Answer:
a = 4
Step-by-step explanation:
So your goal here is to get the variable on just one side, so add 4a to both sides. This cancels out the 4a on of of the sides and puts a on the other side. The new equation is 8 = -2a + 4a. Combine like terms to get 8 = 2a. Divide both sides by 2 to get a = 4. You can check your work by replacing a with 4:
8 - 4(4) = -2(4)
8 - 16 = -8
-8 = -8
Since the final result is true, (-8 does equal -8,) a = 4.

What is the number of sides of a regular polygon if each interior angle measures 160°?
Answer:
18
Step-by-step explanation:
180-160 = 20 which equals the exterior angle
the sum of exterior angles is 360 so 360/20 = the number of sides as there is an exterior angle for every side
360/20 = 18

Compare/contrast linear functions and exponential functions.
I need at least 3 to 4 paragraphs
Please Help!
Answer:
Linear functions is just basically straight lines while exponential functions also just curved lines. You can actually also find them by just the change in the y. If the same number is just being added to y, then most likely the function has a constant change and is also linear. Exponential functions will most likely be in the way(form) of the equation y = (1 + r) x. HOPE THIS HELPS!
Step-by-step explanation
just read about one thing and right about it and the other and just find the compare/contrast! :)

The total cost of purchasing a leotard, including tax,
was $19.61. Find the cost of the leotard before sales
tax.
Answer:
$18.43
Step-by-step explanation:
19.61 decrease 6% =
19.61 × (1 - 6%) = 19.61 × (1 - 0.06) = 18.4334
The cost of the leotard before sales tax is $18.5
What is the formula to calculate sale tax ?The sales tax is calculated by multiplying the total sales or selling price by the rate of sales tax.
Amount of sales tax = rate of sales tax × Total sales
Rate of sales tax = percent of sales tax / 100
Let the cost of leotard before tax be x
Given that sales tax of 6% is applied over x
The the amount of sales tax =( 6/100) ×x = 3x / 50
The total cost after applying sales = x + (3x/50) = 53x/50
Given that the total cost of purchasing a leotard including tax = $19.61
⇒ 53x/50 = 19.61
⇒53x = 19.61×50
⇒ x = 980.5/53 = 18.5
Therefore, the cost of the leotard before sales tax is $18.5

What is the equation of the line ?
Which is the better buy? How do you know?
A. 7 ounces of tomato sauce for $2.10
B. 28 ounces of tomato sauce for $5.60
Hello, 928747! I can help you.
So we are trying to find which has a better deal. We can do this by comparing them.
If 7 ounces is $2.10 then we need to turn that into 28 ounces.
Using common multiplication, we know that 7 x 4 = 28.
So we would do the same thing to the price.
2.10 x 4 = 8.4
So, A is $8.40 for 28 ounces.
B is $5.60 for 28 ounces.
Therefore, B has the better deal.
