what is 57÷3 1/3 I need this asap please

Answers

First we need to turn 3 1/3 into an improper fraction:

3 1/3 = 10/3

Because we are dividing, multiply 57 my the reciprocal (the faction flipped upside down) of 10/3:

57 x 3/10

Which can also be written as:

57/1 x 3/10

Now we just multiply:

171/10

Therefore 171/10 is ur answer

Given a
rectangle of area 18x2 - 42x, the length is 6x, determine the width. HELP

Answers

Rectangle area = length * width
18x^2-42x=6x*width
Width = (18x^2-42x)/6x
Width = 3x-7

Let’s make sure
Area = length * width
Area = 6x * (3x-7)
Area = 18x^2 -42x which is true
That mean width = 3x-7

Find the shaded area of each figure, round your answer to one decimal place if necessary

Answers

area of shaded portion = 49.5 yd²____________________

Step-by-step explanation:

radius of circle = 5 yd ------ ( given )

height of triangle = 16 yd --- ( given )

base of triangle = 16 yd ----- ( given )

area of triangle = 1/2 × base × height

= 1/2 × 16 × 16

= 128 yd²

area of circle = π × radius²

= 3.14 × 5 × 5 --- ( π = 3.14 )

= 78.5 yd²

---------------------------------------

area of shaded portion = area of triangle - area of circle

area of shaded portion= 128 yd²-78.5 yd²

area of shaded portion = 49.5 yd²

Answers

Answer:

A= 3,B = 2

Hope it helps you

if yes mark me brainliest

Answer:

hence, a = 3

b = 2

Step-by-step explanation:

from the given pair of linear equation we get,

7a + 3b = 27 - ( 1 )

6a + 3b = 24 - ( 2 )

now, subtract equation 2 from equation 1

=》7a + 3b - 6a - 3b = 27 - 24

=》a = 3

now put the value of a in equation 1

=》7a + 3b = 27

=》( 7 × 3 ) + 3b = 27

=》21 + 3b = 27

=》3b = 27 - 21

=》b = 6 ÷ 3

=》b = 2
