5x-2y=305x−2y=30

Mathematics

1 answer:

Romashka [77]2 years ago

5 0

Answer:

Step-by-step explanation:

For the point to be a solution to the equation, it has to lie on the line 5x -2y= 30 and therefore must satisfy the equation.

5x -2y= 30

When x=8,

5(8) -2y= 30

40 -2y= 30

40 -30= 2y (bring constant to 1 side)

2y= 10 (simplify)

y= 10 ÷2

y=5

Thus the missing value is 5.

Which number can each term of the equation be multiplied by to eliminate the decimals before solving?

Sati [7]

Ok...

5.6 = 56/10 = 560/100

1.1 = 11/10 = 110/100

0.12 = 12/100

--------------

$\frac { 560 }{ 100 } j-\frac { 12 }{ 100 } =4+\frac { 110 }{ 100 } j\\ \\ \\ 100\times \left( \frac { 560 }{ 100 } j-\frac { 12 }{ 100 } \right) =\left( 4+\frac { 110 }{ 100 } j \right) \times 100\\ \\ 560j-12=400+110j\\ \\ 560j-110j=400+12\\ \\ 450j=412\\ \\ j=\frac { 412 }{ 450 }$

So, the answer is: 100

You could multiply both sides of the equation by 100 to get the value of (j) quickly.
