Answer:

<em><u>z = -3</u></em>

Step-by-step explanation:

<u>Step 1: Simplify both sides of the equation. </u>

z+7=−z+1

<u>Step 2: Add z to both sides. </u>

z+7+z=−z+1+z

2z+7=1

<u>Step 3: Subtract 7 from both sides. </u>

2z+7−7=1−7

2z=−6

<u>Step 4: Divide both sides by 2. </u>

<u>2z</u>   =  <u>−6 </u>

Does anyone know how to do this
Doss [256]

Answer :Plotting the points into the coordinate plane gives us an observation that this quadrilateral with vertices d(0,0), i(5,5) n(8,4) g(7,1) is a KITE, as shown in figure a.

Step-by-step explanation:

Considering the quadrilateral with vertices

d(0,0)

i(5,5)

n(8,4)

g(7,1)

Plotting the points into the coordinate plane gives us an observation that this quadrilateral with vertices d(0,0), i(5,5) n(8,4) g(7,1) is a KITE, as shown in figure a.

From the figure a, it is clear that the quadrilateral has

Two pairs of sides

Each pair having two equal-length sides which are adjacent

The angles being equal where the two pairs meet

Diagonals as shown in dashed lines cross at right angles,  and one of the diagonals does bisect the other - cuts equally in half

Please check the attached figure a.

There are two red jars of marbles and one blue jar of marbles jars of a certain color have the same number of marbles in them. T
satela [25.4K]
We can set up an equation to solve this problem.  I am setting the number of marbles in a red jar to R.

R + R + R - 16 = 41

We solve this by adding 16 to both sides and combining all of the R terms..  This gives us:

3R = 57

We can finish this problem by dividing both sides by 3.

R = 19.  So, there are 19 marbles in a red jar.

We can easily figure out how many marbles are in a blue jar by subtracting the total amount of marbles in 2 red jars from the total amount of marbles.  I am setting the amount of marbles in a blue jar to B.

41 - 19*2 = B

B = 3

So, there are 3 marbles in a blue jar and 19 marbles in a red jar.

Write y=1/8x+7 in standard form using intergers
lakkis [162]

Answer:

B) -x+8y=56

Step-by-step explanation:

y=1/8x+7

Multiply by 8 to clear the fraction

8y = 8(1/8x+7)

Distribute

8y = 8*1/8x +8*7

8y = x+56

Subtract x from each side

-x+8y = x-x+56

-x+8y = 56
