Answer:
[tex] \huge{ \boxed{ \boxed{ \sf{ \red{ \sf{x = 1}}}}}}[/tex]
Step - by - step explanation :
[tex] \underline{ \underline{ \sf{Solution}}} : [/tex]
USING ELIMINATION METHOD :
[tex] \sf{ - 3x - 9y = - 12}[/tex] ••••••• equation ( i )
[tex] \sf{ - 3x + 7y = 4}[/tex] ••••••• equation ( ii )
Subtracting equation ( ii ) from ( i )
Note that while subtracting equation ( ii ) from ( i ) , sign of each term of equation ( ii ) changes and hence becomes 3x - 7y = -4.
[tex] \sf{ \cancel{ - 3x} - 9y = - 12}[/tex]
[tex] \sf{ \cancel{3x} - 7y = - 4}[/tex]
_____________________
➺ [tex] \sf{ - 16y = - 16}[/tex]
➺ [tex] \sf{ \frac{ - 16y}{ - 16} = \frac{ - 16}{ - 16}} [/tex]
➺ [tex] \sf{y = 1}[/tex]
The value of y is 1. Since , we are asked to find the value of x , substituting the value of y in equation ( i) , we get :
➺ [tex] \sf{ - 3x - 9 \times 1 = - 12}[/tex]
➺ [tex] \sf{ - 3x - 9 = - 12}[/tex]
➺ [tex] \sf{ - 3x = - 12 + 9}[/tex]
➺ [tex] \sf{ - 3x = - 3}[/tex]
➺ [tex] \sf{ \frac{ - 3x}{ - 3} = \frac{ - 3}{ - 3}} [/tex]
➺ [tex] \sf{ x = \boxed{ \bold{ \red{ \sf{1}}}}}[/tex]
Hence , the value of x is 1 .

There are many methods to solve such simultaneous equations. They are :
Graphical method : In this method , we find a few pairs of solutions to each of two given equations. The pairs of solutions of each equation are plotted in a graph and by joining them, two separate straight line lines are obtained. The coordinates of the point of intersection of two straight lines are the solutions to the given equation.Elimination method : In this method, we add or subtract the given equations to eliminate one of the two variable by making their coefficients equal. Then , a single equation with one variable so obtained is solved to find the value of the variable. The value of the variable is substituted to any one equation to find the value of the eliminated variable.Substitution method : In this method , a variable is expressed in terms of another variable from one equation and it is substituted in the remaining equations.⋆⋆⋆⋆⋆⋆⋆⋆⋆⋆⋆⋆⋆⋆⋆⋆⋆⋆⋆⋆⋆⋆⋆⋆⋆⋆⋆⋆⋆⋆⋆⋆⋆⋆⋆⋆

Conner had 354$ and spent 243 cents. How much did conner have left and how many dollars? please help. If you do, then I will tell you a secret.
Conner: $354 - 243 cents
243 cents = $2.43 because 100 cents = 1 dollar
Conner: $354 - $2.43 = $351.57
$351.57
He has 351 dollars left.
Answer:
354 - 243 = 111
Step-by-step explanation:
300 - 200 = 100
50 - 40 = 10
4 - 3 = 1
100 + 10 + 1 = 111
Rupra is picking strawberries. For every 5 strawberries she puts in her basket, she eats 2. If she picks 28 strawberries, how many does she eat and how many does she put in the basket?
Answer:
she puts 20 in the basket and she eats 8
Step-by-step explanation:
Step one:
given data
we are told that for every 5 strawberries she puts in the basket, she eats 2
if she picks 28
then she will put 20 in the basket and eat 8
the first 5 she puts in the basket, she ears 2
the second 5 she eats 2, total is 7
the third 5, she eats 2, total is 7
the fourth 5, she eats 2, total is 7
hence she puts 5+5+5+5= 20 in the baskets
and eats 2+2+2+2= 8

Answer:
slope: -3; y-intercept: (0,15)
Step-by-step explanation:
The slope is -3, simply move 3x to the right side for slope intercept form, the y-intercept is where x =0 so set x equalt to zero. 3(0)+y=15, y=15
5 12 14 will form a acute?
True or false
No it won't. it's false
cuz proofs here.
(5²)+(12²)= (169)
√(169) = 13
.. so if 13 was the number at 14
it would have been true.
currently the answer is false
the difference of 2x and 15 is less than or equal to the sum of 4x and 17
Step-by-step explanation:
the difference of 2x and 15 is less than or equal to the
sum of 4x and 17
i.e.,
2x - 15 < 4x + 17
if you want to find ahead then
2x - 15 = 4x + 17
2x - 4x = 17 + 15
- 2x = 32
x = - 32/2
x = - 2

Read the excerpt from Heart of a Samurai and then answer the question.
The strangers leaped out of their boats and pulled them up on the small beach. By signs, they made it clear the castaways should climb aboard.
The fishermen exchanged frightened glances and whispered to one another,
“What about Denzo and Jusuke?”
Gesturing, Manjiro communicated to the strangers about the two men in the cave. Denzo and Jusuke were retrieved, both of them so weak they had to be carried to the boats. Everyone found a place and the sailors shoved off. The two boats rowed away from the island toward an unknown future.
The sun flickered on the restless waves just as it always did. The wind blew just as steadily as it always had. Yet everything had changed. They had been rescued from the island, only to be taken captive by barbarians.
Manjiro stared at the strangers when he thought they weren’t looking. Sometimes he caught them staring at him when they thought he wasn’t looking.
What do the details in this excerpt help readers to infer about the barbarians?
A. They are just as mean and monstrous as the fishermen expect them to be.
B. They are suspicious creatures who seem to be from a place other than Earth.
C. They have a plan to humiliate the fishermen and are waiting for the right time.
D. They are just as curious about the fishermen as the fishermen are about them.

Step-by-step explanation: when you read the question it say select all that apply to form the equation so all you have to do is select the numbers and the variables that are in the equation above.
A fighter pilot needs to make an emergency landing. He needs a clear space that is at least 600 m long to land safely. He is flying at an altitude of 300 m. He sees a small empty field. The angles of depression from the jet to the two ends of the field are 30° and 56° [5]
a) How long is the field?
b) Can he land safely?
(a) See the attached sketch. The jet makes a right triangle with the ground with hypotenuse y. Since the angle of depression is 56°, and the plane in which the jet is flying 300 m in the air is parallel with the ground, the angle of elevation in the right triangle is also 56°. Use the definition of sine to solve for y.
sin(56°) = (300 m)/y → y = (300 m)/sin(56°)
The uppermost angle in the blue triangle has measure equal to the difference between the two given angles of depression, 56° - 30° = 26°, and the rightmost angle is also 30° by the same reasoning as before. Then by the law of sines,
x/sin(26°) = y/sin(30°) → x = sin(26°)/sin(30°) y ≈ 317.2627 m
(b) No, the field is not long enough.
