Answer: 87.5
Step-by-step explanation:
180= 2x+15
-15 -15
175= 2x
175/2= 87.5
4/3x - 1/2 = 0 Given
4/3x = 1/2 Add 1/2 to both sides
x = 3/8 Multiply each side by 3/4
It is important when doing equations like these to remember that you need to multiply by the reciprocal of the fraction, not divide by it. For example, if another you have 1/2x = 1, you need to multiply by 2/1 or 2, not divide by 1/2.
Answer:
107.500
Step-by-step explanation:
5.450.000-75.000=5.375.000
5.375.000:12 1/2=5.375.000:25/2=5.375.000*2/25=430.000
430.000:4=107.500
+ and - ,
* and :
are inverse operations
Where it is an operation and the result is a number , we have to do the inverse operation for finding the initial number.
verifying :
107.500*4*12 1/2+75.000=5.450.000
Answer:
I think number B
Step-by-step explanation:
I plugged it in the calculator. And then they both were zero.
Plain : Spotted : Striped socks are in the ratio of 5 : 3 : 8
So we can say that number of plain socks = 5x
Number of spotted socks = 3x
Number of striped socks = 8x
Hence, total number of socks = 5x + 3x + 8x = 16x
⇒ Fraction of Striped Socks = 
⇒ Fraction of Striped Socks = 
⇒ Fraction of Striped Socks = 
Hence, of Alex's socks are striped
