Answer:
To make x the subject of the equation means to solve the equation for x (get x by itself on one side). We do the order of operations in reverse, because we are using inverse operations. First, add the 2 to both sides (to keep the equation “balanced” we must do the same thing to both sides). y+2=3x. Then divide both sides of the equation by 3 (or multiply both sides by 1/3.

Answer:
Distance of ladder top from ground = 9.2 meter (Approx.)
Step-by-step explanation:
Given:
Angle of elevation between ground and ladder = 43°
Length of ladder = 13.5 meter
Find:
Distance of ladder top from ground
Computation:
Length of ladder = Hypotenuse
Distance of ladder top from ground = Perpendicular
Sinθ = Perpendicular / Hypotenuse
Sin 43 = Distance of ladder top from ground / Length of ladder
0.6819 = Distance of ladder top from ground / 13.5
Distance of ladder top from ground = 9.20565
Distance of ladder top from ground = 9.2 meter (Approx.)

Answer: r=3v/2nh
Step-by-step explanation:
A whole number is a number that has no fractional representation.
Let's test all the options for the value of x.
When dividing a fraction by another fraction, the divisor will be in its reciprocal form.
1. 3/4 × 2/3
= 6/12 = 1/2
1/2 isn't a whole number.
2. 3/4 × 2/1
= 6/4 = 3/2
3/2 isn't a whole number.
3. 3/4 × 6/1
= 18/4 = 9/2
9/2 isn't a whole number.
4. 3/4 × 8/1
= 24/4 = 6
6 is a whole number.
Hence the answer is 1/8.
Hope it helps. :)
