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.

Jay and Blair went fishing. Together, they caught 27 fish. Jay caught 2 times as many fish as Blair. How many fish did Jay and B
enyata [817]
<span>Leah,  Let x=Blair's fish and 2x= Jay's fish; yet together they caught 27 fish.  So, x + 2x=27;  Combine the like terms.  So, 3x=27;  Now divide both sides of the equation by 3, therefore, x=9 which is the amt of fish Blair caught.  So, 2(9)=18 is the amt of fish Jay caught.  Check:  9 +2(9)=27;  27=27.</span>
