Let's start by cleaning up this equation to make it easier to read by putting all the variables on one side and everything else on the other side using subtraction and addition. Then simplify.
1) Original equation 
<span>a + 3 + 2a = -1 + 3a + 4

2) Subtract 3 from both sides
a + 2a = -3 - 1 + 3a + 4

3) Subtract 3a from both sides
a + 2a - 3a = -3 - 1 + 4

4) Simplify
3a - 3a = -4 + 4
0 = 0

Since 0 = 0 is always true, this equation as an unlimited number of solutions. No matter what you put in for the variable a, it will all cancel out, and you'll get 0 = 0!

------

Answer: Infinite number of solutions

A 2.7 meter ladder leans against a house forming
mrs_skeptik [129]

Answer:

1.35m

Step-by-step explanation:

A 2.7 meter ladder leans against a house forming a 30° angle with the house. Exactly how far is the base of the ladder from the house?

We solve the above question using the Trigonometric function of Sine

cos theta = Opposite/Hypotenuse

From the question

Opposite = Distance of base of the ladder from the house = x

Hypotenuse = Length of the ladder = 2.7m

Theta = 30°

Hence,

sin 30 = x/2.7 m

Cross Multiply

x = sin 30 × 2.7m

x = 1.35m

Option b is correct.

expeople1 [14]

Answer:

Option d - 204 m

Step-by-step explanation:

Given : The atmospheric pressures at the top and the bottom of a building are read by a barometer to be 96.0 and 98.0 kPa. If the density of air is 1.0 kg/m³.

To find : The height of the building ?

Solution :

We have given atmospheric pressures,

P_{\text{top}}=96\ kPa

P_{\text{bottom}}=98\ kPa

The density of air is 1.0 kg/m³ i.e. \rho_a=1\ kg/m^3

Atmospheric pressure reduces with altitude,

The height of the building is given by formula,

H=\frac{\triangle P}{\rho_a\times g}

H=\frac{P_{\text{bottom}}-P_{\text{top}}}{\rho_a\times g}

H=\frac{(98-96)\times 10^3}{1\times 9.8}

H=\frac{2000}{9.8}

H=204\ m

Therefore, Option d is correct.

The height of the building is 204 meter.
