33
4 classes....so sub in 4 for c and solve for T
T = 4(4) + 25
T = 16 + 25
T = 41 <==== with 4 classes, its $ 41
8 classes....sub in 8 for c
T = 4(8) + 25
T = 32 + 25
T = $ 57 <==== with 8 classes, its $ 57
10 classes...sub in 10 for c
T = 4(10) + 25
T = 40 + 25
T = 65 <===== with 10 classes, its $ 65
Answer:
The answer is: 181.5 square centimeters.
Step-by-step explanation:
The cube has six faces, and each face is a square with sides of length 5.5, so the area of one of this faces is 
, adding the six faces, we get the answer:

Answer:
8.
Denote the equation : y = ax + b
Use the first 2 values of x and y in table:
3a + b = 21
5a + b = 35
Subtract the 2 equations:
=> 2a = 14 => a = 7 => b = 21 - 3 x 7 = 0
=> The solution is y = 7x
9.
Denote the equation : y = ax + b
Use the first 2 values of x and y in table:
5a + b = 17
10a + b = 22
Subtract the 2 equations:
=> 5a = 5 => a = 1 => b = 17 - 5 x 1 = 17 - 5 = 12
=> The solution is y = x + 12
Hope this helps!

Answer:
Step-by-step explanation:
Yes
Theorem 8.3: If two angles are complementary to the same angle, then these two angles are congruent.
∠A and ∠B are complementary, and ∠C and ∠B are complementary.
Given: ∠A and ∠B are complementary, and ∠C and ∠B are complementary.
Prove: ∠A ~= ∠C.
Statements Reasons
1. ∠A and ∠B are complementary, and ∠C and ∠B are complementary. Given
2. m∠A + m∠B = 90º , m∠C + m∠B = 90º Definition of complementary
3. m∠A = 90 º - m∠B, m∠C = 90º - m∠B Subtraction property of equality
4. m∠A = m∠C Substitution (step 3)
5. ∠A ~= ∠C Definition of ~=
