2s^3 – 4r^1 r = 1 and s = 5
explian how to solve it
there's nothing to "solve"
Just evaluate the expression using the values given. Wherever you see an r, replace it with a 1. Same for s, using 5.
However, first you have to know what it means:
2(s^3) - 4(r^1)
Now just plug and chug:
2(5^3) - 4(1^1)
2(125) - 4(1)
250 - 4
246
To solve the equation, you need to substitute the given value of s into the equation and simplify it to find the value of r.
1. Start with the equation: 2s^3 - 4r^1 r = 1
2. Substitute the given value of s into the equation: 2(5)^3 - 4r^1 r = 1
3. Simplify the equation: 2(125) - 4r = 1
4. Multiply: 250 - 4r = 1
5. Rearrange the equation by subtracting 250 from both sides: -4r = 1 - 250
6. Simplify: -4r = -249
7. Divide both sides of the equation by -4: r = (-249) / (-4)
8. Calculate the division: r = 62.25
Therefore, the solution to the equation is r = 62.25.
