x=24
Step-by-step explanation:
Hello There!
Angle E and angle D are supplementary angles meaning that the sum of the two angles equals 180
So we setup an equation
180=2x+12+5x
step 1 combine like terms
5x+2x=7x
now we have
180=7x+12
step 2 subtract 12 from each side
12-12 cancels out
180-12=168
now we have
168=7x
step 3 divide each side by 7
7x/7=x
168/7=24
we're left with~ x=24

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

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

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

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