Find the value of x:

Answers

Answer:

x = 3

Step-by-step explanation:

These angles are vertical angles. Vertical angles equals to on another but on the opposite side. Since they equal to another you do:

(10x + 1) = (12x - 5)

Add 5 on both sides:

10x + 6 = 12x

Subtract 10x on both sides:

6 = 2x

Divide 2 on both sides:

3 = x

Answer:

(10x+1)°=(12x-5)°. [vertically opposite angle]

1+5=12x-10x

6= 2x

3=x

therefore,x=3

Answers

Answer:

Step-by-step explanation:

1) Check whether the graph is inclusive or exclusive. Inclusive graphs are equal to or greater/less than, whereas exclusive graphs are just greater/less than. A filled circle is inclusive, and a non-filled circle is exclusive. We see that in the graph, the circle is filled meaning it is inclusive. Secondly, we see that the number line goes forever when it is greater than(or equal to) 3. From these two pieces of information, we see that the answer is choice D.

ik its so simple i just cant figure it out ;-; pls help

Answers

Answer:

what are we looking for?

I'm not exactly sure what you need to find so I'll just put this:

If you need to find the area:

A = l x 2

A = 11 x 7.7

A = 84.7 cm^2

If you need to find the perimeter:

P = 2(l + w)

P = 2(11 + 7.7)

P = 22 + 15.4

P = 37.4 cm

Maggie is buying a jacket. The expression shown represents the sales tax on the jacket price, j.

0.08j
Write an expression in terms of j to represent the total amount that Maggie spends on the jacket, including tax.

Answers

Answer: 1.08j

Step-by-step explanation: if we add 8% of something to itself, we now have 108%, right

1.08j

I’m not 100% sure tho

The expression represents the total amount that Maggie spends on the jacket, including tax is 1.08j.

What is Percentage?

A percentage is a way to describe a part of a whole. such as the fraction 1/4 can be described as 0.25 which is equal to 25%.

To convert a fraction to a percentage, convert the fraction to decimal form and then multiply by 100 with the '%' symbol.

As it is given that the cost of the jacket is j, while the tax on the jacket is 0.08j. therefore, the total cost of the jacket can be written as the sum of the cost of the jacket and the tax on the jacket.

Thus, the total cost of the jacket = Cost of jacket + Tax on the jacket

                                                       = j + 0.08j

                                                       = 1.08j

Hence, the expression represents the total amount that Maggie spends on the jacket, including tax is 1.08j.

NO LINKS PLEASEE!! IM BEGGING YOU NO LINKSS!!!

Answers

Answer:

A = (1/2)Pa = Pa/2

 

You can multiply both sides by 2 to eliminate the fraction on the right side:

 

2A = 2(Pa/2) = Pa

 

Then divide both sides by a (or multiply both sides by 1/a) to leave P alone on the right side:

 

(2A)(1/a) = 2A/a = (Pa)(1/a) = P

 

Rewriting:

 

P = 2A/a

 

You could also have divided by a first then multiplied by 2; which you should do first does not matter in this example.

Answer:

1. Mean: 10 Median: 11 Mode: 13

2. Mean: 26.7 Median: 20.5 Mode: 20

Step-by-step explanation:

1. Mean: 6+7+11+13+13 = 50 then, 50/5 = 10

Median: 6, 7, 11, 13, 13 in the middle: 11

6- crossed

13- crossed

7- crossed

13- crossed

That leaves 11!

Mode: 13 appears two times. All the other numbers only appear once.

2. Mean: 0+20+20+30+40+70 = 160 then, 160/6 = 26.7 ( rounded to nearest tenth)

Median: 0, 20, 20, 30, 40, 70

0- crossed

70- crossed

20- crossed

40- crossed

20- crossed

30- crossed

They all are crossed, but the last 2 to be crossed are 20 and 30. The middle of those two numbers is 20.5 therefore, the median is 20.5!

Mode: 20 appears twice while the rest only appears once.
