Answer:
L(1-0.15)
L-(15/100)L
Step-by-step explanation:
we know that
100%-15%=85%
85%=85/100=0.85
so
The number of hours that Mateo spent at the beach last week is equal to the hours that landen spent at the beach (L) multiplied by 0.85
The linear equation that represent this situation is
0.85L
<u><em>Equivalent expressions are</em></u>
1) L(1-0.15)
Because
Applying distributive property
L(1-0.15)=L-0.15L
Combine like terms
L-0.15L=0.85L
2) L-(15/100)L
because
15/100=0.15
substitute
L-(15/100)L=L-(0.15)L=0.85L
Answer:
-1x - 3 or -x - 3
Step-by-step explanation:
1/5 (5x - 15) - 2x =
1x - 3 - 2x =
1x - 2x - 3 =
-1x - 3
Answer:
C is the correct answer
Step-by-step explanation:
A) 25-18 which equals 7
7 is NOT bigger than 8
B) 0.5x18= 9
7 is NOT bigger than 9
C) 18÷6=3
3 IS bigger than 2 so is correct
D) 18÷4= 4.5
4.5 is NOT bigger than 3
hope this helps!
Answer:
273 frogs.
Step-by-step explanation:
The equation of growth in the number of frogs N = 137(1.09)^t where t is the time in years.
The year 2022 is 8 years after 2014 so the prediction for N in 2022 is:
N = 137(1.09)^8 = 273.
The formula is a subscript n = 6^n
Where a1 is the first term and d is the common difference of the sequence
Thus, the first term is 6, second term 36, then 216.....
thus the sequence is, 6, 36, 216, .....................
Therefore, this is a geometric sequence with a common difference of 6
