<span>11d=81-16d
Add 16d to both sides
27d=81
Divide 27 on both sides
Final Answer: d = 3</span>
Answer:
32 − 8
Step-by-step explanation:
1. Rearrange terms
− 4 (2 − 8)
− 4 (− 8 + 2)
2. Distribute
− 4 (− 8 + 2)
<u><em>32x - 8</em></u>
Answer:
p = 2.7x - 20
p(90) = $223
Step-by-step explanation:
revenue → f(x) = 3x ,where x is the number of downloads.
the statement “Your profit p is $20 less than 90% of the revenue for x downloads”

the profit for 90 downloads :
= p(90)
= 2.7×(90) - 20
= $223

Answer:
Part 1)
Part 2)
Part 3)
Part 4)
Step-by-step explanation:
step 1
Find the length side c
Applying the Pythagoras Theorem
substitute the given values
step 2
Fin the measure of angle B
we know that
In the right triangle
substitute the given values
step 3
Find the measure of angle A
we know that
The measure of interior angles in a triangle must be equal to 180 degrees
so
∠A+∠B+∠C=180°
Remember that in a right triangle the measure of angle C is 90 degrees
we have
substitute
