Answer:
- 
Step-by-step explanation: this equation works if you have two points

-3-4/2-(-3)=-7/5
To find the percentage of something, simply multiply the percentage (converted into a decimal) and the total. 60% = 0.6. 0.6*1.15 = 0.69.
The markup is $0.69.
To find the retail price, add the markup to the wholesale cost. 0.69+1.15= 1.84.
The retail price is $1.84.
Hope that helped you.
Answer: The area is 530 square units
Step-by-step explanation: The diameter of the circle has been given as 26. That makes the radius 13, that is;
Radius = diameter/2
Radius = 26/2
Radius = 13
The area of a circle is derived by the formula;
Area = pi x r^2
Where pi is 3.14 and r is 13,
Area = (3.14) x 13^2
Area = 3.14 x 169
Area = 530.66
Approximately to the nearest hundred of a square unit,
The area of the circle is 530 square units
Answer:
x+y=0 and 3x-2y=10
Step-by-step explanation
Let the numbers be x and y.
The sum of the two numbers is 0

Letting the smaller number be y and the
larger number be x:
twice the smaller number

Also, 3 times the larger number

Now ,twice the smaller number subtracted from 3 times the larger number is 10.

Therefore the equations are

and
