24 - 3x = -27

therefore -3x = -27-24

-3x = -51
-x= -17
therefore x is 17

Elimination method. -2y = 0.5 - 2x<br> 6х + Зу = 6
AysviL [449]

Answer:

y=-1.5

X=1.75

Step-by-step explanation:

Yuh arrange the equations in order for easy subtracting of the equations.

-2y=0.5-2x. divide both sides by 2 to get y=-x-0.25.

6x+3y=6

3y=-6x+6 then divide both sides by three to get y

y=-2x+2

now arrange

y=-2x+2

y=-x-0.25 then multiple both equations by the cordinates of X value to eliminate x

Solve to find x and y in the diagram.
Kipish [7]

Considering the given <em>information</em> in the question, the value of x is 12^{o}, and that of y is 7.5^{o}.

A <u>transversal</u> is a <em>line</em> that <em>cuts</em> through two given parallel lines. Thus it i<em>ntersects</em> each parallel line at a point, forming <u>four</u> angles each.

From the given <em>information</em> in the question, it can be <em>inferred</em> that:

the given<u> bottom</u> right angle of the first<em> intersection</em> and the bottom right angle with the <em>second intersection</em> are <u>congruent </u>(corresponding angle property).

So that,

(5x+4y)^{o} = (12y)^{o}

5x^{o} = 12y^{o} - 4y^{o}

5x^{o} = 8y^{o}............ 1

Also given that the top <em>right angle</em> at the<u> second</u> intersection is a <em>right </em>angle, then;

    12y^{o} + 90^{o} = 180^{o} (sum of angles on a straight line)

This implies that;

    12y^{o} = 180^{o} -    90^{o}

       12y^{o}  =     90^{o}

So that,

y = \frac{90}{12}

y = 7.5^{o}

Thus substituting the value of y in equation 1, we have;

5x^{o} = 8y^{o}........ 1

     = 8(7.5)

5x = 60

x = \frac{60}{5}

x = 12^{o}

Therefore, x = 12^{o} and y = 7.5^{o}

here a subtraction problem that has been solved incorrectly for 44-16=28 choose the addition sentence that check this subtractio
Mazyrski [523]

Answer:

28+16=44

Step-by-step explanation:

point of correction it has been solved correctly

when subtracting 44 - 16 it gives you 28

=> 44 - 16

=> 28

SO IN ORDER TO CHECK IF THE PROBLEM WAS SOLVE CORRECTLY

you will minus 28 from one of the numbers before the equal sign

the correct option is 28 + 16 equals to 44

=> 28+16=44

The first step of Elimination in solving a system is to find opposites of one of the variable terms. Explain in your own words,
vovikov84 [41]
You need to find opposite terms when using the elimination method to solve a system of equations so that way you can find out the y or the x after you have crossed out the fraternal twins. You have to get rid of either the y or x in order to work it out and find the y or x value.
