Answer: 23 years
Step-by-step explanation:
From the question, we are informed that the length of an island is decreasing a rate of 16 inches per year. The number of years that it will take for the change in length of the island to be -364 inches would be gotten by dividing 364 by the rate of decrease every year which is 16 inches. Therefore, this would be:
= 364 / 16
= 22.75 years
= 23 years approximately
What is the difference between a system of equations and a system of inequalities?
Expressions can be expressed as equations or as inequalities.
The difference is that the variables in a system of equation have one solution each, while in a system of inequalities, the variables have a range of values.
Let the system of equation be:
[tex]\mathbf{ax + by = c}[/tex]
[tex]\mathbf{dx + ey = f}[/tex]
Let the system of inequality be:
[tex]\mathbf{ax + by < c}[/tex]
[tex]\mathbf{dx + ey > f}[/tex]
Both systems can be solved using the same method, such as: graphs, substitution and elimination.
However, the difference is that:
In a system of equation, the variables can have one solution each, while in a system of inequalities, the variables have a range of values.

help please, 25 points! pythagorean thereom
Answer:
the pythagorean thereom is a^2 + b^2 = c^2
Step-by-step explanation:
to find the length of the hypotenuse use a^2 + b^2 = c^2 or b^2 + a^2 = c^2
but in order to find the length of the legs use c^2 - a^2 = b^2 or
c^2 - b^2 = a^2

If you were going to solve -3(x + 5) = 27, what is the first step that you would do? Why did you start there?
Answer:
Step-by-step explanation:
Multiply -3 for x and for 5
-3x-15=27
When you have this type of equation the first thing you do is take off the parentesis
Then you pass the 15 to the other side and you get -3x= 27 +15 . After that you divide that for -3 and you get the x . In this case x= -14

Jennifer purchased for 2$ and p pounds of sliced turkey at 5$ per pound for a total of $13.25. Which equation represents jennifer's purchase from the grocery store?
Answer:
$2 + $5p = $13.25
Step-by-step explanation:
Given that:
Initial purchase = $2
Pound of sliced turkey = p
Cost per pound of sliced turkey = 5$
Total amount spent = $13.25
Jennifers purchase from grocery store :
Initial purchase + (pound of sliced turkey * cost or pound) = total amount spent
$2 + $5p = $13.25

Wesley wants to have at least $50 to spend each day of his 7-day vacation. He plans to save $30 each month for 12 months. Which of the following shows that Wesley will save enough money for his vacation? Choose all that apply.
Answer:
i cant choose any that applies to this question because there is no picture added to it and there are no choices to choose from. If i were to solve it though, it would be; yes, he will save enough money for his vacation.
Step-by-step explanation:
I know he would have enough--and in this case more than enough, because since he's planning to save $30 for a whole year just for $50, when he could simply make $60--which is in fact more than needed for his goal-- in just 2 months. If he were to stick with his plan though, he'd make $360. I got that by multiplying 30 by 12.

Answer:
a = 2w/c/15
Step-by-step explanation:
14a = ac + 2w

ac + 14a = -2w
14a + a = -2w/c
15a = 2w/c
a = 2w/c/15

5x-3 =2x+15
Someone pls help for geometry
Answer:
x = 6
Step-by-step explanation:
5x-3 = 2x+15
i) move 2x to the left-hand side and change its sign5x-2x-3 = 15
ii) move -3 to the right-hand side and change its sign5x-2x = 15+3
iii) collect like terms3x = 15+3
iv) add the numbers3x = 18
v) divide both sides of the equation by 3[tex] \frac{3x}{3} = \frac{18}{ 3} [/tex]
[tex]x = 6[/tex]
The length of the two legs of a right triangle are 18 cm and 24 cm.
What is the length of the hypotenuse of the triangle?
O A. 30 cm
OB. 36 cm
OC. 42 cm
D. 48 cm
Answer: 30 cm
Step-by-step explanation: Take note that ^2 means to the second power.
a^2 + b^2 = c^2 (hypotenuse)
18^2 + 24^2 = c^2
324 + 576 = c^2
900 = c^2
To find the length of c you have to find teh square root of 900.
√c^2 = √900
c = 30
The length of the hypotenuse is 30 cm!
