Answer:
196
Step-by-step explanation:
1+2+3+4+......+25+26+27 = (1+27) + (3+25) + (5+23)+(7+21) + (9+19) + (11+17) + (13+15)
= 28 x 7 = 196
It's like area of trapezoid of bases: 1, 27 and height of 14
Answer: The answer is -19.
Step-by-step explanation: We are given to write the numerical coefficient of -9x.
The given expression is a monomial with unknown variable 'x'.
We know that a numerical coefficient of a monomial is a constant multiplied to the variable(s). For example, in the term -5xy, the unknown variables are 'x' and 'y' and the numerical coefficient is -5.
Therefore, in -9x, the unknown variable is 'x' and the numerical coefficient is -9.
Thus, the answer is -9.
Answer:
The length of the page inside the margins=8 3/4 inches
Step-by-step explanation:
The total length of the year book can be expressed as;
L=l1+l2+l3
where;
L=Total length of yearbook
l1=top margin length
l2=inside margin length
l3=bottom margin length
In our case;
L=10 inches
l1=1/2 inches
l2=unknown
l3=3/4 inches
replacing;
10=(1/2)+l2+(3/4)
(1/2)+(3/4)+l2=10
(5/4)+l2=10
l2=(10)-(5/4)
l2=8 3/4 inches
The length of the page inside the margins=8 3/4 inches
