A zoologist is recording the loss of wolves in her state. She notes the number of wolves, w, in the state on January 1. One year later, there were 84 wolves in the state, which is 23 fewer wolves than were in the state a year earlier. What is the number of wolves in the state on January 1?
Which equation can be used to find the number of wolves in the state on January 1?
w + 23 = 84
w−23=84
w−84=−23
23−w=84
Answer:
w+23=84 is the answer for that problem because in order to find the answer u need to do the opposite of subtraction
Answer:
w - 23 = 84
Step-by-step explanation:
W is the amount of wolves they had in the state for the first year. If 84 wolves is 23 less than what they had originally you would be subtracting that amount to get 84.

Given:

To find:
The value of given expression in the form of [tex]b+c\sqrt{2}[/tex].
Solution:
We have,
[tex](4+\sqrt{2})(6-\sqrt{2})[/tex]
Using distributive property, we get
[tex]=4(6-\sqrt{2})+\sqrt{2}(6-\sqrt{2})[/tex]
[tex]=4(6)+4(-\sqrt{2})+\sqrt{2}(6)+\sqrt{2}(-\sqrt{2})[/tex]
[tex]=24-4\sqrt{2}+6\sqrt{2}-2[/tex]
On combining like terms, we get
[tex]=(24-2)+(6\sqrt{2}-4\sqrt{2})[/tex]
[tex]=22+2\sqrt{2}[/tex]
On comparing with [tex]b+c\sqrt{2}[/tex], we get
[tex]a=22,b=2[/tex]
Therefore, the required form is [tex]22+2\sqrt{2}[/tex].

Explain your answer
Thanks For the Help:)
Answer:
1.) z = -1
2.) z = -5
3.) t = 9
Step-by-step explanation:
z + (-7) = -8
=> add 7 to both sides
z = -1
13 = z + 18
=> subtract 18 from both sides
-5 = z
12 = t + 3
=> subtract 3 from both sides
9 = t
K is between J and L. JK = 3x – 5, and KL = 2x + 1. IfJL = 16, what is JK?
A. 7
B. 8
C. 9
D. 13
Answer:
If JL = 16, we will get JK = 7
Option A is correct option.
Step-by-step explanation:
We are given:
K is between J and L
JK = 3x – 5, and KL = 2x + 1.
IfJL = 16, what is JK
We know that K is between J and L it means it divides JL into JK and KL equally or we can say that adding JK and KL we can get JL
So, We can write:
[tex]JL = JK + KL\\16=3x-5+2x+1[/tex]
Solving the expression we can find first value of x and then value of JK
[tex]16=3x-5+2x+1\\16=5x-4\\16+4=5x\\20=5x\\x=\frac{20}{5}\\x=4[/tex]
So, we get x = 4
Now, put the value of x in JK=3x-5 to get value of JK
[tex]JK = 3x-5\\JK=3(4)-5\\JK = 12-5\\JK=7[/tex]
So, if JL = 16, we will get JK = 7
Option A is correct option.

Sharon kicks a ball from the ground into the air with an upward velocity of 64 feet per second. The function h = -16t2 + 64t models the height h, in feet, of the ball at time t, in seconds. When will the ball reach the ground again?
Step-by-step explanation:
h = 64t - 16t².
When the ball reaches the ground, h = 0.
Therefore 64t - 16t² = 0, 16t(4 - t) = 0, t = 0 or t = 4.
Therefore the ball reaches the ground 'again' at t = 4.

What is 149/15 as a mixed number?
Answer:
its an improper
mixed : 9 14/15
Step-by-step explanation:
its a mixed number if the number at the tops in the limit and there is a number at the side that represents whole number(s)
Answer:
the answer is 9 14/15
Step-by-step explanation:
Step 1 - Find Whole Number
Calculate out how many times the denominator goes into the numerator. To do that, divide 149 by 15 and keep only what is to the left of the decimal point:
149 / 15 = 9.9333 = 9
Step 2 - Find New Numerator
Multiply the answer from Step 1 by the denominator and deduct that from the original numerator.
149 - (15 x 9) = 14
Step 3 - Get Solution
Keep the original denominator and use the answers from Step 1 and Step 2 to get the answer. 149/15 as a mixed number is:
4. How do we divide polynomials using synthetic division?
Answer:
here
Step-by-step explanation:
Step 1 : set the denominator equal to zero to find the number to put in the division box. Next, make sure the numerator is written in descending order.
Step 2 : Once the problem is set up correctly, bring the leading coefficient (first number) straight down.
Step 3 : Multiply the number in the division box with the number you brought down and put the result in the next column.
Step 4 : Add the two numbers together and write the result in the bottom of the row.
Step 5 : Repeat steps 3 and 4 until you reach the end of the problem.
Step 6 : Write the final answer. The final answer is made up of the numbers in the bottom row with the last number being the remainder and the remainder must be written as a fraction.
A toy Jeep is 12 1/2 inches long, while an actual jeep measures 18 3/4feet long What is the value of the ratio of the length of the toy jeep to the length of the actual jeep? What does the ratio mean in this situation?
Answer:
1:18
Step-by-step explanation:
Given that,
Length of a toy jeep = 12 1/2 inches = 25/2 inches
Length of an actual jeep = 18 3/4 feet = 75/4 feet
1 foot = 12 inches
75/4 feet = 225 inches
We need to find the ratio of the length of the toy jeep to the length of the actual jeep.
[tex]R=\dfrac{\dfrac{25}{2}}{225}\\\\=\dfrac{1}{18}[/tex]
So, the required ratio is 1:18.
