Answer:

z=7

Step-by-step explanation:

Step 1: Simplify both sides of the equation.

5(z+6)−2=9z

(5)(z)+(5)(6)+−2=9z(Distribute)

5z+30+−2=9z

(5z)+(30+−2)=9z(Combine Like Terms)

5z+28=9z

Step 2: Subtract 9z from both sides.

5z+28−9z=9z−9z

−4z+28=0

Step 3: Subtract 28 from both sides.

−4z+28−28=0−28

−4z=−28

Step 4: Divide both sides by -4.

−4z/−4=−28/−4

z=7

Distribute, so 5z+28+9z, then subtract 5z, and you get 4z=28. Divide by 4 so x=7

Samantha drew Triangle JKL with the coordinates (2,3), (4, 3) and (5,2). She reflected this image over the x-axis to create an i

zavuch27 [327]

Answer:

J'(2,-3), K'(4, -3) and L'(5,-2)

Step-by-step explanation:

The given triangle has vertices at J(2,3), K(4, 3) and L(5,2).

The transformation rule for a reflection in the x-axis is:

$(x,y)\to (x,-y)$

We substitute the points to obtain the coordinates of the image triangle J'K'L'

$J(2,3)\to J'(2,-3)$

$K(4,3)\to K'(4,-3)$

$L(5,2)\to L'(5,-2)$

In other words, we negate the y-coordinates of triangle JKL to obtain the coordinates of J'K'L'

Your family went on a road trip. They drove for 12 hours in one day. Your mom drove 5 / 6 of that time. How much of the time did

Viefleur [7K]

Answer:

Step-by-step explanation:

The first thing you do is:

12 % 6 = 2

Then you have to:

2 x 5 = 10

You divide the denominator then multiply it by the Numerator
