Answer:
a=7.85-1/2^b
Step-by-step explanation:
2a=15.7-b Move variable to the right side and change its sign
2a=15.7-b Divide both sides of the equation by 2
a=7.85-1/2^b The final solution for a is
Two figures are congruent if and only if there exists one or more rigid motions which will map one figure onto the other.

Answer:
This is trapezium.
Area of this figure =1/2h(d1-d2)
1/2×5(14-8)
=30/2
=15cm^2
Angle JML Angle LKJ & Angle MJK = MLK
Why it's correct:
In a parallelogram the opposite angles are congruent (as well as the opposite sides
So, first turn your fractions into decimals. ⅞ = 0.875 which rounded is 0.88. 4/5 = 0.8. Next, put the decimals into the equation to replace the fractions. 0.88 + 4.2 - 0.8. Next solve the problem. So 0.88 + 4.2 = 5.08. Now your equation should look like this 5.08 - 0.8. Then subtract 0.8 from 5.08 which gives you 4.28. So 4.28 is your answer.
