At a restaurant the cost for a breakfast taco and a small glass of milk is $2.05. The cost for 3 tacos and 4 small glasses of milk is $6.90. Write a pair of equations that can be used to determine t, the cost of a taco, and m, the cost of a small glass of milk. Use your equations to find the cost of each item.

Step-by-step explanation:

t +  m = 2.05 (i)

3t + 4m =6.90 (ii)

Multiply equation(i) by (-3)

(i)*(-3)     -3t - 3m = -6.15

(ii)          3t + 4m  = 6.90  {Now, add. So, t will be eliminated}

                    m   =$ 0.75

Substitute the value of m in equation(i)

t + 0.75 = 2.05

t  = 2.05 - 0.75

t = $ 1.30

step-by-step explanation:

i think it is everything has to equal 180 so, if i correct 4=c. 6=d. 8=a. 7=b. and the last question would be c. because they are parallel lines and they are congruent.

step-by-step explanation:

the reason everything has to equal to 180 is because that is how it works. i'm guessing that is its rule. 4 and 8 are congruent and parallel so, that would be 30+30 because they have the same number. it would equal 60. 6 and 7 are congruent and parallel so, that would be 30+30 because they have the same number. it would equal 60. 60+60 is 180. so, now you have your answer
