Answer:
Tacos for adults: 13*3
Tacos for children: 17*1
Total: 39+17
=56
And in each package there will be 8 tacos
So, 56/8 = 7 = No. of tacos needed.
So the corrrect answer is<u> A 7, because (13 x 3 + 17) + 8 = 7</u>
Answer: y = -5; x = -2
Step-by-step explanation:
- 5y – 10x=45
- 3y + 10x = -5
Combining both equations
-8y = 40
y= 40/ -8
y = -5
Substitute y = -5 into any of the equations to get the value of x
-5 (-5) - 10x = 45
25 -10× = 45
-10x =45 -25
-10× = 20
Divide both sides by -10
x = -2

Answer:
The speed of Murphy to cover one lap is 
miles per hour .
Step-by-step explanation:
Given as :
The total distance of one lap around track = d = 
miles
The time taken by Murphy to walk one lap = t = 
hours
Let The speed of Murphy = s miles per hour
<u>Now, According to question</u>
Speed = Distance × Time
Or, s = d × t
Or, s = miles × hours
Or, s = 
mi/h
Or, s = mi/h
So,The speed of Murphy = s = miles per hour
Hence, The speed of Murphy to cover one lap is miles per hour . Answer
The first one is angle side angle
The second one is side angle side
The last one is angle side angle
