Answer:
x = 117°
Step-by-step explanation:
x and 63° are "Same Side Exterior Angles". These angles are supplementary.
Hence: x + 63 = 180
x = 180 - 63
x = 117°
Answer:
7m
Step-by-step explanation:
Given
- 9(- 5k + 3m) + 9m - 5(- 5m + 9k) ← distribute both parenthesis
= 45k - 27m + 9m + 25m - 45k ← collect like terms
= 7m
So 4/5 times "something" = 32.
That means that something = 32 / (4/5) = 40.
To turn this multiplication around, it helps to think about 2 * 3 = 6, how would you write 3 = ?. You quickly :"see" that it should be 3=6/2.
Answer:
y = 18.48
Step-by-step explanation:
y = kx where 'k' is the constant of variation
8.4 = 3.5k
k = 8.4/3.5 or 2.4
y = 2.4(7.7)
y = 18.48
