Answer:
We have 6 flamy and 10 Elephants
Step-by-step explanation:
A local zoo has flamingos and elephants in one exhibit.
Flamingos have 2 legs
Elephants have 4 legs
Let the number of
Flamingos = x
Elephants = y
There are 16 animals in the exhibit
= x + y = 16..... Equation 1
x = 16 - y
The animals have a risk of 52 legs.
2 × x + 4 × y = 52
2x + 4y = 52..... Equation 2
We substitute 16 - y for x in Equation 2
2(16 - y) + 4y = 52
32 - 2y + 4y = 52
- 2y + 4y = 52 - 32
2y = 20
y = 20/2
y = 10
Solving for x
x = 16 - y
x = 16 - 10
x = 6
Hence, we have
Flamingos = x = 6 flamingos
Elephants = y = 10 Elephants

adam can read 4 pages in 10 minutes. if adam reads at a constant rate, wich equation can be used to model the relationship between the number of pages he can read, p in t minutes?
Answer:
p=2.5t
Step-by-step explanation:
p stands for pages
2.5 is how long it takes him to read 1 page
t is the time
the reason why the t is next to 2.5 is so when you replace t with the actual time, you would multiply it by 2.5 to get how many pages he read in any amount of time

0.222
2.22
22.2.
Answer:
the volume at 606k is 2.22....the third one
Step-by-step explanation:
v1=1.00 t1=273 v2=? t2=606
v1/t1=v2/t2
1.00/273=v2/606
1.00×606=273v2
606=273v2
606/273=v2
2.21 L=v2

Answer:
y > 3.0083
Step-by-step explanation:
6(2y-4) +2.6 >14.7
=6 ×2y +6(-4) +2.6 >14.7
=12y - 24 + 2.6> 14.7
And then collect like terms
12y > 14.7 +24 -2.6
12y > 38.7 - 2.6
12y > 36.1
12. 12
y > 3.0083

Which of the following shapes are rectangles ? Please choose 2 correct answers !!!!!!!!!!!!!! Will mark Brianliest !!!!!!!!!!!!!!
Answer:
Hello there! Your answer would be D and A
Step-by-step explanation:
I cant see A but as I go through all the others I get A. You know that a rectangle has 4 sides like a quad. but each of the opposite sides has to be equal. So you can see that D is without needing to look closer. It gets harder after that. We know that C is not one because none of the sides are even. Now there is B and A if you turn your computer/paper you will see that B is a square. So because of that, I think that A is a rectangle. :]
The shapes that present the rectangle will be B and D.
What is a quadrilateral?The quadrilateral has four sides and four angles. The sum of internal angles is 360 degrees.
If the opposite sides of the quadrilateral are parallel then the quadrilateral is known as a parallelogram.
And if all the angles of the parallelogram will be equal. Then the parallelogram will be known as a rectangle.
It is a polygon with four sides. The total interior angle is 360 degrees. A rectangle's opposite sides are parallel and equal, and each angle is 90 degrees. Its diagonals are all the same length and intersect in the center.
The shapes that present the rectangle will be B and D.

Both inequalities use the division property to isolate the variable, y. When you divide by a negative number, like –7, you must reverse the direction of the inequality sign. When you divide by a positive number, like 7, the inequality sign stays the same. The solution to the first inequality is y > -23, and the solution to the second inequality is y <>

The constant of the equation, height = constant/width, is calculated as: B. 0.5.
What is a Constant of an Equation?The constant is a value that doesn't changes as both variables in the relationship changes.
Given that, height = constant/width, therefore:
Constant = (height)(width)
Using any of the points, say, (1, 0.5):
Constant = (0.5)(1)
Constant = 0.5
