Step-by-step explanation:

divide by .4

Answer:

no solution

Step-by-step explanation:

Given

2(x + 1) = 2x + 5 ← distribute parenthesis on left side

2x + 1 = 2x + 5 ( subtract 1 from both sides )

2x = 2x + 4 ( subtract 2x from both sides )

0 = 4 ← not possible

This indicates the equation has no solution

Answer:

See below

Step-by-step explanation:

● 2(x+1) = 2x +5

Multiply 2 by (x+1)

● 2x + 1×2 = 2x+5

● 2x + 2 = 2x+5

Substract 2x from both sides

● 2x+2-2x = 2x+5-2x

● 2 = 5

This is impossible, so this equation has no solution.

Step-by-step explanation:

f(x) when x =10

The part that applies when x=10 is x^2 +3

f(10) = 10^2 +3

       = 100+3

       = 103

f(x) when x =-10

The part that applies when x=-10 is none

There is no part that applies ins -10 < -3

We cannot find a solution since x is in any defined region

Step-by-step explanation:

We can prove this by using similar triangles. We know that angle ABE and ACD are SIMILAR(we know that by the sign in between them).Therefore, we also know that CDA and BEA are similar, and EAB and DAC are similar. Since all the angles are similar, we also know that the side lengths are equal in proportion. AB/AE is equal to AC/AD. When assigned values, that would create a proportion that is equal since the smaller triangle is similar to the bigger one. If you want to create a proof, break each statement into its own section.

Answer:

Step-by-step explanation:

We proceed to calculate the 5.14% of the $1500 in sales during the week

Hence she is paid 1500*(5.14/100)

=  1500*0.0514

= $77.1

And also she is paid 10% of sales over $1500 and she made sales of $7500

her commission is

= (10/100)*7500

=0.1*7500

= $750

Hence in all for the week her commission will be (if she sells $7500)

= 77.1+750

= $827.1

Please let me know if you have any question

Answer:

a = 12   b = -4

Step-by-step explanation:

To solve this equation it would be easiest to use the elimination method

a + b = 8

a - b = 4

a = 12

Now all we have to do is substitute 12 for a in any equation. For this I will use the first one.

12 + b = 8

Lastly subtract 12 from both sides

b = -4

Answer:

a = 6 , b = 2

Step-by-step explanation:

a+b - (a-b) = 2b

8 - 4 = 4

2b = 4

b = 4 ÷ 2

b = 2

When b = 2,

a+2 = 8

a = 8 - 2

a = 6

Answer: plz mark as brainliest

Step-by-step explanation:The table below shows the net effect of a person’s mental state and occupation on his or her truth telling.

Suppose that Dorothy is telling the truth. Then she is sane (and hence a pure mathematician) and Charlie is sane. Bob says that Charlie is insane, so Bob is not telling the truth. Since he says he’s pure, he’s actually applied and hence Charlie is telling the truth. But then he’s applied and sane applied mathematicians do not tell the truth. This is a contradiction.

Therefore, Dorothy is not telling the truth. Thus, both Charlie and Dorothy are insane (hence Dorothy is pure). Consequently, Bob is telling the truth. Therefore Bob is pure (and sane, since he is a truth teller). Since Charlie says that Bob is applied, he is not telling the truth. Since we know that he is insane, he must be pure.

Since Alice says that Charlie is pure, she is telling the truth. Therefore she is insane and consequently applied.

In summary:

Alice is an insane applied mathematician.

Bob is a sane pure mathematician.

Charlie is an insane pure mathematician.

Dorothy is an insane pure mathematician.

Alice: Alice claims to be insane. If she is telling the truth, then her belief is incorrect, and she is, in fact, sane.

Mathematicians and statisticians solve problems in industry, academia, and government by using formulas and data.

Alice: Alice claims that she is insane. If she's telling the truth, her belief is incorrect, and she's perfectly normal. Alice is thus either pure or applied.

Bob: Bob declares himself to be pure. Bob's belief is correct, and he is indeed pure, because pure mathematicians tell the truth.

