Step-by-step explanation
3.2x+5.7=2.5x. X=-8.142857
10.1x-1.6x+44=-7 x=-6
7.9x+x+4=1.1x-16 x=-2.564103
1/4x+5/2x-2=4-1/4x x=2
Answer:
7=x
Step-by-step explanation:
multiply 5 and 2x by 2, you'll then have (10+4x)=-4+6x. Then add 4 to both sides and you have (14+4x)=6x. Subtract 4x from both sides and that'll get you 14=2x and you divide 2 from each side to get x by itself so 7 is your answer.
AB=root (11-3)^2-(10-4)^2
= root 64-36
= root 28 units
$0.20 Because since one ribbon for one foot equals $0.10 (10 cents), you have two feet so you would have to multiply or add $0.10 and $0.10 by multiplying, you would have to multiply 10 two times which would give you 20. To add you would add 10 plus 10 and you would get yet again 30. After that you just put the form as cents which would be $0.20 :)
