Answer:
BC = 60
Step-by-step explanation:
3X + X = 80 <---- X = BC
3X + X = 4X
4X = 80 <---- DIVIDE BOTH SIDES BY 4
4X ÷ 4 = X
80 ÷ 4 = 20
20 × 3 = 60
Answer:Let's solve for a.
d=
4
5
a+h
Step 1: Flip the equation.
4
5
a+h=d
Step 2: Add -h to both sides.
4
5
a+h+−h=d+−h
4
5
a=d−h
Step 3: Divide both sides by 4/5.
