In linear equation, Total number of red blood cells in the body is 29 * 10¹¹ .
What in mathematics is a linear equation?
A linear equation is a first-order (linear) term plus a constant in the algebraic form y=mx+b, where m is the slope and b is the y-intercept.
Sometimes, the aforementioned is referred to as a "linear equation of two variables," where x and y are the variables.
Red blood per cubic millimeter = 5,800,000 = 5.8 * 10⁵
Red blood in 5 litres of blood = 5.8 * 10⁵ * 5 * 10⁵
= 29.0 * 10¹⁰
= 29 * 10¹⁰ * 10
= 29 * 10¹¹
Total number of red blood cells in the body is 29 * 10¹¹.

the triangle has a perimeter of 65 feet. what system of equation to use for the perimeter equals 65 feet? l= 1/3m, m, and n=l+m-15
Answer:
l = 10 feet
m = 30 feet
n = 25 feet
Total Perimeter = 65 feet
Step-by-step explanation:
The perimeter of a trianlge is the sum of its three sides, and in this case is equal to 65 feet.
65 feet = l + m + n
l + m + n = 65
We also know that:
l = (1/3)m, and
n = l+m-15
Substitute these definitions of l and n into the original equation:
l + m + n = 65
[(1/3)m] + m + [l+m-15] = 65
[(1/3)m] + m + [[(1/3)m]+m-15] = 65
Simplify:
(1/3)m + m + (1/3)m + m - 15 = 65
2m + (2/3)m = 80
(6/3)m + (2/3)m = 80
(8/3)m = 80
m = 80*(3/8)
m = (10)*(3)
m = 30 feet
Since l = (1/3)m, l = 10 feet
Since n = l+m-15, n = 10 + 30 - 15, or 25 feet
The three sides are
l: 10 feet
m: 30 feet
n: 25 feet
Total = 65 feet

What is the solution to the system of equations?
2x+6y=-28
x + 3y = -14
Because when two linear equations graph this very same line, a system of two linear simultaneous equations variables cannot be solved.
What in mathematics is a linear equation?A linear equation seems to be an algebraic equation of something like the form y=mx+b, where m is the slope as well as b is the y-intercept, and only a constant and an initial-order (linear) component are included. The variables in the preceding equation are y and x, and it is occasionally referred to as a "linear equation of two variables."
Briefing:2x+6y=-28 (i)
x + 3y = -14 (ii)
Subtract 3y from both sides of the equation(ii)
[tex]\begin{matrix}&x=-14-3y\\&2x+6y=-28\\\end{matrix}[/tex]
Replace all occurrences of x with -14-3y in each equation.
Replace all occurrences of x in 2x+6y=-28 with -14-3y.
[tex]\begin{matrix}&2(-14-3y)+6y=-28\\&x=-14-3y\\\end{matrix}[/tex]
Simplify the left side.
Simplify 2(-14-3y)+6y.
[tex]\begin{matrix}&\ -28=-28\\&x=-14-3y\\\end{matrix}[/tex]
Remove any equations from the system that are always true.

What is linear inequation?
Inequation shows the comparison between two algebraic expressions by connecting the two algebraic expressions by >,<, ≥, ≤
A one degree inequation is known as linear inequation.
Here,
One line passes through (0, 8) and (-1, 7)
Slope of the line = [tex]\frac{7-8}{-1-0}[/tex] = 1
Equation of line
y - 8 = 1(x - 0)
y - 8 = x
x - y = -8
Other line passes through (-4, 4) and (-3, 1)
Slope of the line = [tex]\frac{1-4}{-3-(-4)}[/tex] = -3
Equation of line
y - 4 = -3(x - (-4))
y - 4 = -3x - 12
3x + y = 4 - 12
3x + y = -8
Now the lines are solid lines
So equality is maintained
(0, 0) is inside the shaded region
So the system of linear inequation represented by the graph is

What is a Parallelogram?
A quadrilateral having two sets of parallel sides is referred to as a parallelogram. In a parallelogram, the opposing sides are of equal length, and the opposing angles are of equal size. Additionally, the interior angles that are additional to the transversal on the same side. 360 degrees is the sum of all interior angles.
A parallelepiped is a three-dimensional shape with parallelogram-shaped faces. The base (one of the parallel sides) and height (the distance from top to bottom) of the parallelogram determine its area. A parallelogram's perimeter is determined by the lengths of its four sides.
As it is a parallelogram so, the opposite sides of the parallelogram are equal so NM=OL and ON=LM ,
according to the question ;-
NM = x+5
OL=2x+3

A motorcycle covers 315 km distance with 7 liters of petrol.
i)how many kilometres does it cover with 12 liters of petrol in the same mileage?
ii)how much petrol is needed to cover 270 km in the same mileage?
Step-by-step explanation:
225 km travels in =25 ltr
1 km travel = 225 25
540 km will require = 22525 ×540=60 L
Was this answer helpful?
Answer:
1) 540 km
2) 6 liters of petrol
Step-by-step explanation:
To answer the two questions, it is easiest to fist find the relationship between kilometers (km) and liters of petrol. Since 7 liters (L) results in 315 km, we can find the km/liter petrol conversion factor (converts liters of petrol to km):
(315 km)/(7 liters) = 45 km/L
1) 12 liters times the conversion factor will tell us how many km the motorcycle will travel"
(12 liters)*(45 km/liter) = 540 km [Note that the liters unit cancles, leaving only km]
2) To find the liters of petrol to travel 270 km, we can use the same conversion factor, but now we need to divide to get the units we want, which is km:
(270 km)/(45 km/l) = 6 liters [Note that km cancels and l moves to the top, leaving liters as the only unit.

In a fish tank, 4/9 of the fish have a red stripe on them. If 12 of the fish have red stripes, how many total fish are in the tank?
Answer: If 4/9 of the fish have a red stripe, we can determine the total number of fish in the tank by dividing the number of fish with red stripes by the fraction of fish with red stripes. This gives us 12 / (4/9) = 12 * (9/4) = 27 fish. So, there are 27 fish in the tank.
[tex] \frac{4}{9} x = 12[/tex]
[tex]x = 12 \times \frac{9}{4} [/tex]
[tex]12 \times 9 = 108[/tex]
[tex]4 \times 1 = 4[/tex]

The equation for the relationship between the regular price (r) and the neighbor's price (n) will be r - n = 250.
What are equations?A mathematical expression with an equals sign is referred to as an equation.
Algebra is widely used in equations.
When performing calculations but unsure of the precise number, algebra is used.
Linear equations: Any equation that can be expressed as ax + by + c = 0, where a, b, and c are all real numbers and a and b are not equal to zero.
In light of the posed query.
Khalid keeps bees and sells honey from them.
Additionally, n stands for the neighbor's honey price in dollars and r stands for the ordinary honey price in dollars.
We can determine the discount from the provided information.
7 - 4.50 = 2.50
8 - 5.50 = 2.50
10 - 7.50 = 2.50
12 - 9.50 = 2.50
Khalid gives his neighbor $2.50.
The equation for the link between the regular price r and the neighbor's price n will therefore be: r - n = 250
Therefore, the equation for the relationship between the regular price (r) and the neighbor's price (n) will be r - n = 250.

Rewriting 8 as 2^3
2^p x 2^3^q = 2^n
Using the rule a^b^c = a^(b*c)
2^p x 2^3q = 2^n
Using the rule a^b * a^c = a^(b+c)
2 ^(p+3q) = 2^n
