15 Points Do All Thanks Please Do All

Answer 1
For the first one you plug the second equation into the first so substitute the y with x + 7 so you have -6x-5(x+7)=9 and you get -11x-35=9 and then you have -11x=44 and so x=-4 and the you plug -4 into y = x+7 and so y would be 3.

The next question you can turn -7p-35 to -7(p+5) and then cancel out the -7 on both sides and get p+5=3p-3 and then you -p and +3 both sides and get 2p=8 and so p = 4

you can plug the numbers just to double check

|-13\ = -(-13)
True False?

Answers

Answer:

This statement is true.

Step-by-step explanation:

The absolute value is how far the number is from zero, so how many steps will it take on a number line to get from that particular number to zero?

Since you can't have negative steps, The -13 in absolute value would be 13.

The -(-13) is the same thing as saying  -1 ( -13 ). Since negative times a negative is a positive, 13=13 is a true statement.

Jean's eye level is 1.5 meters off the ground. When he stands 430 meters from the base of the Eiffel Tower, he must tilt his head up by 36° to see the top of the tower. Based on this, how tall is the Eiffel Tower? Round to one decimal place, if necessary, and include units in your final answer. SHOW WORK

Answers

Answer:

313.9 m

Step-by-step explanation:

tan 36° = opp/adj

tan 36° = y/430

y = 430 tan 36°

y = 312.4

height = 1.5 + 312.4 = 313.9

Answer: 313.9 m

Answer:

313.9

Step-by-step explanation:

First use  trigonometric ratio of tan   .

consider the angle to be  36 .

base of the triangle to be 430  .

consider the perpendicular to be the height of the tower from the eye level of Jean to the top.  let's take it is   x  

the formula will be      tan  36  = x /430

find x  by using  tan  36    =  0.73   and multiplying this by  430  

it will be 312.4

adding the height of jean  1.5     .

total height of the tower is     313.9  

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

Please I need help

Answers

Answer:

m=-7/2

Step-by-step explanation:

 (5 • (m + 2) -  m) -  (2m + 3)  = 0

 2m + 7  = 0

3.1      Solve  :    2m+7 = 0

Subtract  7  from both sides of the equation :

                     2m = -7

Divide both sides of the equation by 2:

                    m = -7/2 = -3.500

Answer

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

5m+10-m=2m+3

5m-2m-m=-10+3

3m-m=-10+3

2m=-7

m= -7/2

m= -3.5

Answer: The area of the shaded region is 30 cm^2

Step-by-step explanation:

First, we recall the area for a rectangle and a triangle.

-Area for rectangle: A = L x W

-Area for triangle: A = 1/2 x b*h

Next, I find the area of the total region.

-12 cm x 4 cm = 48 cm^2

Then, I find the area for the non-shaded region (or the white triangle)

- A= 1/2 x 9*4

- A= 1/2 x 36

- A = 18 cm^2

Finally, I subtract the total area of the whole region from the non-shaded region ( or again white triangle)

- 48 minus 18 = 30 cm ^2

if i buy 2 chicken and 3 boxes of stuffing how much change will i get from 20 pound ? chicken is £2.65 sage onion stuffing is £1.15 per box

Answers

Answer: 11.25

So first you would do 2 x 2.65 to find the price of the chicken which is 5.3 so next we find the price of the stuffing 3x1.15 which is 3.45 so then we add them 5.3+3.45=8.75 so then we subtract that from 20 so 20-8.75 so our change is 11.25

2(12+x) = 2x=24 simplify and show work

Answers

2x = 24
—. —
2. 2

24 divided by 2 = 12

x = 12

Answer:

No possible answer (unless the equal sign was supposed to be a plus sign, then see answer below)

Step-by-step explanation:

we can simplify the expression like such:

24 + 2x = 2x = 24

As you will notice 2x + 24 cannot equal 2x, or 24.

If the equals sign was a typo and was meant to be a plus sign then the answer is all real numbers.

2(12 + x) can be broken down to (2*12) + (2*x) which equals 2x + 24.

Then this equals the other side of the equation meaning that it doesn't matter what x equals the equation is always equal.
