I need help on these two! Can annoying explain?

Answers

You are solving the two equations for x.

9.

r = 4 + 7x - sx

We need to solve for x. x is only found in the right side. First, just flip the sides to find x only in the left side.

4 + 7x - sx = r

We want all terms with x on the left side, and all terms without x on the right side. Now we subtract 4 from both sides.

7x - sx = r - 4

Factor x in left side.

x(7 - s) = r - 4

Divide both sides by 7 - s.

[tex] x = \dfrac{r - 4}{7 - s} [/tex]

12.

3z + 8 = 12 + 3x - z

Since x is only in the right side, flip the sides.

12 + 3x - z = 3z + 8

We need to isolate x in the left side, so subtract 12 from both sides and add z to both sides.

3x = 3z + 8 - 12 + z

3x = 4z - 4

Divide both sides by 3.

[tex] x = \dfrac{4z - 4}{3} [/tex]

How many weeks until all 350 rhinos disappear?

Answers

A very simple way to solve this specific problem is acknowledging the fact that the left hand side (L.H.S) is being multiplied by a factor of 10 to get the equation on the right hand side (R.H.S). So, if we multiply the denominator by 10, we'll get the answer, which would be 1 × 10 = 10 weeks.

In 1 hour how many more times does a rabbits heart beat than a dogs rabbits heart beat per 1 minute 212 dogs heart beat per 1 minute

Answers

Answer: In  1 hour, 12720 more times rabbit's heart beat than a dog's rabbits heart beat

Step-by-step explanation:

Since we have given that

Rabbit's heart beat in 1 min 212 times more than dog's heart beat in 1 min.

So, in 1 hour , we get,

[tex]1\text{ hour }= 60\text{ minutes}\\so, heartbeat = 212\times 60=12720[/tex]

So, in  1 hour, 12720 more times rabbit's heart beat than a dog's rabbits heart beat .

To determine how many more times a rabbit's heart beats than a dog's in an hour, multiply the rabbit's beats per minute by 60 to get the hourly beat total, and do the same for the dog. Subtract the dog's total from the rabbit's to find the difference. Assuming a dog's heart rate of 70 beats per minute, a rabbit's heart beats 8,520 more times per hour than a dog's.

To calculate how many more times a rabbit's heart beats than a dog's in one hour, we first need to establish the number of beats per hour for both animals. Since the rabbit's heart beat is 212 times per minute, we multiply this number by 60 (the number of minutes in an hour) to find out the total heartbeats in one hour for a rabbit:

Rabbit heartbeats per hour = 212 beats per minute x 60 minutes = 12720 beats per hour.

Next, we need the same figure for the dog. Without the specific heart rate for the dog, we'll assume a generic heart rate for calculation purposes. For example, if a dog's heart beats 70 times per minute (a common rate for dogs), we multiply by 60:

Dog heartbeats per hour = 70 beats per minute x 60 minutes = 4200 beats per hour.

Now, to find out how many more times the rabbit's heart beats than the dog's, we subtract the dog's heartbeats per hour from the rabbit's:

Rabbit's additional heartbeats = 12720 beats per hour - 4200 beats per hour = 8520 more beats per hour.

Brian, Kelsey, and Geoff each have a remote-controlled car. They simultaneously started their cars and drove them in a straight line away from a motion sensor. The sensor recorded the distance to each car in the table below

Answers

The answer is A. This is because you can see Brian's and Kelsey's cars traveled 4 more centimeters every 2 seconds.

Answer:

The correct option is 1.

Step-by-step explanation:

It is given that the Brian, Kelsey, and Geoff each have a remote-controlled car. They simultaneously started their cars and drove them in a straight line away from a motion sensor.

It means they are travelling at a constant rate.

Slope formula:

[tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex]

From the given table it is clear that the of Brian's car from the sensor is 34 at 1 sec and 38 at 3 sec. The rate of change is

[tex]m=\frac{38-34}{3-1}=2[/tex]

It means the Brian's car traveled at the rate of 2 cm per sec.

From the given table it is clear that the of Brian's car from the sensor is 27 at 1 sec and 31 at 3 sec. The rate of change is

[tex]m=\frac{31-27}{3-1}=2[/tex]

It means the Kelsey's car traveled at the rate of 2 cm per sec.

From the given table it is clear that the of Brian's car from the sensor is 27 at 1 sec and 33 at 3 sec. The rate of change is

[tex]m=\frac{33-27}{3-1}=3[/tex]

It means the Geoff's car traveled at the rate of 3 cm per sec.

Since Brian's and Geoff's car traveled at the same rate, therefore option 1 is correct.

