Answers

Answer:

x=2

Step-by-step explanation:

4(x-1) = 2(6-2x)

x=2

Answer:

x=2

Step-by-step explanation:

4(x-1)=2(6-2x)

4x-4=12-4x

Add 4 to both sides

4x=16-4x

Add 4x to both sides

8x=16

Divide by 8 on both sides

The tape diagram represents the ratio of the numbers of planets in two different solar systems. There are 8 planets in Solar System B. How many planets are in Solar System A?

Answers

The correct answer is 6 planets

Explanation:

The image presented shows the ratio of planets in solar system A vs those in solar system B. In this way, the general ratio is 3 : 4 or 3 to 4; this means for each 4 four planets in solar system B there are 3 planets in solar system A and vice versa. Now, to find the total of planets in system A if there are 8 planets in system B, follow this process:

8 planets / 4 = 2 planets - This means each of the sections in the diagram represents 2 planets

2 section x 3 = 6 planets as in the solar system A there are 3 sections and each of this represents 2 planets, the total of planets in this system are 6

This result can also be found by converting the ratio to a fraction and multiplying this by the 8 planets

8 planets x [tex]\frac{3}{4} = \frac{24}{4} = 6[/tex]

A ladder is placed against a wall such that the top is 8 feet above the ground. If the ladder is 10 feet long, how far away from the wall is the base of the ladder

Answers

Answer:

6 feet

Step-by-step explanation:

Consider the right triangle formed by the wall, ladder and ground.

Let the distance the ladder is from the wall be d , then

Using Pythagoras' identity in the right triangle

The square on the hypotenuse ( ladder) is equal to the sum of the squares on the other 2 sides ( wall and d ), then

d² + 8² = 10²

d² + 64 = 100 ( subtract 64 from both sides )

d² = 36 ( take the square root of both sides )

d = [tex]\sqrt{36}[/tex] = 6

That is the ladder is 6 feet away from the wall

Answer:

y ≥ -2x +1y ≤ 2x +4

Step-by-step explanation:

The downward-sloping line has a y-intercept of 1 and a slope of -2, so its equation is ...

  y = -2x +1

The graph is shaded on and above that line, so the inequality it represents is ...

  y ≥ -2x +1

__

The upward-sloping line has a y-intercept of +4 and a slope of +2, so its equation is ...

  y = 2x +4

The graph is shaded on and below that line, so the inequality it represents is ...

  y ≤ 2x +4

Then the system of inequalities is ...

  y ≥ -2x +1

  y ≤ 2x +4

Deon throws a ball into the air. The height h of the​ ball, in​ meters, at time t seconds is modeled by the function ​h(t)=-5t^2+14t+3 When will the ball hit the​ ground

Answers

Answer:

The time the ball will hit the ground is 1.4s

Step-by-step explanation:

Given;

function of the ball's motion; h(t)= -5t²+ 14t + 3h

The final velocity of the ball, v , is given as;

v = dh/dt

v = -10t + 14

When the ball hits the​ ground, the final velocity, v = 0

v = -10t + 14

0 = -10t + 14

10t = 14

t = 14 / 10

t = 1.4s

Therefore, the time the ball will hit the ground is 1.4s

Mr. Myers wants to join a music club. The 1st choice music club charges a $5 sign-up fee and $1 each song. The Superstar music club charges no sign-up fee and charges $3.50 each song.

Answers

Answer:

1st choice Music Equation: [tex]\$(x+5)[/tex]

Superstar Music Club Equation: [tex]\$3.50x[/tex]

Solution: 2

Step-by-step explanation:

Given that:

1st choice music club:

Charges for one song = $1

Charges for sign - up = $5

Let the number of songs = [tex]x[/tex]

Total cost = [tex]\$5+\$1\times x = \$(x+5)[/tex]

Superstar music club:

No sign up fee and

Charges for one song = $3.50

Total cost = [tex]\$3.50x[/tex]

Given that, cost of each music club becomes equal:

Putting them same:

[tex]x+5=3.5x\\\Rightarrow 2.5x = 5\\\Rightarrow \bold{x =2}[/tex]

After 2 songs, the cost of both the clubs will become equal.
