Mathematics

mart [117]3 years ago

Answer:

The value of r is 4

Step-by-step explanation:

\frac{r}{4}  =  \frac{60}{120}

In order to find the value of r, you need to get rid of denorminator. By multiplying 4 to both sides:

(r/4)×4 = (60/120)×4

r = (1/2)×4

= 2

Answer:

r = 2

Step-by-step explanation:

Note that 60/120 reduces easily to 1/2.  Then we have:

r/4 = 1/2

Multiplying both sides by 4 removes the fractions, yielding r = 2

Which system of equations can you use to find the roots of the equation? x3 – 10x = x2 – 6 y = x3 – x2 + 10x + 6 y = 0 y = x3 –
Maslowich

Answer:

answer is:

y=x^{3}-10 x,y=x^{2}-6

Step-by-step explanation:

we are asked to find which system of equations can we use to find the roots of the equation:

x^{3}-10x=x^{2}-6

since the system of equation in last part is given as:

y=x^{3}-10 x,y=x^{2}-6

so, on equating both the equations i.e. on equating both the values of 'y' we get the desired equation as:

x^{3}-10x=x^{2}-6.
