180÷(4+16)-8×3+7×(2+3)​

Answers

Answer 1

Answer:

111

Step-by-step explanation:

Use PEMDAS to solve this equation, so first we have to do parenthesis first. Simplify 4+16 to get 20. Simplify 2+3 to get 5. Therefore, the equation will now look like 180/(20)-8x3+7x(5). Because we can do either division or multiplication first, we have to solve the equation started from the left. Therefore, we do 180/20 which is 90. Then the equation will be 90-8x3+7x5. Multiply -8 and 3 together to get -24. Therefore, the equation will be 90-24+7x5. Because we always do multiplication/division before addition/subtraction. We have to do 7x5 which is equal to 35. Therefore, the equation will look like 90-24+35. Because there is only subtraction and addition now, we should start from the left hand side which is 90-24. Simplify this to get 76. Then the equation will be 76+35. Simplify this to get 111.

Write the equation that is parallel to the question: y = -2/3x - 5 and goes through point: (6,-1)

Answers

Answer:

y = -2/3x + 3

Step-by-step explanation:

Parallel lines have the same slope so we already know

y = -2/3x + b

Solve for b using the point given

-1=-2/3(6)+b

-1+4=b

b=3

y = -2/3x + 3

Solve the following equation for "y": 3x-4y=20

Answers

Answer:

Step-by-step explanation:

20=3x-4y, add 4y to each side

4y+20=3x, subtract 20 from each side

4y=3x-20, divide each side by 4

y=(3x-20)/4 or if you prefer

y=0.75x-5

Find the arc length along a circle of radius 10 subtended by an angle of 215 degrees

Answers

Answer:

arc = 25.29

Step-by-step explanation:

first find the circumference:

C = 2r(Pi) = 2(10)(3.14) = 62.8

since subtended, then we're looking for these opposite angle of 215 degrees:

360 - 215 = 145 degrees

62.8/360 = 0.1744 per degree

0.1744 x 145  = 25.29

Step-by-step explanation:

Answer:

133°

Step-by-step explanation:

If we assume the the given to adjacent lines to be parallel then ,

The x and supplement of 47° will be equal since they will be corresponding angles .

Therefore :-

=> x = 180° - 47°

=> x = 133° .

Hence the size of angle X is 133°

WILL MARK BRAINLEIST HELPP PLEASEEEE

Answers

the answer is x=15. pls give me brainliest :)

Answer:

15

Step-by-step explanation:

9x + 25 + x + 5 = 180

Add numbers = (25 + 5 = 30)

9x + 30 + x = 180

Combine like terms = (9x + x = 10x)

10x + 30 = 180

Subtract 30 from each side (10x + 30 - 30 = 180 - 30)

10x = 150

Divide 10 from each side (10x/10 = 150/10)

x = 15

Can someone please help me

Answers

Answer:

x = 20

y = 12

Step-by-step explanation:

opposite angles are congruent so we can set up this equation:

5x + 29 = 7x - 11

29 = 2x - 11

40 = 2x

x = 20

5(20) + 29 = 129

7(20) - 11 = 129

3y + 15 = 5y - 9

15 = 2y - 9

24 = 2y

y = 12

3(12) + 15 = 51

5(12) - 9 = 51

If the area of a rectangle is (15x2 - 16x - 15) square feet, and its length is (3x - 5) feet, find its width

Answers

Answer:

255

Step-by-step explanation:

(15x2 - 16x - 15) = 270

(3- 5) = -15

 270

-  -15

= 255

The breadth of the rectangle is (-5x-3).

Area of rectangle

The area of a rectangle is given as the product of its length to its breadth.

[tex]\rm{Area\ of\ Rectangle = Length \times breadth\\[/tex]

Given to us

area of a rectangle = (15x2 - 16x - 15)

length = (3x - 5)

Width

[tex]Area\ of\ Rectangle = Length \times breadth\\(15x^2-16x-15)=(3x-5)\times breadth\\\\(3x-5)\times breadth=(15x^2-16x-15)\\\\breadth = \dfrac{(15x^2-16x-15)}{(3x-5)}\\\\breadth = (-5x-3)[/tex]

Hence, the breadth of the rectangle is (-5x-3).
