Answer:
x = 10
Step-by-step explanation:
30/35 = (6x-6)/63
210x - 210 = 1890
210x = 2100
x = 10
A heptagon has 7 sides.
Sum of all interior angles = (7 - 2) x 180 = 900°
900 - 776 = 124°
Answer: The final angle must be 124°
Answer: The first graph.
This can be found by looking at the y-intercept and plugging in values for x.
17.46% of 126 is 22
Divide 22 by 126:
Change the decimal into a percentage by multiplying the decimal by 100:
Answer: x = -1 y = 4 I got my answer by solving for one variable in the first equation and then substituting what I got for that variable into the second equation in place of that aforementioned variable then solving for the last variable.
