They have had three local matches, a, b and c, and will attend a district match. District match points count for twice the number of points than local matches do. Choose the equation that would help Tisha find how many points they need to earn in the district match, d, to advance.

d equals T minus a minus b minus c all over 2
d equals T over 2 minus a minus b minus c
d equals T plus a plus b plus c all over 2

An equation is formed of two equal expressions. The correct option is A.

What is an equation?

An equation is formed when two equal expressions are equated together with the help of an equal sign '='.

Given Tisha has 3 local matches, therefore, a, b, c. Also, she has a district match, and district match points count for twice the number of points than local matches do. Therefore, the total points will be,

2d + a+ b+ c

Since the total point should be equal to T, therefore, we can write,

T = 2d + a+ b + c

T - a - b - c = 2d

d = (T - a - b - c)/2

Hence, the correct option is A.
