The really short answer is, there are 5 weeks, and the temperature dropped a total of -15 celsius on those 5 weeks, how many times does 5 go into -15? -15/5 or -3, so each week, evenly it dropped -3 celsius, and after 5 weeks, it added up to -15 celsius total from the first one.
so in the first week, or week 1, it dropped -3(1), on week 2 it dropped -3(2) on week "w" it dropped -3(w), f(w) = -3w.
see the attached figure to better understand the problem
we know that
In a parallelogram opposite angles are congruent, and consecutive angles are supplementary
So
in this problem
∠Y=
°
∠W=∠Y
∠W=°
∠Z=∠X
∠Y+∠Z=
°
∠Z=
∠Z=
°
∠X=∠Z
∠X=°
therefore
the answer is
∠Y=°
∠W=°
∠X=°
∠Z=°
Answer:
Real numbers are Closed under multiplication.
Irrational numbers are Not Closed under division.
Integers are Closed under subtraction.
Positive rational numbers are Closed under addition.
Step-by-step explanation:
a) The product of any two real numbers is a real number, so the set is closed.
b) In some cases, the quotient may be rational. (√18)/(√2) = 3, for example. So, the set is not closed.
c) The difference of any two integers is an integer, so the set is closed.
d) The sum of any two positive rational numbers is a postive rational number, so the set is closed.
Sorry if its out of order but i hope it helps enough
The response is that the data is not precise
You can write the expression 6(y) in the following ways:
6 × y
y × 6
6y
