Answer:
62 and 64
Step-by-step explanation:
Let x be the first number
Let y be the 2nd number
Given,
x + 2 = y (Consecutive even numbers)
x - y = -2 (rearranged) - Equation 1
x + y = 126 - Equation 2
Now we can solve for x and y to find the 2 numbers by using substitution method in solving simultaneous equations.
x = y-2 (rearranged equation 1)
Now we substitute equation 1 into equation 2.
y - 2 + y = 126
2y - 2 = 126
2y = 126 + 2
2y = 128
y = 128 / 2
= 64
Now we will substitute y into equation 1.
x - 64 = -2
x = -2 + 64
= 62
Therefore the 2 numbers are 62 and 64.
Answer:
since X would be equal to 9, x + 2 would be equal to 11
Johnathan will need to paint 1,962.5 square feet.
d = 50^r = 25 A = 2
A = (25)2
A = (3.14)(625) A = 1,962.5
Answer: $ 3045.48
Step-by-step explanation:
The exponential decay equation with rate of growth r in time period t is given by :-
, where A is the initial amount
Given : The rate of decay of population every year : 15% =0.15
The initial value = $9500
Then , the exponential growth equation in time period t is given by :-
After t= 7 years
The value of the sailboat will be :-
Hence, the value of the sailboat after 7 years= $3045.48.
