500x+6y=11216. and 800x+4y=9344 solve substuition method
Sedaia [141]

we have

500x+6y=11,216 ---------> equation 1

800x+4y=9,344 ---------> equation 2

<u>In the equation 1 clear variable x</u>

500x+6y=11,216\\ 500x=11,216-6y

x=22.432 -0.012y ----------> equation 3

Substitute the equation 3 in the equation 2

800*[22.432 -0.012y]+4y=9344

800*[22.432 -0.012y]+4y=9,344\\17,945.6- 9.6y+4y=9,344\\9.6y-4y= 17,945.6-9,344\\ 5.6y=8,601.6\\y=8,601.6/5.6\\y= 1,536

<u>Find the value of x</u>

x=22.432 -0.012y

x=22.432 -0.012*1,536

x=4

therefore

<u>the answer is</u>

x=4

y=1,536

3(x-4)= 2(x + 5) <br> Find the number
ohaa [14]

Answer:

x=22

Step-by-step explanation:

Reorder the terms:

3(-4 + x) = 2(x + 5)

(-4 * 3 + x * 3) = 2(x + 5)

(-12 + 3x) = 2(x + 5)

Reorder the terms:

-12 + 3x = 2(5 + x)

-12 + 3x = (5 * 2 + x * 2)

-12 + 3x = (10 + 2x)

Solving

-12 + 3x = 10 + 2x

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '-2x' to each side of the equation.

-12 + 3x + -2x = 10 + 2x + -2x

Combine like terms: 3x + -2x = 1x

-12 + 1x = 10 + 2x + -2x

Combine like terms: 2x + -2x = 0

-12 + 1x = 10 + 0

-12 + 1x = 10

Add '12' to each side of the equation.

-12 + 12 + 1x = 10 + 12

Combine like terms: -12 + 12 = 0

0 + 1x = 10 + 12

1x = 10 + 12

Combine like terms: 10 + 12 = 22

1x = 22

Divide each side by '1'.

x = 22

Simplifying

x = 22

What are the zeros of the function? f(t)=t2−13t+36 Enter your answers in the boxes. and
Brrunno [24]

Answer:

4 and 9

Step-by-step explanation:

t2-13t+36=0

factors of 36 are:

1,2,3,4,6,9,12,18,36

factors that add up to 13 are: 9*4

factorise the equation:

(t-9)(t-4)=0

t-9=0    --->   t=9

t-4=0    ---> t=4
