Substitute 5 and 3 for a and b in the original expression.
8(a+b)
8(5+3)
Using the rules of PEMDAS, solve the inside of the parentheses first, then multiply accordingly.
8(8)
<u>The final answer is 64.</u>
Answer:
x = 130°
Step-by-step explanation:
At the points of Tangency, A and B, the angle formed are equal to 90° based on the tangent theorem.
Therefore, m<A and m<B both have a degree measure of 90° each.
Thus, the sum of the interior angles of quadrilateral AOBC = 360° (sum of interior angles of a quadrilateral).
Therefore:
x + m<A + m<B + m<C = 360°
x + 90 + 90 + 50 = 360 (substitution)
x + 230 = 360
x = 360 - 230 (subtraction property of equality)
x = 130°
1/2(5x-6)-1/3(9x-5)+1
5/2x-3-3+5+1 distribute
5/2x-6+5+1 combine like terms
5/2
130 • .16 = 20.8 or 20 (4/5) or 104/5
Put the answer as 20.8 unless specified otherwise.
.16 is 16%
