Answer:

- 6

Step-by-step explanation:

Step 1:

- ( 5z + 12 ) = 18     Equation

Step 2:

- 5z - 12 = 18      Open Parenthises

Step 3:

- 5z = 30     Add 12 on both sides

Step 4:

z = 30 ÷ - 5     Divide

Answer:

z = - 6

Hope This Helps :)

Answer: z = -6

Step-by-step explanation:

Hi there! I will be showing you how to solve the given equation. If you have any questions feel free to comment it down below.

Step 1: Remove parentheses.

-5z - 12 = 18

Step 2: Add 12 to both sides.

-5z = 18 + 12

Step 3: Simplify 18 + 12 to 30.

-5z = 30

Step 4: Divide both sides by -5.

z = [tex]-\frac{30}{5}[/tex]

Step 5: Simplify [tex]\frac{30}{5}[/tex] to 6.

z = -6

I hope I helped you :)

Answer:

x=5 gg ez

Step-by-step explanation:

Answer:

x =12

Step-by-step explanation:

angle 5 = 65

65 + (11x - 17) = 180 (supplementary angles)

11x + 48 = 180

11x = 132

x = 12

Yes, the shape I can onto shape II by a sequence of transformations.

Two images are given we have to determine that whether any of shape can onto other shapes.

A graph can be defined as a pictorial representation or a diagram that represents data or values.

The shape I can be mapped into shape II through a series of transformations.

The first sequence would involve translating shape I 8 units up and 4 units left, reflecting shape I across the x-axis, then rotating shape I 90 degrees counterclockwise about the origin.

Therefore, the shape I can onto shape II by a sequence of transformations.

#SPJ2

Step-by-step explanation:

we know that midpoint of a segment is found from formula

x=(x1+x2)/2

and y=(y1+y2)/2

in this case x=3 and y=4 x2=-1 and y2=2

so x1=2x-x2 =2*3-(-1)=6+1=7

y1=2y-y2=2*4-2=8-2=6

the other endpoint is (7,6)

Answer:

x = -5

Step-by-step explanation:

Since these two triangles are similar, the ratio between the corresponding lengths of each triangle will be the same.

This means the ratio between one side of each triangle (e.g. AD and DC) will be the same as the ratio between a different side of each triangle (e.g. BE and BC).

So, to create an equation for the sides which contain the unknown 'x', we must first find the ratio between the two sides by using a different set of sides.

On the right side we are given 9 for AD, and 18 for DC.

9/18 = 0.5

This means that the extra length of the larger triangle from the smaller one (AD) is half the length of the smaller triangle (DC). We can use this to make an equation for x:

If AD/DC = 0.5, then BE/EC will also = 0.5

BE = x+23

EC = x+41

Therefore:

[tex]\frac{x+23}{x+41} = 0.5[/tex]

Now we can solve by multiplying both sides by x+41 to eliminate the fraction:

[tex]x+23=0.5(x+41)[/tex]

Now we multiply out the brackets and move the terms to different sides:

[tex]x+23=0.5x+20.5[/tex]

[tex]0.5x = -2.5[/tex]

[tex]x = -5[/tex]

And if we substitute the -5 into the equations:

-5+23 = 18

-5 + 41 = 36

We will see that -5 does indeed give us the same ratio between the lengths:

18/36 = 0.5

Answer:

<MLI and <KLI

They share the same line and it's 180°

Answer:

Option (1)

Step-by-step explanation:

Lines X and Y are intersecting at a point.

Two pairs of vertical angles have been formed at the point of intersection.

1). ∠1 and ∠3

2). ∠2 and ∠4

It's given that m(∠1) = m∠3 = 55° [Since pair of vertical angles are equal in measure]

If line Y is rotated 5° clockwise about the point of intersection of both the lines,

∠1 and ∠3 both will increase by 5°.

Therefore, measure of angles 1 and angle 3 will become (55° + 5° = 60°).

Option (1) will be the answer.

The new measure of angle 3 is 60 degrees

When a point or line is rotated, it must be rotated about a point of rotation

The angle measure is given as:

[tex]\angle 1 = 55^o[/tex]

By vertical angle theorem, we have:

[tex]\angle 3 = \angle 1[/tex]

So, the angle measure becomes

[tex]\angle 3 = 55^o[/tex]

The angle of rotation is given as: 5 degrees.

So, the new measure of angle 3 is:

[tex]\angle 3 = 55^o + 5^o[/tex]

[tex]\angle 3 = 60^o[/tex]

Hence, the new measure of angle 3 is 60 degrees

Answer:

The area of the triangle DEF is 10.

Step-by-step explanation:

Area of a Triangle:

A triangle of base B and height H (both must be perpendicular) has an area of:

[tex]\displaystyle A=\frac{BH}{2}[/tex]

The image below shows the triangle formed by the points DEF. It's important to notice the points E and F lie on the same horizontal line because they both have the same y-coordinate.

This fact simplifies the calculations since we can easily compute the length the of base as the difference of their x-coordinates:

B=3-(-2)=3+2=5

Being the base of a horizontal line, the height of the triangle can be calculated as the difference of y-coordinates of D and the height of that line.

H=2-(-2)=4

With these two values, we calculate the area:

[tex]\displaystyle A=\frac{5*4}{2}=10[/tex]

The area of the triangle DEF is 10.

Answer:

Jim is correct.

Step-by-step explanation:

Given that:

Total people = 100

People who exercise in morning = 35

People who exercise in the afternoon= 45

People who exercise in the evening = 20

Ratio claimed by Tara = 33:55, 48:88, and 20:65

Ratio claimed by Jim = 35:100, 45:100, and 20:100

To find:

who is correct ?

Solution:

Looking at the ratio claimed by Tara, the ratio are number which are not known to us.

Therefore, the ratio claimed by Tara can not be correct.

Now, looking at the ratio claimed by Jim:

35:100, 45:100, and 20:100

35 is the number of people who exercise in morning.

45 is the number of people who exercise in evening.

20 is the number of people who exercise in night.

and 100 is the total number of people.

Therefore, this ratio represents the "Part-to-whole" ratio.

So, Jim is correct.
