Step-by-step explanation:
subtract the whole equation by 85 on both sides to get v by itself on the left side
85-85-v=213-85
-v=128
Now we divide the whole equation by negative 1
-1v/-1=128/-1
v=-128
Hope that helps :)
Answer:
A) 5
Step-by-step explanation:
Since ABC and DEF are equal they will have the sum, you'll wanna plug in the numbers into the x spots on DEF. So instead of 4x-2, try 4(5)-2.
D and F:
4(5) = 20
20 - 2 = 18
A and C also equal 18

If t/5 = 7/r
and you flipped 7/r to r/7... flip t/5 too.
If t/5 = 7/r, then 7/r = 5/t
5/t should be your answer
hope this helps