Charlie claims to be applied, but Alice claims Charlie is pure. Alice's claim about Charlie is true because applied mathematicians lie, and Charlie is actually pure.

Dorothy: Dorothy asserts that she is sane. Dorothy's belief is correct, and she is indeed sane, because the beliefs of sane mathematicians are correct.

Therefore, the four mathematicians are Alice (either pure or applied), Bob (pure), Charlie (pure), and Dorothy (sane).

Answer:

1.2, 3/5, 25%, 0.17, -12

Step-by-step explanation:

In order to put these from greatest to least, you must put these in like terms.

Since there are more decimals that other terms, we're going to convert them all to decimals.

25%= 0.25

0.17= 0.17

3/5= 0.60

1.2= 1.20

-12= -12.00

Now that we see which numbers are greater, we convert them back to their original terms and place them in order from greatest to least.

1.2, 3/5, 25%, 0.17, -12

Answer:

the answer is b. stretch.

Step-by-step explanation:

the side measure 4 is the same for the image as it is for the pre-image. the side measure 8 on the pre-image is 6 for the image. when only one measure changes its a stretch.

The figures' transformation maps the pre-image to the image is stretch .

The original shape of the object is called the Pre-Image and the final shape and position of the object is the Image under the transformation.

According to question

Length of 1st figure = 8

Width of 1st figure = 4

Length of 2nd figure = 6

Width of 2nd figure = 4

as we can conclude that only length is change not breath

that means it is stretch .

Hence, Figures' transformation maps is stretch .

Answer:

The perimeter of the parallelogram is 36 inches.

Step-by-step explanation:

The perimeter of a parallelogram is the addition of all of its side lengths.  In a parallelogram, each side length is repeated twice.  The perimeter can thus be represented by the following formula:

P = length + length + width + width

Now, we can substitute in the values that we are given in the problem.

P = 11 + 11 + 7 +7

Next, we simply have to add together the remaining values to simplify.

P = 36 inches

Therefore, the perimeter is 36 inches.

Step-by-step explanation:

We can subtract both sides of the equation by 3, getting 3 + p - 3 = 8 - 3.

Then we can evaluate, getting p = 8 - 3 = 5.

Answer: 5

Ok, this is just simple math problems think of it like this....

3+p=8 ➡ rearrange the equation

p= 8 - 3 ➡ this is because p has to be added to 3 to make 8

Answer:

243 cm³

Step-by-step explanation:

A cube has the same measure in length, width and height. So, we know that the area of the top face of a cube is 9 square centimeters, this means that

Length x width = 9 square centimeters

But, since length and width are the same, we have that they are equal to [tex]\sqrt{9} =3[/tex] cms (since 3² = 9).

Thus, the volume of each cube is 3³ = 27 cm³

We are going to use 9 of these cubes to make a rectangular prism, therefore, the volume of this prism is going to be 9 times the volume of each cube.

Volume of prism = 9 (27) = 243 cm³

PROBLEM SOLVING WITH PERCENTS: You are planning a wedding reception for 75 guests that will take place in exactly 10 months. There are two different sites that you are contemplating using, with the stipulations on payments as described below. Determine the TOTAL cost of renting each location.

Rental of space = $68 per guest; Down payment = 25% of total cost; Payment due one month before the reception includes a 7.4% interest payment on the balance.

Answer:  Total Cost of Renting = $5312.29

Step-by-step explanation:

Given that;

Rental space = $68 per guest, down payment = 25%,  7.4% interest payment on the balance.

Total Cost of Renting = Down Payment + Remaining payment

Total Cost of Renting = $68 × Guests × 25% + ($68 × Guest - Down payment) ×  (1 + Interest *9/12)

Total Cost of Renting = $68 × 75 × 25% + ($68 × 75 - Down payment) × (1 + 7.40% × 9/12)

Total Cost of Renting = $1275 + ($5100 - 1273) × (1.0555)

Total Cost of Renting = $1275 + 4037.29

Total Cost of Renting = $5312.29
