Answer:
157.5.
Step-by-step explanation:
(155 + 160) / 2
= 315/2
= 157.5.
Answer:
Probably because learning to do polynomials by hand boosts understanding of the topic and improves general algebraic solving ability,both of which are required in further topics like advanced calculus and algebra
Answer:
Step-by-step explanation:
According the Triangle sum theorem:
m<T + m<U + m<V =180
x + 2x + x + 80 = 180
solve: x=25
Therefore m<T = 25, m<U = 50, and m<V = 105
In this question, you're solving for n.
Solve for n:
5(1 - 5n) = -4n+5
<em>Use the distributive property</em>
5 - 25n = -4n + 5
<em>Add 25n to both sides</em>
5 = 21n + 5
<em>Subtract 5 from both sides</em>
0 = 21n
<em>Divide both sides by 21</em>
n = 0
Answer:
n = 0
