Which ordered pair is a solution to the system of linear equation? 2x+ 3y=6 <br> -3x+5y=10

allochka39001 [22]

Answer:

Step-by-step explanation:

2x + 3y = 6________( 1 )

-3x + 5y = 10_______( 2 )

( 1 ) × 3 ---- 6x + 9y = 18_____( 3 )

( 2 ) × 2 ---- -6x + 10y = 20_____( 4 )

$(4) + (3) \\ 6x + 9y + ( - 6x + 10y) = 20 - 18 \\ 6x + 9y - 6x - 10y = 2 \\ y = 2$

y = 2 ,

$2x + 3y = 6 \\ 2x + 3(2) = 2 \\ 2x + 6 = 2 \\ 2x = 2 - 6 \\ 2x = - 4 \\x = \frac{ - 4}{2} \\ x = ( - 2) \\$

Answer:

$9C=5(F-32)$

Step-by-step explanation:

The equation which can convert the temperature from degree Celsius into degree Fahrenheit is given as under

$9C=5(F-32)$

We can solve it further for F as

$9C=5F-5 \times 32$

$9C=5F-160$

$9C+160=5F$

Dividing both sides by 5 we get

$\frac{9C}{5}+32=F$

$F=\frac{9C}{5}+32$

Now substituting values of C in this equation will give us the corresponding values of F

Ex : C=1

$F=\frac{ 9\times 1}{5}+32$

$F=\frac{ 9+160}{5}$

$F=\frac{ 169}{5}$

Hence 1 degree Celsius is $\frac{ 169}{5}$ degree Fahrenheit

PLEASE HELP TRYING TO MAKE HONOR ROLL

Answer:

Hulian's age is 7.

Thomas's age is 22.

Step-by-step explanation:

Let Hulian = h

Let Thomas = t

Set the system of equation:

h = t - 15

h + t = 29

Plug in t - 15 for h in the second equation:

(t - 15) + t = 29

Simplify. Combine like terms:

2t - 15 = 29

Isolate the variable, t. Note the equal sign, what you do to one side, you do to the other. Do the opposite of PEMDAS. First, add 15 to both sides:

2t - 15 (+15) = 29 (+15)

2t = 44

Divide 2 from both sides:

(2t)/2 = (44)2

t = 44/2

t = 22

Plug in 22 for t in one of the equations:

h = t - 15

h = 22 - 15

h = 7

Hulian's age is 7.

Thomas's age is 22.
