The solution of the liner equation 6k + 10.5 = 3k + 12 is k = 1/2.

<h3>What is Linear Equation?</h3><h3>Linear equations are equations of the first order. The linear equations are defined for lines in the coordinate system. When the equation has a homogeneous variable of degree 1 (i.e. only one variable), then it is known as a linear equation in one variable.</h3>

Here, 6k + 10.5 = 3k + 12

6k - 3k = 12 - 10.5

3k = 1.5

k = 1.5/3

k = 1/2

Thus, The solution of the liner equation 6k + 10.5 = 3k + 12 is k = 1/2.

Find the amount of interest payable if $400 is borrowed at 14% interest and is to be repaid in 6 months

Shtirlitz [24]

Answer:

The amount of interest payable after 6 months is $28.

Step-by-step explanation:

Here, the Principal amount borrowed = $400

Rate of Interest = 14%

Time = 6 months = 6 / 12 years = 0.5 year

Now, SIMPLE INTEREST = $\frac{P \times R \times T}{100}$

So, here SI = $SI = \frac{400 \times 14 \times 0.5}{100} = 28$

or, SI = $28

Hence, the amount of interest payable after 6 months is $28.

What number should be added to both sides of the equation to complete the square? x2 8x = 4

Levart [38]

You would take half of the x term...and square it
so half of 8 is 4....4^2 = 16
u would add 16 to each side

7x+2y=19<br> 7x+8y=13<br> Please solve it by Simultaneous method

elixir [45]

Answer:

y=-1

x=3

Step-by-step explanation:

7x+2y=19-----(1)

7x+8y=13------(2)

(1)-(2)

(7x+2y)-(7x+8y)=19-13

7x+2y-7x-8y=6

+2y-8y=6

-6y=6

y=-1

by substitute in (1)

7x+2*(-1)=19

7x-2=19

7x=19+2

7x=21

x=21/3

x=3

HJ = 23.5 in

$\textsf{ \underline{\underline{Steps to solve the problem} }:}$

Take HJ = a, GH = b and GJ = c

a = b + 2

c = a + b - 17

a + b + c = 73

put the value of a from equation 1 in equation 2

c = (b + 2) + b − 17

c = 2b − 15

now, put the value of a and c in equation 3

b + 2 + b + 2b − 15 = 73

4b − 13 = 73

4b = 86

b = 21.5 in

Now, we need to find HJ (a)

a = b + 2

a = 21.5 + 2

a = 23.5 in

${ \qquad \large \sf {Conclusion} :}$

HJ = 23.5 in
