Answer:

18x - 9 = 72
3(6x - 3) = 72
x = 45

Step-by-step explanation:

Apply the distributed property:

Apply the distributed property: 3/5 × 30x = 18x, 3/5 × 15 = 9
Re-write the equation: 18x - 9 = 72
18x - 9 = 72 is an option listed, so that's one of the answers.

See the other options:

Another option that looks like it could be the answer is 3(6x - 3) = 72
Apply the distributed property like we did above, so it now looks like this: 18x - 9 = 72
This is the same as what we got above, so it is also an answer.

Solve:

Add 9 to each side, so it now looks like this: 18x = 81
Divide each side by 18 to cancel out the 18 next to x. It should now look like this: x = 4.5
x = 45 is an option listed, so that's one of the answers.

I hope this helps!

Aleks04 [339]

Answer:

Tonga trench Elevation = 35,702ft

South sandwich trench elevation = 23,737ft

Step-by-step explanation:

Given the following:

Tonga trench Elevation = 35,702 Feets

South sandwich trench elevation = 23,737 Feets

Expressing both numbers as rational numbers :

Both the Tonga trench Elevation and South sandwich trench elevation are already stated as rational numbers because all integers are rational numbers, be it expressed as a quotient or proportion of integer numbers ( that is numbers that are expressed without decimal components.

Therefore, rational expression for both are :

Tonga trench Elevation = 35,702ft

South sandwich trench elevation = 23,737ft

Answer:

WX < YW < XY

Step-by-step explanation:

<h2>Angle sum property</h2>

Sum of all angles of triangle = 180

114 + 53 + ∠y = 180

167 + ∠Y = 180

∠Y = 180 - 167

∠Y = 13

The side opposite to smallest angle is shortest.

Angles in ascending order: ∠Y < ∠X < ∠W

Sides in ascending order: WX < YW < XY
