The sum of 3 consecutive odd integers is 87.Find the equation used to solve this problem and the three integers.

Answers

the first odd integer is x. The next odd integer will be x+2. and the next is x+4. Then we can say that (x)+(x+2)+(x+4)=87
working that out yields 3x+6=87
and thus 3x=81
and by consequence x=27

and thus our 3 odd integers are 27,29 and 31

Let be y - 2, y and y + 2 the 3 consecutives odd integers;
There sum is 3y, and, in the same time is 87 => y = 87/3 => y = 29 =>
y - 2 = 27; y + 2 = 31;
The 3 integers are : 27, 29, 31.

Answer:

g(x) = x² - 5

Step-by-step explanation:

The vertex form of a parabola is:

→ y = (x - a)² + b

where (a, b) is the vertex of the parabola.

From the graph, we can identify that the vertex has been shifted down 5 units, and it has not been shifted horizontally. Therefore, we can assign the following a and b values:

a = 0
b = -5

Now, we can plug these into the vertexformequation to get the equation of the function g(x):

y = (x - 0)² + (-5)

This simplifies to:

y = x² - 5

Use substitution to solve the sytem: 5x-3y=-20 and x=3y-16

Answers

$5x - 3y = -20$
$x = 3y - 16$

Plug in 'x' into the first equation:

$5 (3y - 16) - 3y = 20$
$15y - 80 - 3y = -20$
$12y = 60$
$y = 5$

Plug in 'y' into the second equation to get 'x':

$x = 3y - 16$
$x = 3(5) - 16$
To get $x = -1$

$y = 5$
$x = -1$

5(3y-16)-3y = -20
15y-80-3y = -20
12y = 60
y = 5

The density of water is 1000 kilograms per cubic meter and the density of ice is about 916 kilograms per cubic meter of 700 kilograms of water and 450 kilograms of ice is combined in a container what is the volume of the water

Answers

Final answer:

The volume of water can be calculated by dividing the mass of water by the density of water.

Explanation:

The question asks for the volume of water when 700 kilograms of water and 450 kilograms of ice are combined in a container. To find the volume of water, we need to subtract the volume of ice from the total volume. The density of water is 1000 kg/m³, so the volume of water can be calculated by dividing the mass of water (700 kg) by the density of water (1000 kg/m³).

Volume of water = Mass of water / Density of water

Volume of water = 700 kg / 1000 kg/m³

Volume of water = 0.7 m³

A metal washer is made by cutting out a circle 13.2 mm in diameter from a larger circle. To the nearest tenth, what is the area of the washer

Answers

The standard formula of area of the circle is (pi * r^2)
here r is radius.

So the radius of this washer is equal to 6.1 mm (13.2 / 2)
Therefore the area of the washer
pi * 6.1^2
116.9 mm^2
