4 - 4 + 4 = 4.
four minus for plus four equals four.
Answer: 32/56, 0.57, 57% rounded = 60%
Step-by-step explanation: 8 times 7 =56 and 8 times 4= 32. our fraction is 32/56. divide 32 by 56 to make out a decimal= 0.57. Multiply 0.57 by 100 to make out a percent = 57%
The way you wrote it could have 2 meanings:
Sum of twice a and 4 could be:
2a+4 or 2(a+4) which will give different results.
In the first case:
2a+4
a= 4/2
a= 2
So the sum would be 2*2+4 = 4+4 = 8
In the second case:
2(a+4) = 2a + 2*4 = 2a + 8
a= 8/2
a=4
2(4+4) = 2*8 = 16
Well the question is written wrong but I think is 30
