a. 60% of 120 is 72. 72 +120 is 192. they will sell the bike for $192
b. 30% of 192 is 57.6. 192-57.6 =134.4. the sale price is $134.40
c. they will make $14.40 because $134.40-$120=$14.40
I can’t see the table, more info plz
Answer:
k(3n) = 9n² + 9n
General Formulas and Concepts:
Order of Operations: BPEMDAS
- Substitution and evaluation
Step-by-step explanation:
<u>Step 1: Define</u>
k(n) = n² + 3n
k(3n) is n = 3n
<u>Step 2: Solve</u>
- Substitute: k(3n) = (3n)² + 3(3n)
- Exponents: k(3n) = 9n² + 3(3n)
- Multiply: k(3n) = 9n² + 9n
Answer:
b, c e
Step-by-step explanation:
A congruence statement lists corresponding parts in the same order. CPCTC says corresponding parts are congruent.
__
To see if any particular statement is consistent with CPCTC, identify the locations of the referenced parts in the congruence statement. If they match, the congruence is true
a. l = r ... jkl = rst . . . . not in the same place
b. jk = rs ... jkl = rst . . . . a match; true
c. k = s ... jkl = rst . . . . a match; true
d. j = s ... inconsistent with (c)
e. kl = st ... jkl = rst . . . . a match; true
f. jl = rs ... inconsistent with (b)
Statements b, c, e are consistent with the congruence statement, and are true by CPCTC.
