Answer:
The numbers are 18 and 91
Step-by-step explanation:
You can translate the information to two equations:
<em>a value 5 times a smaller number is 1 less than a larger number</em>
5a = b - 1
<em>their difference is 73</em>
b - a = 73
Then you should merge one equation into the other, thereby eliminating one variable. You can do this any way you want. I choose to rewrite the first equation as:
b = 5a + 1
Now I can write 5a+1 in the second equation at the place where b was:
5a + 1 - a = 73
It is now an equation with only one variable, solve by simplifying
4a = 72
a = 18
Now b can be found using b = 5a + 1
b = 91
Answer:
80
Step-by-step explanation:
you do 3+2 first which is 5. And then you do 4^2 which is 16. when you multiply them you get 80
I think it would be 5,720, because if you figure every year the population grows 260, then 2600x2 would be doubled then add the 2 years missing so add 260+260. It would equal 5,720.
X + x + x + x + 2 + 2 = 24 Length: (x + 2) = 5 + 2 = 7 inches
4x + 4 = 24 Width: (x) = 5 inches
-4 -4
4x = 20
divide by 4 on both sides
x = 5
Answer:

Step-by-step explanation:
<u>Newton's law of cooling states </u>
"<em>that the temperature of a body changes at a rate proportional to the difference in temperature between the body and its surroundings"</em>
Newton's Law of Cooling is given by the formula

Where
F(
t
) is the temperature of the object at a given time t
T
s
is the surrounding temperature
T
0 is the initial temperature of the object
k is the constant
Given k=0.2
Hence the expression is
