Step-by-step explanation:
y = k * (3x - 5)
Where,
k = constant of proportionality
y = 33 when x = 5
y = k * (3x - 5)
33 = k * (3 * 5 - 5)
33 = k * (15 - 5)
33 = 15k - 5k
33 = 10k
k = 33/10
k = 3.3
a) y when x = 2
y = k * (3x - 5)
y = 3.3(3 * 2 - 5)
= 3.3(6 - 5)
= 3.3(1)
y = 3.3
b) x when y = 15
y = k * (3x - 5)
15 = 3.3(3x - 5)
15 = 9.9x - 16.5
15 + 16.5 = 9.9x
31.5 = 9.9x
x = 31.5/9.9
x = 3.18
Answer:
112°
Step-by-step explanation:
A pentagon has a total measure of 540°.
540-(102+103+112+111)=112
Answer:
10 meters
Step-by-step explanation:
The area of a triangle can be found by the equation: a=(bh)/2
The height of this triangle can be represented by the variable: (b - 4)
The base: b
The area: 30
Simply plug in these values and solve for b.
