Answer:
A and B are correct
Step-by-step explanation:
Student C is wrong because they broke up 3/4 into
2/2 + 1/2
but 2/2 + 1/2 = 3/2, which is not equal to 3/4
Answer:
25
Step-by-step explanation:
so you replace all the x's with 15 and it becomes
2×15-5
2×15=30
30-5=25
300 = 2(x + x + 10)
300 = 2(2x +10)
300 = 4x + 20
4x = 280
x = 70
x + 10 = 80
width = 80ft
answer <span>D) 80 feet</span>
The answer would be about 8/12 because you must convert 4/6 into 8/12. 8/12 + 3/12=11/12
1/4 would be about 3/12, so 11/12 - 3/12=8/12.
Answer:
one solution
Step-by-step explanation:
7x - 3 = 5x + 5 ( subtract 5x from both sides )
2x - 3 = 5 ( add 3 to both sides )
2x = 8 ( divide both sides by 2 )
x = 4
