Answer:

hi

Step-by-step explanation:

Answer:

70 degrees

Step-by-step explanation:

2x+3x-20+x+20=180

( angles in a triangle add up to 180 degrees)

as you want to find one x you need to move everything else to the other side: first collect all the like terms: 6x=180

in order to find x you need to divide 180 by 6 which is equal to 30

therefore x=30

if you substitute this into XYZ it would be: 3(30)-20

90-20=70

therefore XYZ=70 degrees

Hope this helped

Answer:

70

Step-by-step explanation:

So we know that the angles of a triangle equal up to 180 degrees. So let's make an equation. So we can do:

2x+(3x-20)+(x+20) = 180

Simplify:

6x=180

x=30

We can also plug this in to check our work. So it would be:

60+(90-20)+(30+20)

simplify

70+50+60=180

Then we have to find angle XYZ so we do 90-20=70

Answer:

t = 2.7

Step-by-step explanation:

5.3 + 5.3 = 10.6

16 - 10.6 = 5.4

5.4 ÷ 2 = 2.7

Answer:

12x+20

Step-by-step

nice

Replace x with 11 and solve:

4(3(11) + 5)

3 x 11 = 33:

4(33 + 5)

33 + 5 = 38:

4(38)

4 x 38 = 152

answer: 152

Answer: 8

Step-by-step explanation:
I wouldn’t use a proportion to solve this. I would simply take .125 times 64 and get 8

Answer:

the answer is 8.

Answer:

x ≥ 4; solid circle at 4 and shaded to the right

Step-by-step explanation:

Given:

 x +2 ≥ 6

Subtract 2

 x +2 -2 ≥ 6 -2

 x ≥ 4

This is graphed as a solid circle at x=4 and shaded to the right (where x > 4).

Answer:

For the first one it would be E.

Step-by-step explanation:

Answer:

7: A, B, E

8: D

Step-by-step explanation:

for 7:

all i did was make a mental picture and solve after that

for 8:

this is simple. make a circle graph, with radii 6, and plot the points. If they are on the edges of the circle, they are 6 units away from origin. ive attached an image of this lol

Answer:

Hello! Elizabeth is here! The answer to your question is 3) M and N are similar but not congruent!

Step-by-step explanation:

As you can see on the coordinate grid, the M is at the (-4,3) and the N is at (4,1/2) , both M & N are similar from it size, sure but their coordinate location is quite different, or should I say M & N is not similar with congruent.

Hope this helped and have a wonderful day!

Answer:

27°

Step-by-step explanation:

when you see a square to represent that angle, that means that angle is 90 degrees (a right angle)

the angle of a straight line is 180

so [tex]180-90=90[/tex]

[tex]3x+9=90[/tex]

[tex]3x=81[/tex]

[tex]x=27[/tex]

Answer: C

Step-by-step explanation

You have to divide the output, which in this case is Y (5), into the input, also known as X (1). You will then get your answer, which is 5 dollars per car.  To put that into an equation, it will be: y = 5x.

Here is the work:

5(y) ÷ 1(x) = 5  

y = 5x

Answer:20

Step-by-step explanation:

Answer:

StartFraction 1 centimeter over 2.5 meters EndFraction = StartFraction 12 centimeters over x meters EndFraction

Step-by-step explanation:

The complete question is

Eveline made a scale drawing of a patio she is planning to build.

1 centimeter = 2.5 meters. Triangle A B C. Side A is 12 centimeters, side B is 5 centimeters, and side C is 13 centimeters.

Which proportion could Eveline use to find the length of side A?

StartFraction 1 centimeter over 2.5 meters EndFraction = StartFraction 13 centimeters over x meters EndFraction

StartFraction 1 centimeter over 2.5 meters EndFraction = StartFraction 12 centimeters over x meters EndFraction

StartFraction 12 centimeters over 2.5 meters EndFraction = StartFraction x centimeters over 1 meter EndFraction

StartFraction 1 centimeter over 12 meters EndFraction = StartFraction 2.5 centimeters over x meters EndFraction

The picture of the question in the attached figure

we know that

The scale drawing is

That means

1 cm in the drawing represent 2.5 m in the actual

using proportion

Find out the actual length of side A if in the drawing the length is 12 cm

solve for x

The length of side A is 30 meters

The answer is B

Answer:

Yes, the 2 negative signs cancel each other out. The definition of irrational is a repeating decimal that cannot be written as a fraction. 5/7 is a fraction

Step-by-step explanation:

Answer:

  132 units²

Step-by-step explanation:

The figure is a trapezoid, so its area can be found using the formula for the area of a trapezoid.

  A = 1/2(b1 +b2)h

The top "base" is the difference between 21 units and 9 units, so is 12 units. Filling in the numbers, we have ...

  A = 1/2(21 units +12 units)(8 units) = 132 units²

The area of the figure is 132 square units.

Answer:

Hi so you need to find an intersection so like 2/2 and -1/-1 and you get one for both then you go up 3 from -1/-1 and go over 2 to get your 2/2 now you take 3 divided by 2=1.5

Answer:

A. [tex]y=\frac{3}{2}x-1[/tex]

B. [tex]y=\frac{3}{2}x[/tex]

Step-by-step explanation:

For the graph shown, the slope is [tex]\frac{3}{2}[/tex] and the y-intercept is -1. For the new line, it would have the same slope, but would have a y-intercept of 0.

Answer:

it is a rotation of 180 degrees and a reflection over the y -3 or y -4 axis

Step-by-step explanation:

Rigid motion: Type of transformation that creates congruent figures (that's the definition, so I can't really explain much)

Congruent: Same shape, same size

Dilation: Enlarge or reduce a shape

Rotation: Twists a shape

Reflection: Flips a shape

Translation: Slides a shape

Answer:

0.0005 km, 100000 cg, 0.2 L, 100 cm, 0.35 cm

Step-by-step explanation:

50 cm = 0.0005 km

3) 1000 g = 100000 cg

5) 1 kg = 1000000 mg

2) 200 mL = 0.2 L

4) 0.01 hm = 100 cm

6) 3.5 mm = 0.35 cm
