8x-5(4x+3)-(3-2x)=4-4(2x-3)-(9-3x)

Mathematics
1 answer:
dusya [7]3 years ago
8 0

Answer:

x=-5

Step-by-step explanation:Step 1: Simplify both sides of the equation.

8x−5(4x+3)−(3−2x)=4−4(2x−3)−(9−3x)

8x−5(4x+3)+−1(3−2x)=4−4(2x−3)+−1(9−3x)(Distribute the Negative Sign)

8x+−5(4x+3)+(−1)(3)+−1(−2x)=4+−4(2x−3)+(−1)(9)+−1(−3x)

8x+−5(4x+3)+−3+2x=4+−4(2x−3)+−9+3x

8x+(−5)(4x)+(−5)(3)+−3+2x=4+(−4)(2x)+(−4)(−3)+−9+3x(Distribute)

8x+−20x+−15+−3+2x=4+−8x+12+−9+3x

(8x+−20x+2x)+(−15+−3)=(−8x+3x)+(4+12+−9)(Combine Like Terms)

−10x+−18=−5x+7

−10x−18=−5x+7

Step 2: Add 5x to both sides.

−10x−18+5x=−5x+7+5x

−5x−18=7

Step 3: Add 18 to both sides.

−5x−18+18=7+18

−5x=25

Step 4: Divide both sides by -5.

−5x −5 = 25 −5

x=−5

A student stands 20 m away from the foot
Ostrovityanka [42]

Answer:

Height of tree is \approx <em>15 m.</em>

<em></em>

Step-by-step explanation:

Given that student is 20 m away from the foot of tree.

and table is 1.5 m above the ground.

The angle of elevation is: 34°28'

Please refer to the attached image. The given situation can be mapped to a right angled triangle as shown in the image.

AB = CP = 20 m

CA = PB = 1.5 m

\angle C = 34°28' = 34.46°

To find TB = ?

we can use trigonometric function tangent to find TP in right angled \triangle TPC

tan \theta = \dfrac{Perpendicular}{Base}\\tan C= \dfrac{PT}{PC}\\\Rightarrow tan 34.46^\circ = \dfrac{PT}{20}\\\Rightarrow PT = 20 \times 0.686 \\\Rightarrow PT = 13.72\ m

Now, adding PB to TP will give us the height of tree, TB

Now, height of tree TB = TP + PB

TB = 13.72 + 1.5 = 15.22 \approx <em>15 m</em>

Find the value of x?
jekas [21]
Hello!
The left triangle have two same side length so the two bottom angles are the same which is (180-56)/2=62
See the left triangle bottom right angle and the right triangle bigger angle have the sum of 180 degree so the bigger angle=180-62=118
The right triangle also have two same sides so they also have same angle degree so x=(180-118)/2=31
Have a great day!
