That’s the answer for that question
Answer:
Step-by-step explanation:
1.5m
(2500mm)/(1000 mm/m) = 2.5m
(850mm)/(1000 mm/m) = 0.85m
4.8m
Add the number of meters:
1.5 + 2.5 + 0.85 + 4.8 = 9.65m
Answer:
56 is 70% of 80 students.
Step-by-step explanation:
70% = 0.7
56 divided by 0.7 = 80
Answer:
The results don't make sense
Step-by-step explanation:
We can solve by means of a 2x2 system of equations, we have to:
"x" is the number of children's tickets
"y" is the number of adult tickets
Thus:
8 * x + 8.75 * y = 259
x + y = 35 => x = 35 - y
replacing we have:
8 * (35 - y) + 8.75 * y = 259
280 - 8 * y + 8.75 * y = 259
- 8 * y + 8.75 * y = 259 - 280
0.75 * y = -21
y = -21 / 0.75
y = -28
Thus:
x = 35 - (-28) = 63
With these results we notice that the problem has inconsistency, since the value of the tickets cannot be given a negative number, I recommend reviewing the problem, since the approach is correct.
