Billies decided to go to an mpty mall and walk, dance and sing inside the mall, while there she visited 100 different businesses that where either retail stores or resturants. The number of Retail stores she visited is 8 less than three times the number of restaurants she visited,
1. define variables and set up a system of two linear equations to represent this situation
2. how many solutions does the system have?
3. How many restaurants did she visit?
4. how many retail stores did she visit?
5. check your solution to verify that it satisfies both of yuor equation from part 1

∠acb = 8°

step-by-step explanation:

∠xba lies on the circle and is half the measure of the intercepted arc ax

hence

measure of arc ax = 2 × 42° = 84°

∠acb is outside the circle and is

∠acb = (arcab - arcax ), hence

∠acb = 0.5 (100 - 84) = 0.5 × 16° = 8°

yeah i know the problem you need. i am taking it right now. the answer is step 3

to find the unit price of an object, you divide the price by object. you are trying to find out how much an object cost per unit.

for instance, lets say you have 50lb of ice cream(object) that cost 8.00 dollars(price). to find the unit cost, we take the 8.00 and divide it by 50, which will give us .16 cents per pound. we can check this by multiplying .16 by 50 = 8.00

so

object = e2

price = d2

unit price = c2

formula for c2:

=d2 / e2

so in my example about ice cream, we would have the following.

e2 = 50

d2 = 8.00

c2 formula:

=d2 / e2
