Answer
A. 42 tickets
Explanation
Since everyone must go on the ride together the number of tickets must be a multiple of 8 (since there are 8 people). 42 is the only number that is not a multiple of 8.
Answer:
1800
Step-by-step explanation:
→ First of all we need to find the prime factorisation of the numbers.
18 = 2 × 3 × 3 or 2 × 3²
40 = 2 × 2 × 2 × 5 or 2³ × 5
75 = 3 × 5 × 5 or 5² × 3
→ Now find the number that appear twice or more and write them down
3 and 3 from 18
2, 2 and 2 from 40
5 and 5 from 75
→ Now multiply all of these numbers together
3 × 3 × 2 × 2 × 2 × 5 × 5 = 3² × 2³ × 5² = 1800
Answer:
x =12
Step-by-step explanation:
we have:
-2(4-x)-5=11
apply distributive property:
-2*4 +2*x -5=11
we have:
-8 +2x -5 =11
2x -13 =11
2x = 11+13
2x= 24
x = 24/2
finally we have the x value:
x =12
