Answer:
x = 7
Step-by-step explanation:
the smallest common denominator between 2 3 and 6 is 6. Multiply the original equation by 6
- 6(x/3 + x/6 = 7/2)
- 6(x / 3) = 2x
- 6(x/6) = x
- 6(7/2) = 3*7 = 21
Result
- 2x + x = 21
- 3x = 21
- 3x/3 = 21/3
- x = 7
Check
- 7/3 + 7/6 = 7/2
- 14/6 + 7/6 = ? 7/2
- 21/6 =? 7/2
- 21/6 = 3.5
- 7/2 = 3.5
Answer: x = 7
The reason that this is possible is because Marty's pizza is larger. For example you could compare a fun size candy bar to a full size. 5/6 of a fun size candy bar is still less than 4/6 of a full size. Hope thats helpful!
Let the number be n. Then 5n + 4 = n. simplifying, 4n = -4, and n = -1

Answer:
50
Step-by-step explanation:
8 x 4 + 9 -9 + 18
PEMDAS says multiply first
32 + 9 -9 + 18
Then add and subtract from left to right
41-9+18
32+18

Mult. 536 by 410. Hold the 0 for now and mult your final answer by 10.
Mult 536 by 41: The first partial product is (536)(1) = 536.
The second is (536)(4) = 2144.
Align these partial products as follows:
536
2144
----------
219760 (we held that final 0, remember?)
