To solve for r, you can multiply both sides of the equation by 7 to isolate r. This gives you r = 1400 * 7, which simplifies to r = 9800.
15 and 24, respectively.
Answers: There are none Explanation: It's gibberish.
12 = r/3 + 16
In these types of questions, you have to try to isolate the unknown variable.14 = 2 + r - 21.Remember whenever you move ANYTHING over the equals sign, you have to make its sign opposite. Since the r is positive, and we are moving it over the equals sign we have to make it a negative sign. When we move the 14 over, it is currently positive so we make it into a negative.-r = -14 + 2 - 21-r = -12 - 21-r = -43(Eliminate the negative sign)r = 43.
if r=5z and 15z =3 then r=10y
