Step-by-step explanation:
Answer:
x = 3
Step-by-step explanation:
The equation is,
16 = 5x+1
Subtract 1 from both sides,
16-1 = 5x
15 = 5x
Divide by 5,
x = 3
Step-by-step explanation:
4 + n + 7m
constants are just the numbers with no variables (letters)
so the constant is 4
coefficients are numbers multiplied by variables (letters)
so the coefficients are : 7 and 1
the error sarah made is forgetting the coefficient of n......because even if it is not written, n is the same as 1n....so basically, there is a coefficient for EVERY variable, even if its not written.
There are 10 pairs of sides that touch each other
Answer:
Step-by-step explanation:
Sum of external angles = 360
2x + 2x + x + 20 +x +40 = 360
6x + 60 = 360
6x = 360 - 60
6x = 300
x = 300/6
x = 50
