Answer:

u = -3

Step-by-step explanation:

-9 - 4u = -u

    +4  = +4

Add 4u to both sides.

-9 = 3u

Divide both sides by 3

-9/3 = 3/3

-3 = u

Answer: The variable u  is equal to -3 for this equation.

Step-by-step explanation:

To solve this variable equation, you will need to follow these steps:

Rewrite the equation, moving 9 to the other side, adding it on both sides, and simplify

-4u = -u + 9

After that, move u to the other side of the equation, also adding it on both sides and simplify

-3u = 9

Then divide both sides by -3, simplify it one last time and you will get your answer!

-3

Therefore, the answer to this equation would be equal to negative three or -3. Hope this helps!

Answer:

The dimensions of the rectangular building are 30 meters by 37 meters.

Answer:

30 by 37 meters

Step-by-step explanation:

Refer to the attached image to understand where the following formulas came from.

[tex]\text{Area,} \ A=1110 \ m^2\\\\\text{Perimeter,} \ P=134 \ m[/tex]

We have a system of equations

[tex]\Longrightarrow \left \{ {{xy=1110} \atop {2x+2y=134}} \right.\\\\\text{Taking equation 2} \rightarrow 2x+2y=134\\\\\Longrightarrow 2x=134-2y\\\\\Longrightarrow x=67-y \\\\\text{Now taking equation 1} \rightarrow xy=1110\\\\ \Longrightarrow (67-y)y=1110\\\\ \Longrightarrow 67y-y^2=1110\\\\ \Longrightarrow y^2-67y+1110=0\\\\\Longrightarrow (y-37)(x-30)=0\\\\\Longrightarrow \boxed{y=37 \ m \ or \ 30 \ m }[/tex]

When y=37:

[tex]x(37)=1110\\\\\Longrightarrow \boxed{x=30}[/tex]

When y=30:

[tex]x(30)=1110\\\\\Longrightarrow \boxed{x=37}[/tex]

So, the dimensions of the building are 30 by 37 meters.

Question 1)

Volume of Tank A = Sum of volume of its two parts.

So,

Volume of Tank A = 24 + 96 = 120 cubic feet

Question 2)

Volume of Tank B and Tank A is the same. So, Volume of Tank B = 120 cubic feet

One section of Tank B = 45 cubic feet

So, volume of other section of tank B = 120 - 45 = 75 cubic feet

hope this helps sorry

The ratio of the volume of the smaller tank compared to the volume of the larger tank is 1/27. Option B is correct.

Ratio of the volume of the smaller tank compared to the volume of the larger tank = Volume of smaller tank/Volume of larger tank.

Volume of cube = a³

a = length of side of cube.

Length of the side of the smaller tank = 15cm.

Length of the side of the larger tank = 45cm.

Volume of smaller tank = (15)³ = 3375 cm³

Volume of larger tank = (45)³ = 91125 cm³

Ratio of the volume of the smaller tank compared to the volume of the larger tank = 3375/91125 = 1/27.

Therefore the ratio of the volume of the smaller tank compared to the volume of the larger tank is 1/27.

Answer:1/8

Step-by-step explanation:

Answer:

Step-by-step explanation:

To solve the congruence 5x ≡ 6 (mod 7), we need to find a value for x that satisfies the equation.

First, we'll find the multiplicative inverse of 5 modulo 7. The multiplicative inverse of a modulo m is a number x such that ax ≡ 1 (mod m). In this case, we need to find a number x such that 5x ≡ 1 (mod 7).

To find the multiplicative inverse, we can try different values of x and compute the result until we find one that satisfies the equation. Alternatively, we can use a more efficient method like the Extended Euclidean Algorithm.

Using the Extended Euclidean Algorithm, we find that the multiplicative inverse of 5 modulo 7 is 3, as 5 * 3 ≡ 1 (mod 7).

Now, we can multiply both sides of the congruence by the multiplicative inverse (3) to isolate x:

5x ≡ 6 (mod 7)

3 * 5x ≡ 3 * 6 (mod 7)

15x ≡ 18 (mod 7)

Reducing the coefficients:

1 * x ≡ 4 (mod 7)

Since x ≡ 4 (mod 7), the solution to the congruence 5x ≡ 6 (mod 7) is x ≡ 4 (mod 7). This means that x can be written as x = 4 + 7k, where k is any integer.

