Mathematics
1 answer:
laiz [17]3 years ago

Answer:

x=22

Step-by-step explanation:

we know that

If line l is parallel to line m

then

130\°+(2x+6)\°=180\° -----> by supplementary angles (consecutive interior angles)

solve for x

136+2x=180

2x=180-136

2x=44

x=22

4r^-3 * 2r^2 =

4*(2r^(-3+2))

= 4*2r^-1

= 4*2(1/r)

= 4*(2/r)

=8/r

Identify the expression equivalent to 4(x + x + 7) − 2x + 8 − 4 by substituting x = 1 and x = 2. 6x + 11 3(x + 7) 2(3x + 16) 3x

2(3x+16)

Step-by-step explanation:

Identify the expression equivalent to 4(x + x + 7) − 2x + 8 − 4

4(x + x + 7) − 2x + 8 − 4

When x=1 , the expression becomes 4(1+1+7)-2(1)+8-4=38

When x=2 , the expression becomes 4(2+2+7)-2(1)+8-4=44

Plug in x=1  and check with each expression

6x + 11 =6(1) +11= 16

3(x + 7) = 3(1+7)= 3(8)= 24

2(3x + 16) = 2(3(1)+16)= 38 , we got same answer when x=1, now check with x=2

2(3x + 16) = 2(3(2)+16)= 44

3x + 16= 3+16= 19

Please help with this simple trig problem- angle of two sectors of a circle
igomit [66]

Answer:

  K = (1/2)r^2(sin(θ) +θ)

Step-by-step explanation:

The area of the triangle to the left is ...

  A1 = (1/2)r^2·sin(180°-θ) = (1/2)r^2·sin(θ)

The area of the sector to the right is ...

  A2 = (1/2)r^2θ

so the total area of the blue shaded region is ...

  K = A1 + A2 = (1/2)r^2·sin(θ) + (1/2)r^2·θ

  K = (1/2)r^2(sin(θ) +θ)

Plssssss help me plssssssssss
vodomira [7]

Answer:

x = -1

y = 4

Step-by-step explanation:

i believe this shape is a rhombus because the diagonals are perpendicular and bisectors, meaning m∡A = m∡B = m∡C = m∡D

so AC = CB = BC = DA

y + 1 = 2y - 3

1 = y - 3

4 = y

Plugging in 4 for 'y' means all sides are equal to 5

find x:  2x + 7 = 5

2x = -2

x = -1

Write this fraction as a sum or difference.<br><br> 17. 9p-63
Alex787 [66]
P=7 because when you do bring 63 on the other side it'll be 9p=63 and after that divide both sides by 9 and you'll have p=7
