100 because they form a supplementary angle which means they add to 180
5(n-4)=(4n-12)
First: Distribute 5 into n and -4.
5(n-4)=(5n)+(5*-4)= 5n-20.
Second: Subtract 4n from both sides to eliminate the variable from the right side of the equation.
(5n-20)=(4n-12)
n-20=-12
Next: Add 20 to both sides to eliminate the constant from the left side of the equation.
n-20=-12
n=8
The unknown number is 8.
awnser 4x^2 + 20xy + 25y^2
Answer:
a. y = 3 × 0 + 15
y= 0+15
y= 15
Step-by-step explanation:
Subtitute the variables into the place they are denoted with and solve it
And the place where the equation will cross the y axis is just the last numbers i.e. 15 and 3z which is 6
Answer:
4 tickets = £111.52
Step-by-step explanation:
