Mary sees 40 elephants and 15 baby elephants at the zoo. What is the ratio of elephants to baby elephants?
Answer:
8:3
Step-by-step explanation:
You divide them both by 5.
Answer:
40:15 = 8:3
Step-by-step explanation:
This is the answer because:
1) Since there are 40 elephants and 15 baby elephants, the answer would be 40:15, but we want to simplify the ratio. In order to simplify the ratio, just divide each number by 5:
40 ÷ 5 = 8
15 ÷ 5 = 3
8:3
Therefore, the answer is 8:3.
Hope this helps! :D
I am having a hard time with simultaneous equations specifically the elimination method, i want to know when do we subtract and when do we add, so if u know how its done plz help im confused
Example :
3x-2y =7
4x+y = 13
Plz solve it too-
Answer:
The solution to these two equations is (3, 1)
Step-by-step explanation:
So for the elimination method, we are basically multiply each equation by a factor that would allow us to cancel them out..
We could rewrite the equations as the following to make the elimination method easier:
-2y + 3x = 7
y + 4x = 13
We could multiply the second equation by positive 2 in order to cancel out the y from the first equation when we add.
-2y + 3x = 7
2y + 8x = 26 ---> Now we have 11x = 33, when we simplify, we have x = 3.
Now to find our y value in order to find the solution, we would just plug in our x value and solve for y. **We can use either equation to find the answer for this...
-2y + 3x =7.
-2y + 3(3) = 7
-2y + 9 = 7
-2y = -2
y = 1.
We can double check our answer by plugging in both x and y values into the second equation.
4(3) + 1 = 13.
12 + 1 = 13, so we are correct.
The solution to these two equations is (3, 1)

Answer:
-3 or decreasing by 3
Step-by-step explanation:
To find the average change, you only care about the first and last point which would be (3,17) and (8,2)
the overall change during that time is 2-17=-15 (for the f(x) side )
the overall change during that time is 8-3=5(for the x side)
all we have to do is -15/5=-3
therefore the average rate of change is -3

Answer:
x = 10
Step-by-step explanation:
x-sqrt(2x+5) = 5
2x+5 = 25-10x+x^2
x = 10
Hope this helped!
Answer:
x = 5
Step-by-step explanation:
x - 5 = [tex]\sqrt{2x+5}[/tex] ( x > 5)
(x - 5)² = ( [tex]\sqrt{2x+5}[/tex] )²
x² - 10x + 25 = 2x + 5
x² - 12x + 20 = 0
(x - 10)(x - 2) = 0
[tex]x_{1}[/tex] = 10
[tex]x_{2}[/tex] = 2 strange root, does not satisfy the condition x > 5 ( 2 - [tex]\sqrt{2*2+5}[/tex] ≠ 5 )
10 - [tex]\sqrt{2*10+5}[/tex] = 5
10 - 5 = 5
5 = 5

8x⁹⁶ is the simplified form of the expression.
What is a polynomial expression?Polynomial is made up of two terms, namely Poly (meaning “many”) and Nominal (meaning “terms.”). A polynomial is an expression composed of variables, constants, and exponents, combined using mathematical operations such as addition, subtraction, multiplication, and division (No division operation by a variable). Based on the number of terms present in the expression, it is classified as monomial, binomial, and trinomial. For example P(x) = x2-5x+11
Given here, the expression as (256x²⁵⁶)^³/₈
=(256)^³/₈ × (x²⁵⁶)^³/₈
=(2⁸)^³/₈ × (x³²)^³
=2³ × x⁹⁶
Hence, the answer is 8x⁹⁶