Answer:

Step-by-step explanation:

The expression without the absolute value symbol is:

|x - 8| = x - 8, if x > 8

|x - 8| = 0, if x = 8

|x - 8| = 8 - x, if x < 8

From the given parameters

We have,

|(x - 19) + 11|

This can be written as,

= |x - 19 + 11|

= |x - 8|

Now,

|x - 8| = x - 8, if x > 8

|x - 8| = 0, if x = 8

|x - 8| = 8 - x, if x < 8

Thus,

The expression without the absolute value symbol is:

|x - 8| = x - 8, if x > 8

|x - 8| = 0, if x = 8

|x - 8| = 8 - x, if x < 8

Answer:

c and a

Step-by-step explanation:

Part A: 15x= $810.75. Part B: x= $54.05

The total money earned from 15 tickets is $810.75.

Assume, the money earned from selling 1 ticket is $x.

Therefore, the money earned from selling 15 tickets= 15*x= 15x= $810.75

Here, the variable, i.e. the changing value, is x which is the price of each ticket. The equation hence derived is 15x= $810.75.

Using the equation above,

15x= $810.75.

Dividing both sides by 15,

We get,

x= $54.05

Hence, $54.05 is the price of each ticket.

Mario

Step-by-step explanation:

Sheila has a 5 dollar allowance and saved for 3 weeks. 3 x 5 = 15 dollars saved total. She spends 9 of the 15. 15 - 9 = 6, so Sheila donated 6 dollars.

Mario has a 4 dollar allowance and saves for 4 week. 4 x 4 is 16 dollars saved. He then spends 8 of them, 16 - 8 = 8 dollars donated.

Gina has a 6 dollar allowance and saves for 4 weeks. 6 x 4 is 24. She then spends 17 dollars. 24 - 17 is 7 dollars donated.

Sheila donates 6 dollars. Mario donates 8 dollars. Gina donates 7 dollars.
Out of the three, Mario has donated the most.

Subtract 6z from both sides.

-2 = 6 + 4z

Subtract 6 from both sides.

-8/4 = 4z/4

Answer:

First box (Top left): y + x = 4

Second box (Top right): y = x + 4

Third box (Bottom): y = (1/4)x

Step-by-step explanation: For the first box on the top left, the line is shown going down which means as x increases, y decreases resulting in a negative slope. Since the equation of a line has the form y = mx + b where m represents the slope, m would be a negative number for a negative slope. By rearranging the equations above, we can write y + x = 4 as y = -x + 4 after subtracting both sides by -x to make it look like the form y = mx + b. Since this is the only equation with a negative slope and the y-intercept (where the line intercepts the y-axis) represented as b is 4 as shown in the graph and the equation, the equation for this line is y + x = 4.

For the second box on the top right, the line is shown going up which means as x increases, y increases resulting in a positive slope. Since the slope is now positive, the m, in the same form, y = mx + b, would be a positive number. The y-intercept or b is also still 4 as shown in the graph as the line intersects the y-axis so by looking at the options above, the equation for this line is y = x + 4.

For the third box on the bottom, the line is shown with a less steep slope going up meaning as x increases, y increases with a lower slope. Since the slope will still be positive but lower than the previous line with a y-intercept of 0 as shown in the graph, the equation for this line is y = (1/4)x.

Answer:

5c/4

Step-by-step explanation:

c = c × 1

0.25c = 0.25c × 1

c + 0.25c

Take " c " common.

= c × (1 + 0.25)

= c × 1.25

Convert 1.25 into a simpler fraction

1.25

= 125/100

= 5/4

c × 1.25

= c × 5/4

= (c × 5)/4

= 5c/4

The fractional coefficient is (5c/4)

A coefficient is a number or any symbol representing a constant value that is multiplied by the variable of a single term

Given:

[tex]\sf c+0.25c[/tex]

[tex]\sf =(1+0.25)c[/tex]

[tex]\sf =(1.25)(c)[/tex]

[tex]\sf =1.25c[/tex]

[tex]\sf =\dfrac{125}{100}[/tex]

[tex]\sf =\dfrac{5}{4}[/tex]

[tex]\sf =\dfrac{5c}{4}[/tex]

Hence the fractional coefficient is (5c/4)

To compare the probabilities of hitting the ball, we need to find the decimal equivalent of each fraction.

Player 1: 7/11 = 0.636

Player 2: 6/9 = 0.667

Player 3: 5/7 = 0.714

Comparing the probabilities, we can see that Player 3 has the highest probability of hitting the ball, followed by Player 2 and then Player 1. So the correct statement is:

Player 3 is more likely to hit the ball than Player 2 because P(Player 3) > P(Player 2), and Player 2 is more likely to hit the ball than Player 1 because P(Player 2) > P(Player 1).

It's important to note that the probabilities don't guarantee that a player will hit the ball every time they're at bat. They simply indicate the likelihood of hitting the ball based on their past performance.
