Answer:
Step-by-step explanation:
-8-4v=40 add 8 to both sides
-4v=32 divide both sides by -4
v= -8
3v+2v=25
5v=25 divide both sides by 5
v=5
x/2 - 8 = -14 add 8 to both sides
x/2= - 6
-6 * 2= -12
check
-12/2-8=-14
-6-8=-14
-14= -14
-6+n/3= -3 add 6 to both sides
n/3=3
3*3=9
check
-6+9= -3
-3 = -3
Step-by-step explanation:
a x^2/4
b -x^2/4+3
c 4x^2
d -x^2
Set up multiplication/division of proportions to cancel out units that you don't want and to introduce units that you do want in your final solution...
2678cm(in/2.54cm)(ft/12in)=2678/30.48 ft≈87.86 ft (to nearest hundredth)
i can help, but you need to write the whole question..
