a=7/2-3/10
Step-by-step explanation:
20a +158+6c= 120+60+48
20a +158+6c=228
20a =228-158-6c
20a =70-6c
a= 7/2 - 3/10
Answer:
120 + 60 + 48 would be the correct answer !
Step-by-step explanation:
Answer: S = 3.5
Step-by-step explanation:
We know that congruent means that the sides are equal. Knowing this, we can make an equation to solve for.
We can 2s+11=8s-10.
We can then subtract 2s from both sides, getting 11=6s-10.
We can then add 10 to both sides, getting 21=6s.
Dividing both sides by 6, we get 3.5=S.
