The Dial and the Lewis families when to Taco Box for dinner. The Dials bought 3

pychu [463]

Answer:

A burrito costs $8, while a taco costs $6.

Step-by-step explanation:

Given that the Dial and the Lewis families when to Taco Box for dinner, and the Dials bought 3 burrito meals and 4 taco meals for $ 48, while the Lewis' bought 6 burrito meals and 2 taco meals for $ 60, to determine how much does a burrito meal cost and how much does a taco meal cost make the following calculations:

3B + 4T = 48

3B = 48 - 4T

6B + 2T = 60

6B = 60 - 2T

3B = 30 - 1T

30 - 1T = 48 - 4T

30 = 48 - 4T + 1T

30 - 48 = -3T

-18 = -3T

-6 = -T

6 = T

3B + 4x6 = 48

3B + 24 = 48

3B = 24

B = 24/8

B = 8

6x8 + 2x6 = 60

48 + 12 = 60

60 = 60

Thus, a burrito costs $ 8, while a taco costs $ 6.

Lera25 [3.4K]

Ok so first you take $64.80 and multiply it by 2.5. You get $162. Now take $162 and subtract $20 from it. You are left with $142.

(i) 809, 708, 607, _____, _ class 4<br>__class 4

schepotkina [342]

Answer:

809, 708, 607, 506, 405, 304, 203, 102, 1, -100

Step-by-step explanation:

809, 708, 607, _____, _______

First term = 809

Second term = 708

Third term = 607

Difference between first term and second term = 809 - 708

= 101

Difference between second term and third term = 708 - 607

= 101

Therefore, the common difference is 101

Fourth term = 607 - 101

= 506

Fifth term = 506 - 101

= 405

Sixth term = 405 - 101

= 304

Seventh term = 304 - 101

= 203

Eighth term = 203 - 101

= 102

Ninth term = 102 - 101

= 1

Tenth term = 1 - 101

= - 100

809, 708, 607, 506, 405, 304, 203, 102, 1, -100
