Answer:
1800 is the original cost
Step-by-step explanation:
cost + 11% cost = 1998
Factor out the cost
cost *( 1+11%) = 1998
cost ( 1.11) = 1998
Divide each side by 1.11
cost = 1998/1.11
cost =1800
15)
4(a+b) + 12
= 4a + 4b + 12
= 4(a +b + 3)
answer is
b) 4(a +b + 3)
16)
x - 4(2x + 2)
= x - 8x - 8
= -7x - 8
answer
-7x - 8
Answer:
H(11)=101
Step-by-step explanation:
The function we have is:
and we need to find the value of
this is evaluating the function 
when the value of t is 
So, first we substitute in H(t):
we solve the expression:
the answer is that when , the function has the value 
There are 90 two digit numbers
