Expand the given expression.
22.5 + 7(n - 3.4) = 22.5 + 7*n + 7*(-3.4)

Multiply +7 and  -3.4 to obtain - 23.8. Therefore
22.5 + 7(n - 3.4) = 22.5 + 7n - 23.8

Write the constant terms together. Therefore
22.5 + 7(n - 3.4) = 7n + 22.5 - 23.8 = 7n - 1.3

Answer: 7n - 1.3

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

Answer:

d=45h

Step-by-step explanation:

If we look at the chart, it shows that 1 hour is equal to 45 miles. Then, 2 hours is equal to 90 miles and so on. This means that for every hour the distance is 45 miles. Therefore, the distance=45 miles times the number of hours. This is equivalent to d=45h The number 45 is equal to the number of miles and the "h" is equal to the amount of hours. I hope I didnt confuse you in the process of writing this and have a good day!
