Answer:

2x° + 10° = 90°

3x° = 120°

2x° + 5° = 85°

2x° - 15° = 65°

Step-by-step explanation:

360° = 3x° + 2x° + 5° + 2x° + 10° + 2x° - 15°

360° = 3x° + 2x° + 2x° + 2x° + 5° + 10° - 15°

360° = 9x°

9x° = 360°

x° = 360° : 9

x° = 40°

2x° + 10°

= 2(40°) + 10°

= 80° + 10°

= 90°

3x°

= 3(40°)

= 120°

2x° + 5°

= 2(40°) + 5°

= 80° + 5°

= 85°

2x° - 15°

= 2(40°) - 15°

= 80° - 15°

= 65°

Answer:

There are multiple ways to expand but I did it by using sum/difference formulas.

3(x-2) = 3x-6

8(2x+2) = 16x+16

5(x-1) = 5x-5

2(6x+3y) = 12x+6y

Answer:

A

Step-by-step explanation:

9 > 3 + 2x

6 > 2x

3 > x

or

x < 3

and that means 3 is NOT included (otherwise there must be a smaller or equal sign). hence A is the right answer.

The graph of the solution set [tex]9 > 3 + 2x[/tex]  is represented by the inequality relation x < 3.

The correct answer is Option A.

Given data:

The inequality is represented as 9 > 3 + 2x

The solution set of the inequality 9 > 3 + 2x can be found by isolating x on one side of the inequality:

Subtract 3 from both sides: 9 - 3 > 2x

Simplify: 6 > 2x

Divide both sides by 2: 3 > x

So, the solution set is x < 3.

Graphically, this represents all the values of x that are to the left of (less than) 3 on the number line. It forms an open interval to the left of 3. The graph consists of all real numbers less than 3, not including 3 itself. In interval notation, this can be written as (-∞, 3).

Hence, the inequality is x < 3.

y = -2x - 5

Step-by-step explanation:

y = is a standard for any equation, as is the use of x as a variable, unless something else is specified.

-2x is the way to denote a slope of -2, and -5 gives you the y-intercept of 5. One point on this line would be (0, -5).

Answer:

The inequality is x/5 < 20, and 100 is in the box.

Step-by-step explanation:

x = the amount she spends in June.

So, since she spends an equal amount five times, the amount she spends each time is x/5.

She wants this to be less than 20.

So, x/5 < 20.

Solving for x by multiplying both sides of the equation by yields

x < 5 * 20

x < 100, so that 100 goes into the box.

Answer:

X-ray technicians, also referred to as radiologic technologists, would need math skills to be able to use accurate calculations when mixing chemicals used in x-ray imaging processes. In addition to this, the critical and logical thinking abilities practiced in the study of mathematics are useful in the day to day job, especially because working with imaging technology and machines to get detailed images for physicians to view is crucial to patient care and treatment.

Education for an associate's degree in radiologic technology is going to be focused heavily on STEM related courses such as anatomy, radiation safety, imaging procedures, and pathology. For this reason, it is recommended that high school students planning on pursuing this educational path take plenty of classes in math, science, and technology.

Radiologic technology job opportunities are expected to increase by 9 percent between 2018 and 2028 according to the Bureau of Labor and Statistics. This is greater than the 5 percent average increase projected for all other jobs, which means radiological technology is a career with a strong and stable outlook.

Because vertical angles are always equal, we want to solve [tex]50x+10=70x-10[/tex].

We can add 10 to both sides to get [tex]50x+20=70x[/tex].

We can subtract [tex]50x[/tex] from both sides to get [tex]20=20x[/tex].

Lastly, we divide both sides by 20 to get [tex]1=x[/tex].

So, [tex]\boxed{x=1}[/tex] and we're done!

The check is left as an exercise to the reader.

Answer:

x= 1

Step-by-step explanation:

TO solve you can use the equation 50x+10=70x-10.

First, subtract 10 from both sides:

50x= 70x-20

Then subtract 70x from both sides:

-20x=-20

Then divide by -20:

x=1

Check your work:

50(1)+10=70(1)-10

50+10=70-10

Step-by-step explanation:

Because they are scaled copies, the ratios of the sides are equal.

Figure A has a base of 6 units by inspection.

Figure B has a base 3 units by inspection.

So, the scale factor from Figure A to Figure B is [tex]3/6=\boxed{1/2}[/tex] and we're done!

The scale factor from Figure A to Figure B is 1/2

Figure A:

Base = 6 units

Height = 4 units

Figure B:

Base = 3 units

Heights = 2 units

Using Base of the shape:

Scale factor = Dimensions of the new shape ÷ Dimensions of the original shape

= 3 units / 6 units

= 1/2

Using Height of the shape:

Scale factor = Dimensions of the new shape ÷ Dimensions of the original shape

= 2 units / 4 units

= 1/2
