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

I need help with these two questions
Mandarinka [93]

Answer:

(-2,-2)

Step-by-step explanation:

for question number 15...cordinated grid shows each equation...first equation is represented by straight line going upwards through +4 in y axis...(y=3x+4)...

point is....every point in this two lines represent a possible x and y value for each equation...and there is a point where these lines meet each other....in that point...x and y values are possible values for both equations.so answer is (-2,-2)...this cordination satisfy each pairs of equation...you can try using -2 for x in both equations and get -2 as the answer for y...that proves the point..try it for 16 quiz.good luck

Devin purchased tickets to an air show for eight adults and two children The total cost was $140 and the cost of a child’s ticke
My name is Ann [436]

Answer:

The answer is: The adult ticket costs $15 and the child ticket costs $10.

Step-by-step explanation:

Let a = the dollar amount of adult tickets and c = the dollar amount for child tickets. The child ticket cost $5 less than the adult ticket. Then:

c = a - 5

The number of adult tickets times the adult cost plus the number of child tickets times the cost for child tickets is equal to the total dollar amount. Set up the equation:

8a + 2c = $140

Substitute:

8a + 2(a-5) = 140

8a + 2a - 10 = 140

10a = 150

a = 150 / 10 = 15, so the adult ticket is $15

Solve for c:

c = a - 5

c = 15 - 5 = 10, so the child ticket is $10

Proof:

8a + 2c = 140

8(15) + 2(10) = 140

120 + 20 = 140

140 =140

The coach of Esther's soccer team always gives the team a few options for the warm-up before practice. The option for today is t
Svetradugi [14.3K]

The option that will give Esther the greatest distance will be option 6.

<h3>How to calculate the distance?</h3>

Based on the information given, AC will be:

= ✓(125)² + (85)2

= 151.16m

The distance covered in 6 diagonal runs will be:

= 6 × 151.16

= 906.97m

The distance covered in 7 diagonal runs will be:

= 7 × 125

= 875m

Therefore, the option that will give Esther the greatest distance will be option 6.
