Answer:

for 20 number.

<AEB=142

<BEC=38

<DEC=142

<AED=38

Step-by-step explanation:

or, m<AEB+m<BEC=180(Straight line)

or, 6x-32+2x-20=180

or, 8x-52=180

or, x=29

replacing value of x

m<AEB=6×-32

=6*29-32

=142

m<BEC=2X-20

=2*28-20

=38

m<AED=m<BEC=38(Vertcally opposite angle)

m<DEC=m<AEB=142(Vertically opposite angle)

Which equation of a line contains the points (-10,15) and (8, -3) and is parallel to y +4= -(x - 1)?

JulijaS [17]

Answer:

y= -x+5

Step-by-step explanation:

The slope of the two parallel lines is equal

so, the slope of

y=-x-3 is -1

slope=y2-y1/x2-x1=-3-15/8--10=-1

the equation of the line is

y-15= -1(x--10)

y= -x-10+15

y= -x+5

Solve x - 3 1/8 = 5/12

Anna007 [38]

Answer:

$\large\boxed{x=\dfrac{85}{24}=3\dfrac{13}{24}}$

Step-by-step explanation:

Convert the mixed number to the fraction:

$3\dfrac{1}{8}=\dfrac{3\cdot8+1}{8}=\dfrac{25}{8}$

METHOD 1:

$x-3\dfrac{1}{8}=\dfrac{5}{12}\\\\x-\dfrac{25}{8}=\dfrac{5}{12}\\\\\text{the common denominator is 24}\\\\x-\dfrac{25}{8}=\dfrac{5}{12}\qquad\text{multiply both sides by 24}\\\\24x-(3)(25)=(2)(5)\\\\24x-75=10\qquad\text{add 75 to both sides}\\\\24x=85\qquad\text{divide both sides by 24}\\\\\boxed{x=\dfrac{85}{24}}$

METHOD 2:

$x-3\dfrac{1}{8}=\dfrac{5}{12}\qquad\text{add}\ 3\dfrac{1}{8}\ \text{to oboth sides}\\\\x=\dfrac{5}{12}+3\dfrac{1}{8}\\\\x=\dfrac{5\cdot2}{12\cdot2}+3\dfrac{1\cdot3}{8\cdot3}\\\\x=\dfrac{10}{24}+3\dfrac{3}{24}\\\\x=3\dfrac{10+3}{24}\\\\\boxed{x=3\dfrac{13}{24}}$

Three-fifths is how many pieces of the whole.

Degger [83]

If you cut the "whole" into 5 equal pieces, then 3/5ths would be 3 of those 5 pieces. so the answer is 3

There are 165 counters in a bag. Each counter is either black or white.

Nostrana [21]

6:5

there are 165 counters in the bag.

let the white counter be x

the black counter = 2x

2x + x = 165

3x=165

divide both sides by 3

x=55

there are 55 white counters in the bag

165-55=110

2x= 165

divide both sides by 2

x= 110

there are 110 black counters in the bag
Martine takes 40%of the black counter

40%= 40/100×110

= 44.

44 black counters was taken out of the bag
then there would be 66 black counters left I.e(110-44=66)

▪︎ there would be 66 black and 55 white counters in the bag.

ratio of black counters to the white counter = 66:55
reduced to the lowest term = 6:5 ( 11 divides 66 and 55 Into 6 and 5)

• the answer is 6:5
