Answer:
⊥
Step-by-step explanation:
d and b meet at a 90 degree angle ( as shown by the box)
The lines are perpendicular (⊥)
If it gives you your total, and another number, divide the 2
example:
25 • x = 75
75/25= 3
x=3
I cannot see the picture ?
Answer:
1. x=-6
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
3(2x+3)−4x=−3
(3)(2x)+(3)(3)+−4x=−3(Distribute)
6x+9+−4x=−3
(6x+−4x)+(9)=−3(Combine Like Terms)
2x+9=−3
2x+9=−3
Step 2: Subtract 9 from both sides.
2x+9−9=−3−9
2x=−12
Step 3: Divide both sides by 2.
x=-6
