You have to start by using the distributive property on the left side.
3(2x-7)=5x+4
6x-21=5x+4    Then remove and combine alike terms.
    +21      +21
6x=5x+25
-5x  -5x
x=25

gross income £12000 tax free allowance £6475 what is taxable amount @20%, tax payable,net income and weekly net amount how to wo
olganol [36]
We calculate for the taxable income by subtracting the tax free allowance from the gross income.

          Taxable income = Gross income - tax free allowanc
           Taxable income = (£12,000 - <span>£6,475)
                                    = </span><span>£5,525

Hence, the taxable income is equal to </span><span>£5,525.

Net income: 
This would be equal to the gross income minus the amount of taxes to be paid.
 
                 Net income = Gross income - amount of tax to be paid
                 Net income = (</span><span>£12,000) - (0.20)($5,525)
                 Net income = $10,895

Therefore,

Oduvanchick [21]
2/4 --> Once simplified by dividing each fraction part by 2 can get 1/2 

4/8 --> Once simplified by dividing each fraction part by 4 can get to 1/2 

2/5 --> Cannot be simplified by any numbers 

7/14 --> Once simplified by dividing each fraction part by 7 can get to 1/2 

---------

2/5 is not equal to 1/2 <span>✔</span>

A boat travels 8 miles north from point A to point B. Then it moves in the direction S 40°W and reaches point Finally, it turns
uysha [10]

Answer:

B.18. 44 miles

Step-by-step explanation:

We are given that

Distance between A and B=8 miles

Angle B=Angle BCQ=40 degree (Alternate interior angles)

Angle ACB=180-Angle ACP-Angle BCQ

Angle ACB=180-40-40=100 degree

In triangle ABC

Angle A+ Angle B +Angle C=180 degree using sum of angles of triangle property

Substitute the values

\angle A+40+100=180

\angle A+140=180

\angle A=180-140

\angle A=40 degree

Angle A=Angle B

When two angles are equal of a triangle then the triangle is isosceles triangle.

Therefore, triangle ABC is an isosceles triangle.

\implies BC=AC

Now, Sine law

\frac{a}{sin A}=\frac{b}{sin B}=\frac{c}{sin C}

Using the sine law

\frac{BC}{sin 40}=\frac{AB}{sin 100}

\frac{BC}{sin 40}=\frac{8}{sin 100}

BC=\frac{8\times sin40}{sin 100}

BC=5.22

AC=BC=5.22 miles

Now, total distance covered by the boat=AB+BC+AC

Total distance covered by the boat=8+5.22+5.22=18.44 miles

Hence, option B is correct.
