2 (x + 3 )= -x⁣

Answers

Answer:

-2 =x

Step-by-step explanation:

2 (x + 3 )= -x⁣

Distribute the 2

2x+6 = -x

Subtract 2x from each side

2x+6-2x = -x-2x

6 = -3x

Divide each side by -3

6/-3 = -3x/-3

-2 =x

Answer:

x = -2

Step-by-step explanation:

2 (x + 3) = -x

2x + 6 = -x

    - 6     -6

2x = -x - 6

Complementary Angles: The angle with 32˚ and 48˚

Supplementary Angles: The angle that is together with the angles of 107˚ and 73˚

Neither: The angle with 101˚ and 77˚ since

Step-by-step explanation:

Complementary angles are angles that sum up to 90˚ so 32 plus 48 is 90 which makes it a complementary angle.

Supplementary angles are angles that sum up to 180˚ so 107+73 is 180 which makes it a supplementary angle.

To find the angle with "neither" Complementary nor Supplementary you use the process of elimination

Ryan buys some jumpers to sell on a stall. He spends £130 buying 80 jumpers. He sells 75% of the jumpers for £9 each. He then puts the rest of the jumpers on a Buy one get one half price offer. He manages to sell half the remaining jumpers using this offer. How much profit does Ryan make?

Answers

Answer:

£477.5

Step-by-step explanation:

According to the problem, calculation of given data are as follows,

Total jumper bought = 80

Total spends = £130

Now, first sell 75% of jumper for £9 each, then

75% × 80 = 60

So, 60 × £9 = £540

Remaining jumper = 80 - 60 = 20

Selling half of remaining, 20÷ 2 = 10

Selling 10 jumper = (5 × £9) + (5 × £4.5 ) ( buy one get one half price)

Income of 10 = £45 + £22.5 = £67.5

So, total income by selling 70 jumpers = £540 + £67.5 = £607.5

Hence, Profit = £607.5 - £130

= £477.5

A chocolate pastry cost Rs.26 and a fruit pastry cost Rs.18 Jenny buys both
these pastries together for Rs. 500 how many of each did she buy ?

Answers

Required Answer:-

Let's assume the no. of chocolate pastry bought = x

and the no: of fruit pastry bought = y

➣ Cost of 1 chocolate pastry = Rs 26

➣ Cost of x chocolate pastry = Rs 26x

➣ Similarly, cost of fruit pastry = Rs 18 y

➣ It is given that the total cost = Rs 500

Therefore, Rs 26x + Rs 18 y = Rs 500

If we assume x = 4 and y = 22 , then

26 x 4 + 18 X 22 = Rs 500

104 + 396 = 500

⇝ No. of chocolate pastries bought = 4 ✔

⇝ No. of fruit pastries bought = 22 ✔

The missing dimension of the prism is A

because the volume of the rectangular prism equals the product of the sides, we have:

V = (x - 1)(x - 3)A

but V = x³ - 8x² + 19x - 12

=> x³ - 8x² + 19x - 12 = (x - 1 )(x - 3)A

⇔ x²(x - 1) - 7x(x - 1) + 12(x - 1) = (x - 1)(x - 3)A

⇔ (x² - 7x + 12)(x - 1) = (x - 1)(x - 3)A

⇔ (x² - 3x - 4x + 12)(x - 1) = (x - 1)(x - 3)A

⇔ (x - 3)(x - 4)(x - 1) = (x - 1)(x - 3)A

⇒ A = x - 4

A 13 feet ladder is placed 5 feet away from a wall. The distance from the ground straight up to the top of the wall is 13 feet Will the ladder the top of the wall?

Answers

Answer:

the answer is

a^2 + b^2 = c^2

5^2 + b^2 = 13^1

25 + b^2 = 169

b^2 = 144

b = 12  

or

The ladder is the hypotenuse, and the two legs are distance from the wall and height of the wall. If it is moved 5 feet away, it will reach 12 feet high, for 5^2+12^2=13^2.

The width of a rectangle is the length minus 6 units the area of the rectangle is 27 units

Answers

Answer:

length = 9 units

Step-by-step explanation:

l = length

n - 6 = width

A = n(n - 6)

A = n² - 6n

27 = n² - 6n

n² - 6n - 27 = 0

(n + 3)(n - 9) = 0

n = -3, n = 9

length must be 9 because it cannot be a negative value

g(x) = -10x2 + 490
lesser =
greater x =

Answers

Answer:

Lesser = -490

Greater x = 100x

Step-by-step explanation:

The zeros is basically the opposite numbers to make the equation equal to 0.

We have -10x^2(I believe it's a power)

and we have + 490

so,

-10x^2 = -100x

So the opposites to make those is:

+ 100x because, -100x + 100x = 0

and -490 because, 490 - 490 = 0.
