Answer:
10y+5
Step-by-step explanation:
5 x 2y = 10y
5 x 1 = 5
Answer: 8.1
Step-by-step explanation: How you convert a mixed number into a decimal is taking the whole number (not the fraction part) and putting it in front of the decimal, then you get the fraction's denominator to 10 multiply if needed, then you take the fractions top number and put it after the decimal, Now your converted!

(i)
∠BAD + ∠ABD + ∠ADB = 180 <em>the sum of the angles of a triangle equals 180°</em>
70 + 50 + ∠ADB = 180 <em>substituted given information</em>
∠ADB = 60 <em>subtraction property (subtracted 70 and 50)</em>
∠ABD + ∠BDC = ∠ADC <em>angle addition property</em>
60 + ∠BDC = 80 <em>substituted solved and given information</em>
∠BDC = 20 <em>subtraction property</em>
(ii) SORRY but I'm not sure how to find ∠BCD. If ∠ADC = ∠ABC, then ∠DBC = 30. We already calculated ∠BDC = 20, which means that ∠BCD = 130
(iii)
∠BCA = ∠ADB <em>given as a hint</em>
∠BCA = 60 <em>substituted ∠ADB that was solved in part (i)</em>
Answer: (i) = 20, (ii) = 130?, (iii) = 60
Answer:
+ 121
Step-by-step explanation:
A function f(x) divided by (x - h) has remainder f(h)
Given
f(x) = 2 - x - 5 divided by (x - 2) then remainder is f(2), thus
f(2) = 2 - 2 - 5 = 2(64) - 7 = 128 - 7 = 121
