Find <em>n</em> :
P = a + b + c
63 = n + (4n - 8) + (2n + 8)
63 = (n + 4n + 2n) + (-8 + 8)
63 = 7n
n = 63 ÷ 7
n = 9
Sides :
1.) n = <u>9</u>
2.) 4n - 8 = 4(9) - 8 = 36 - 8 = <u>2</u><u>8</u>
3.) 2n + 8 = 2(9) + 8 = 18 + 8 = <u>2</u><u>6</u>

Answer:
−5<c<1
Step-by-step explanation:
Let's solve your inequality step-by-step.
7<12+c<13
7<c+12<13(Simplify all parts of the inequality)
7+−12<c+12+−12<13+−12(Add -12 to all parts)
−5<c<1
Answer:
The fraction of the work that are drawings is
Step-by-step explanation:
we have that
100%=100/100=1
we know that
The sum of the fractions of the works must be equal to 1
Let
x -----> the fraction of the work that are drawings
so
Solve for x
Subtract 13/30 both sides
