Answer:
30
Step-by-step explanation:
s_{n}=\frac{a+l}{2}=n
first term=a
last term=l
number of terms=n
1485=\frac{6+93}{2}n
99 n=1485×2=2970
n=2970/99=270/9=30
number of terms=30
Step-by-step explanation:
3.5 more than the quotient of h and 5 is w
Solution,
Let the number be x, then

Answer:
y₂ = 3
Step-by-step explanation:
Calculate the slope m using the slope formula and equate to - 
m = 
with (x₁, y₁ ) = (7, - 6) and (x₂, y₂ ) = (- 5, y₂ )
m =
, that is
= -
( cross- multiply )
4(y₂ + 6) = 36 ( divide both sides by 4 )
y₂ + 6 = 9 ( subtract 6 from both sides )
y₂ = 3
The rate of this would be 11 sit ups because 55 divided by 5 would give you the answer 11
