You burn 265 calories running and then 7 calories per minute swimming.  

Your friend burns 273 calories running and then 11 calories per minute swimming.  

Let us assume that both of you swim for x minutes.  

Calories burnt by you = 265+7x  

Calories burnt by your friend = 273+11x  

Difference between both = 273+11x-(265+7x)  

= 273+11x-265-7x  

= 8+4x

Sammy served food to a group at a restaurant. The total cost of the food was $62.00. The sales tax is 6% of the cost of food. Th
alex41 [277]
Total cost = 62 + (6% of 62) + (20% of 62)

-  Find 6% of 62:
1% = 62 / 100 = 0.62
0.62 x 6 = 3.72

-  Find 20% of 62:
10% = 6.2
6.2 x 2 = 12.4

Add everything together:
62 + 12.4 + 3.72 = 78.12

The total cost was $78.12

The 5th term of linear sequence is 17
dedylja [7]

Answer:

397

Step-by-step explanation:

lets say there's an eqn which is y = mx + c, x is the term no. (5, 6 in the egs provided), y is the value corresponding to x (17, 21)

to find the 100th term sequence we need to find m and c. m is how much y changes when x increases by 1

in this case we can find m easily (m = 21-17 = 4)

now we have c left so just sub one of the egs given to what we have alrd found

17 = 4(5) + c

17 = 20 + c

c = - 3

so the eqn is y = 4x - 3, and we can solve for when x = 100

y = 4(100) - 3

y = 397

hope this isn't too confusing :^)
