When comparing to thing with same rate, set up a proportion:
Inches/cost
13/.78=33/x
(13)(x)=(.78)(33) [cross multiplied]
13x=25.74 [simplified]
13/13x=25.74/13 [division property]
x=1.98
33 inches of wire will cost $1.98.
X-X^2/ (x-3)^2 try that I’m not 100% sure tho
My answer that i have gotten is 280
It would be:
Tens | Ones
3 + 4
2 + 14
1 + 24
0 + 34
Hope this helped! c:
Well, 10x4=40 because 10+10+10+10=40 and that means your answer must be 40 ones or you asked something else.
