Hello!
To solve algebraic equations, we need to use SADMEP. SADMEP acts like PEMDAS and is subtract, addition, division, multiplication, exponents and parentheses. If there are no variables, it is a regular equation, and can be simplified using PEMDAS.
(a) 4 + 2(-1) = 10 + 2 (multiply)
4 + -2 = 10 + 2 (add)
2 = 12
This equation has no solutions because -2 is not equal to 12.
(b) 30 = 10 + -1(6 + 10) (simplify)
30 = 10 + -1(16) (multiply)
30 = 10 + -16 (add)
30 = -6
This equation has no solutions because 30 is not equal to -6.
(c) 8x = 4x + 4x + 10(x - x) (simplify alike terms)
8x = 8x + 10(0) (multiply)
8x = 8x
This equation has an infinite number of solutions because another number substitute into x will result in the same solution on both sides of the equation.
<u>Final answers</u>:
- No solution (-2 ≠ 12)
- No solution (30 ≠ -6)
- Infinite number of solutions (8x = 8x -- resulting in same quotient)
Answer:
614.5

Hope this helps!
Use the Pythagorean theorem to solve this problem. So, 81+x^2=1681. ( Pythagorean theorem: a^2+b^2=c^2). x^2=1600. x=40.
The function y = 2.5x + 500 represents the total number of miles if the motor car race is 500 miles long, option (d) is correct.
<h3>What is a function?</h3>
It is defined as a special type of relationship, and they have a predefined domain and range according to the function every value in the domain is related to exactly one value in the range.
We have:
y represents the number of miles a motor car has left to go in the race
x represents the number of laps completed by the motor car
The total number of miles if we consider only circular speedways = 2.5x
The total number of miles:
y = 2.5x + 500 (because 500 is the constant)
Thus, the function y = 2.5x + 500 represents the total number of miles if the motor car race is 500 miles long option (d) is correct.
