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

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]
[tex]x = \frac{108}{4} [/tex]

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

Transitive-According to the transitive property, "all the quantities are equal to each other if two quantities are equal to the third quantity."
Symmetric-Actually quite straightforward, equality has the symmetric property. According to this property, if a = b, then b must also be a. In other words, even if two equations' sides are switched, the.
Reflexive - It is said that a number is always equal to itself because of the reflexive property of equality. The equality's reflexive quality. If a is a number, then. a = a. a=a.

It is different from simple interest, where interest is not added to the principal while calculating the interest during the next period. In Mathematics, compound interest is usually denoted by C.I.
The formula is often given as;
