Answer: a.) -1 2/3
explanation: -2 1/6 - 1 1/4= -13/6 - 5/4= -41/12 ; 1 3/4= 7/4 ; -41/12 + 7/4= -5/3 ; -5/3= -1 2/3
Answer:60°
Step-by-step explanation: First, think about the rule of the degrees for all triangles. Angles must equal 180°.
Second, because all angles must equal 180°, see that the triangle given has equal sides (assuming this, because no other measurements are given).
Equilateral triangles have equal angles, meaning 60° for each angle.
Answer:
so x = 5 is not true statement
Step-by-step explanation:
well to prove x = 5 you need to get get alone or solve for x
3x = 10-5 --> 3x = 5
now you need to get x alone do this by dividing 3 by both sides
3x = 5 --> x = 5/3
x = 1.6
Answer:
Step-by-step explanation:
An index number is a number which is raised to a power. The power, also known as the index, tells you how many times you have to multiply the number by itself. For example, 2^5 means that you have to multiply 2 by itself five times = 2×2×2×2×2 = 32. There are a number of important rules of index numbers: y^a × y^b = y.
As the exponent is negative, we can rewrite the expression as (125/64) raised to the power 2/3.
So, (125/64) raised to the power 2/3 can also be written as [(5/4) raised to the power 3] raised to the power 2/3. The exponents will multiply and the final exponent will be 2.
Hence the answer will be (5/4) squared.
Therefore the answer is (24/16).
