What does X=?<br> I cannot figure out how to solve this problem please help!
Alona [7]

Answer:

Step-by-step explanation:

S = (n - 2).180°

n = quantity of sides

S = all angles addition

S = (5 - 2).180°

S = 3.180°

S = 540°

104 + 117 + 100 + 124 + x = 540

445 + x = 540

x = 540 - 445

x = 95°

I hope I've helped you.

linear equation in slope intercept form for this situation. mary is selling popcorn for $5.00 per bucket and hotdogs for $4.75 e
3241004551 [841]

Answer:

standard form to represent the situation equation is 5a + 4.75b = 72.50

Step-by-step explanation:

given data

selling popcorn = $5.00

hotdogs = $4.75

makes =  $72.50

solution

we consider here number of bucket sold = a

and number of hotdogs sold = b

Then after 1 hour she makes $72.50

equation for number of popcorn and number of hotdogs sold after an 1 hour  is express as

$72.50 = number of bucket sold × price of popcorn per bucket + number of hotdogs sold × price of hotdog   ...............................1

put here value and we get

72.50 = 5 × a + (4.75) × b  

5 a + 4.75 b = 72.50

so here equation is equivalent to the standard form in the  linear equation that is express  ( Ax + By = C   )

and here A and B are non zero with  A, B and C all three are real number

so standard form to represent the situation equation is 5a + 4.75b = 72.50

No. Aaron ate more because 5/6 is a larger fraction than 2/3.
