Answer:
$120
Step-by-step explanation:
✓An expression for this can be written as
f(n) = 20(n)
Where n= number of weeks of the lesson.
✓Then the cost for 6 weeks of lessons will be f(6)
f(6) = 20(6)
=$120
Hence, The cost is $120
Answer:
Integers, Terminating Decimals, Recurring Decimals, Proper and Improper Fractions.
Step-by-step explanation:
The following subset of the real number system can be written in the form , b≠0.
Integers(ℤ): These are positive and negative whole numbers. For example, 5 can be written as
Terminating Decimals: These are fractions that when converted to decimal numbers have an end.
e.g.
Recurring Decimals: These are fractions that when converted to decimal numbers do not have an end.
e.g.
Proper Fractions: These are fractions of the form where a<b. An examples is
Improper Fractions: These are fractions of the form where a>b. An examples is
Hey there!
<u>Solve </u><u>for </u><u>k </u><u>:</u>
k = -15 ✅
18 = -k + 3
<em>></em><em>></em><em> </em><em>Substrat </em><em>3</em><em> </em><em>from </em><em>both </em><em>sides </em><em>:</em>
18 - 3 = -k + 3 - 3
15 = -k
<em>></em><em>></em><em> </em><em>Dive</em><em> </em><em>each </em><em>side </em><em>by </em><em>-</em><em>1</em><em> </em><em>:</em>
15 / -1 = -k / -1
-15 = k
Therefore, your answer is k = -15
