11. The two angles are vertical angles, which mean they are equal to each other.
14x - 5 = 13x
Add 5 to both sides:
14x = 13x + 5
Subtract 13x from both sides:
x = 5
12. The two angles are supplementary and when added together need to equal 180 degrees.
5x -20 + 3x = 180
Combine like terms:
8x -20 = 180
Add 20 to both sides:
8x = 200
Divide both sides by 8:
x = 200 /8
x = 25
Answer: v <= 1
Step-by-step explanation:
When you have a variable by a number, you do the opposite of multiplying, so you divide
Since there's only 14v you divide 14 from itself leaving just the variable
14 ÷ 14 = 1
You repeat this and divide on the other side
14 ÷ 14 = 1
Since you arent dividing by a negative on both sides, the arrow stays the same
v <= 1
Hope this helps!
X-15+9-4=x-10 there are ten fewer people after the second stop than the original amount
Since it’s asking for square inches on a rectangular prism, this is solving for surface area. So we use the following formula:
2(h*w)+2(h*l)+2(w*l)=A
2(10*8)+2(10*12)+2(8*12)
2(80)+2(120)+2(96)
160+240+192
592
592 sq. in.
Congruent is the same size and same shape. When a ray bisects an angle, the two newly created angles will be congruent, since the ray went right in the middle of the first angle (so in this case, ABC and DBC will be congruent)
