1/3D + 10 = 3/5 d Solve pls

Mathematics
1 answer:
ryzh [129]3 years ago
8 0

Answer:

1/3D + 10 = 3/5D

10 = 3/5 D ÷ 1/3 D

10 = 3D/5 ÷ D/3

10 = 3D/5 × 3/D

(btw there is no cross cancleing, just straight up multiply.)

<u>next</u>

10 = 9D/5D

cancel the 10 and 5D to make 10 to 2, and 5d to D.

Next, cancel both the D's (the 9d and the d (the d becomes 1 which is  just 9 over nothing. translates to just a simple 9.))

there is a 2 on the opposite side of the 9, so bring it under 9. so 9/2

then divide to get 4.5

4.5 is the answer!

Mark me brainliest if it is correct!

Help with 35 to 40, don’t know if I am right
Sedaia [141]

Step-by-step explanation:

35. 1000 m / 1 km = 10³

Move the decimal point 3 places to the right.

36. 100 cm / 1 m = 10²

Move the decimal point 2 places to the right.

37. 1 mm / 1000 μm = 10⁻³

Move the decimal point 3 places to the left.

38. 1 km / 1000 m × 1 m / 100 cm = 10⁻⁵

Move the decimal point 5 places to the left.

39. 1 Mm / 10⁶ m × 1 m / 10⁶ μm = 10⁻¹²

Move the decimal point 12 places to the left.

40. 100 cm / m × 1000 m / km = 10⁵

Move the decimal point 5 places to the right.
