9c=45 Divide both sides by 9, therefore:
c=5
F = (9c/5) + 32
45 = 30 + m Subtract 30 from both sides: 15 = m
correct anser is C ; y=-45
To evaluate the expression (9c - 3) when (c = 10), substitute 10 for (c): [9(10) - 3 = 90 - 3 = 87.] So, when (c = 10), the expression (9c - 3) equals 87.
y = 2 (Divide each side of the equation by -45)
You need to get n alone.9n=45 → Divide by 9n=45/9n=5
3a + 9 =3X(a + 3)
F = (9c/5) + 32
45 = 30 + m Subtract 30 from both sides: 15 = m
45+4 = 49 49/7=7 7*7=49-4=45 so x=7

90 * * * * * No. 45 - 45 equals 45 is a false statement.
To solve the equation -9n = 45, you first need to isolate the variable n. To do this, divide both sides of the equation by -9 to get n = 45 / -9. Simplifying further, n = -5. Therefore, the solution to the equation -9n = 45 is n = -5.

in the question 7-5u=-43, the answer to u is -45, because 7-5=2, 2x-45=-43. so u=-43.
