Find two consecutive numbers if square root of the bigger number is 5 less than the smaller number
Using a system of equations, it is found that the two consecutive numbers can be 8 and 9, or 3 and 4.
What is a system of equations?A system of equations is when two or more variables are related, and equations are built to find the values of each variable.
In this problem, the numbers are consecutive, hence they are n(smaller number) and n+1(larger number).
The square root of the bigger number is 5 less than the smaller number, hence:
[tex]\sqrt{n+1} = n - 5[/tex]
[tex](\sqrt{n+1})^2 = (n - 5)^2[/tex]
[tex]n^2 - 10n + 25 = n + 1[/tex]
[tex]n^2 - 11n + 24 = 0[/tex]
[tex](n - 8)(n - 3)[/tex]
The solutions are n = 8 and n = 3. Hence, the consecutive numbers can be 8 and 9, or 3 and 4.

There is a ratio of 2 cats to every 3 dogs, if this rate continues how many dogs are there if there are 22 cats?
Answer:
33 dogs
Step-by-step explanation:
By taking the 22 cats and dividing it by the ratio. Then multiply that quotient by the ratio of dogs.
Thus:
22/2 = 11
11*3 = 33
There will be 33 dogs.
Hope This Helps :)
Answer: 33
Step-by-step explanation:
2cats = 3dogs
22cats = x
Cross multiply
2x = 3×22
2x = 66
x = 66/2
x = 33

Julie says that the most amount of time spent on homwork is 1 1/2 times the least amount of time spent on homwork who is correct explain
Required Data :
1 3/4, 2 1/2, 2, 2 3/4, 1, 1 3/4, 1 1/4, 3, 3 1/4, 3 3/4, 2, 2
Answer:
Julie is Incorrect
Step-by-step explanation:
Given the data:
1 3/4, 2 1/2, 2, 2 3/4, 1, 1 3/4, 1 1/4, 3, 3 1/4, 3 3/4, 2, 2
Arrangement in ascending order :
1, 1 1/4, 1 3/4, 1 3/4, 2, 2, 2, 2 1/2, 2 3/4, 3, 3 1/4, 3 3/4.
The least amount of time spent is : 1
The most amount of time spent is : 3 3/4
From Julie's assertion, that the most amount of time spent is equal to 1 1/2 the least amount of time spent.
Most amount of time = 1 1/2 * least amount of time
3 3/4 = 1 * 1 1/2
15/4 = 3/2
However, 15/4 ≠ 3/2
Hence, Julie is incorrect

F(x)=x^2+14 and g(x)=x−8
Find (f+g)(−1)
Answer:
Step-by-step explanation:
Disclaimer all solutions need to be verified by the student for accuracy in typos, algebra and calculations.
f(x) = x² + 14 g(x) = x - 2 -1 ? I think it means evaluate when x = -1
Find (f(x) + g(x)) when x = -1
(f(x) + g(x)) = [ ( x² + 14) + (x - 2)] insert f(x) and g(x)
= [ x² + x + 14 - 2] add like the term
(f(x) + g(x)) = x² + x + 12
(f(-1) + g(-1)) = (-1)² + (-1) + 12 evaluate at x = -1
= 1 - 1 + 12
= 12

Answer:
A. x=5,y=6
Step-by-step explanation:
Add y to both sides of the equation.
x=−1+y
x−3y=−13
Replace all occurrences of x with −1+y in each equation.
−1−2y=−13
x=−1+y
Solve for y in the first equation.
y=6
x=−1+y
Replace all occurrences of y with 6 in each equation.
x=5
y=6
The solution to the system is the complete set of ordered pairs that are valid solutions.
(5,6)
The result can be shown in multiple forms. Equation Form: x=5,y=6
Bilal and Charlie have some sweets. Bilal has 4 times as many sweets as Charlie. Bilal gives Charlie 15 of his sweets and now they have the same amount. How many sweets do they have altogether?
Answer:
50
Step-by-step explanation:
The computation of the number of sweets they do have altogether is as follows:
Let us assume Charlie sweets be x
So bilal sweets is 4x
Now Bilal gives Charlie 15 of his sweets due to which they must have the same amount
4x - 15 = x + 15
4x -x = 15 + 15
3x = 30
x = 10 = Charlie sweets
Bilal sweets = 4x = 4(10) = 40
So the total no of sweets held by them is 50
I NEED THIS QUICK! Daniella has 130 baseball cards. She buys 10 new cards to add to her collection every month. Which arithmetic sequence describes the number of cards in her collection?
A. a1=10;an=an−1+130
B. a1=10;an=an+1+130
C. a1=130;an=an−1+10
D. a1=130;an=an+1+10
Answer:
Step-by-step explanation:
The answer is the third one.
She starts with 130
a1 = 130
She adds 10 every month.
So you take the number she had last month (represented by a_n-1) and adds 10.
Answer
a1 = 130
an = an_1 + 10

Step-by-step explanation:
Answer: a) see the graph below
b) n > 24/5 or 4.8
Step-by-step explanation:
a) see the graph below.
-2 is smaller and equal to x, so the point is close circle; and 3 is only greater than x, so it only has open circle, and the line was between the range from -2 to 3.
b) 5n + 3 >27
5n > 24 [Subtradt 3 from both side]
n > 24/5 or 4.8
2). Write an equation and solve. You will not be given credit for your answer if you do not include your equation! This month's cell phone bill was for $15.27 more than last month's cell phone bill. If this month's phone bill is for $72.50, how much was last month's cell phone bill?
Answer:
Equation is: x+15.27 = 72.50Solution to that equation: x = 57.23Interpretation: Last month's phone bill was $57.23========================================================
Explanation:
We'll make x the value of last month's phone bill. So if lets say x = 50, this means that last month's phone bill was $50. We don't know yet if x = 50 is the actual solution or not.
We're told that "This month's cell phone bill was for $15.27 more than last month's cell phone bill". This means this month's bill, in terms of x, is x+15.27 dollars. Whatever x is, we add 15.27 onto it getting this month's bill. This works because x is really a placeholder for a number.
Going back to x = 50, that would mean this months bill is x+15.27 = 50+15.27 = 65.27 dollars. We can see that we don't reach 72.50 that we're told the current months bill actually is. Since we don't have a match, this means x = 50 is too small. We can guess and check our way to hopefully land on the answer. However, using algebra is the most efficient method.
----------
The equation we need to solve is: x+15.27 = 72.50
This is because x+15.27 represents this month's bill and so does the 72.50, as your teacher gave in the instructions.
To solve this equation, we'll undo the "plus 15.27" to isolate x fully. The opposite of addition is subtraction. We'll subtract 15.27 from both sides
x+15.27 = 72.50
x+15.27-15.27 = 72.50-15.27
x = 57.23
Last month's phone bill was $57.23
As a check, adding 15.27 onto last month's bill should get us to 72.50
x+15.27 = 57.23+15.27 = 72.50
It works out, so we've confirmed the answer.
