2/3 would be the answer hope this helps.
Answer:
#3
Step-by-step explanation:
Answer:
-3=a
Step-by-step explanation:
-a+4a-9=8a+6
3a-9=8a+6
3a-9-6=8a+6-6
3a-15=8a
3a-3a-15=8a-3a
-15=5a
-15/5=5a/5
-3=a
Answer:
24
Step-by-step explanation:
6.21+6.21=5.7+5.7=23.82
23.82 rounds to 24
(perimeter is all of the sides combined)
Answer:
25. Not a solution
26. Yes a solution
27. y= 2/3 x
28. y=3x+16
Step-by-step explanation:
25. The solution to a linear equation is the point (x,y). To find if an (x,y) is a solution, substitute it into the equation and see if it works.
y=4x-4 and (8,3)
3=4(8)-4
3=32-4
3=28
False
Not a solution.
26. Repeat 25 to solve 26 with y=5x-5 and (0,-5)
y=5x-5 and (0,-5)
-5=5(0)-5
-5=0-5
-5=-5
True
Yes a solution.
27. This line crosses through the origin is proportional and therefore has the form y=mx. It also has a gentle slant meaning that is less than 1/2 and goes in a positive direction. This means it is y=2/3 x.
28. Use inverse operations to rearrange the equation.
y-3x=16
y=16+3x
y=3x+16
