For this case, the first thing we must do is define variables.
We have then:
x: cost of tacos
y: cost of enchiladas.
We write the system of equations:
2x + 3y = 7.80
3x + 5y = 12.70
Solving the system we have:
x = 0.9 $
y = 2 $
Answer:
each taco and each enchilada was:
x = 0.9 $
y = 2 $
Answer:
1 17/40
Step-by-step explanation:
5/8+4/5
We need to get a common denominator of 40
5/6 * 5/5 = 25/40
4/5*8/8 =32/40
25/40 + 32/40 = 57/40
57/40 = 40/40 + 17/40 = 1 17/40
The correct answer will be 3.
Why?
If v = m + 3 what is m?
Well it's says that D = m/v and D = 3/6.
So if M is 3, what number can you add my 3 that is gonna equal to V (6).
3 + 3 = 6 and that's how I got my answer.
That really does seem correct lol I think the variable is right since 5 represents 3x so 9 +3(5) =24