T=gr+gvt solve for g

Answers

On the right side, both terms contain g, so we can factor it out


T = g(r+vt)

Now, to get g by itself, divide by the things in parentheses

g= T/(r+vt)



Final answer:

To solve the equation T=gr+gvt for g, you can factor out g from the right side, obtaining T=g(r+vt). Then, dividing both sides by (r+vt) will isolate g, resulting in g = T/(r+vt).

Explanation:

To rearrange the equation T=gr+gvt to solve for g, you need to factor out g from the right side of the equation. Factoring out g, you obtain T=g(r+vt). Dividing by (r+vt) on both sides then gives you the equation for g: g = T/(r+vt).

Here are the steps in detail:

Begin with T=gr+gvt Factor out g from the right side: T=g(r+vt) Divide both sides by (r+vt) to isolate g: g = T/(r+vt)

Twice the smaller of two numbers is one half of the large number. The larger number exceeds three times the smaller number by 10. Find the large number.

Answers

The larger number is 40. Smaller number is 10.

Let's denote the smaller number as [tex]\( x \)[/tex] and the larger number as [tex]\( y \)[/tex].

According to the problem:

1. "Twice the smaller of two numbers is one half of the larger number" can be represented as:

[tex]\[ 2x = \frac{1}{2}y \][/tex]

2. "The larger number exceeds three times the smaller number by 10" can be represented as:

[tex]\[ y = 3x + 10 \][/tex]

Now we can solve this system of equations. Let's start by substituting the second equation into the first:

[tex]\[ 2x = \frac{1}{2}(3x + 10) \][/tex]

Multiplying both sides of the equation by 2 to eliminate the fraction:

[tex]\[ 4x = 3x + 10 \][/tex]

Subtracting [tex]\( 3x \)[/tex] from both sides:

[tex]\[ x = 10 \][/tex]

Now, substitute [tex]\( x = 10 \)[/tex] into the second equation to find [tex]\( y \)[/tex]:

[tex]\[ y = 3(10) + 10 \][/tex]

[tex]\[ y = 30 + 10 \][/tex]

[tex]\[ y = 40 \][/tex]

So, the larger number is [tex]\( 40 \)[/tex].

13 POINTS Since the slope of a vertical line is undefined, is it possible for vertical lines to be parallel.

Answers

Answer:

Yes, it is possible for vertical lines to be parallel.

Step-by-step explanation:

If you have two vertical lines- say one at x=4 and one at x=5, the x coordinate will always equal either 4 or 5. Since 4 and 5 are not the same number, the two lines will never touch, making them parallel.


Vertical lines are considered parallel because they run straight up and down, do not intersect, and maintain the same distance apart, despite having an undefined slope.

Yes, it is possible for vertical lines to be parallel. By definition, parallel lines are two or more lines that never intersect and are always the same distance apart. While the slope of a vertical line is undefined because it would require dividing by zero (as there is no change in the x-value), this does not prevent vertical lines from being parallel. In fact, all vertical lines are parallel to each other because they all run straight up and down, and so they will never meet, regardless of the fact that we cannot assign them a numerical slope value.

An example of this can be seen when considering two vertical lines in a coordinate plane, such as x = 1 and x = 5. Both lines are straight up and down, they do not intersect, and the distance between them is consistent along their entire length, fulfilling the criteria for being parallel lines.

Answers

Answer:

A)  $18

B)   [tex]y=2.50x+18[/tex]

C)   Coefficient of x-term represents the cost for each ride ticket and constant term represents the cost of admission to the fair.

Step-by-step explanation:

(A)

The county fair charges $2.50 per ticket for the rides and Henry bought 15 tickets for the rides.

So, the total cost of the 15 tickets will be:  [tex](\$2.50*15)=\$37.50[/tex]

He spent total $55.50 on ride tickets and fair admission.

So, the cost of admission to the fair will be:  [tex](\$55.50-\$37.50)=\$18[/tex]

(B)

If [tex]x[/tex] represents the number of ride tickets and [tex]y[/tex] represents the total cost, then the cost for [tex]x[/tex] number of ride tickets is [tex]\$2.50x[/tex]

So, the linear equation that can be used to determine the cost for anyone who pays for ride tickets and fair admission will be:   [tex]y=2.50x+18[/tex]

(C)

In the above linear equation, coefficient of x-term is 2.50, which represents the cost for each ride ticket.

And the constant term is 18, which represents the cost of admission to the fair.

If y= 14 when x = 8, find y when x = 12

Answers

HI!

It's simple. If y = 14 when x = 8, you would divide 14 by 8, giving you 1.75. THen, you would multiply this with  12 to get your x value, 21.

Hope this helps!

Hey mate


Here's your answer


y varies directly as x:

y ~ x or can be also written as y = kx where k is a constant scalar value

given: y = 14 when x = 8


y = kx or

k = y/x = 14/8 = 7/4

k = 7/4


find x when y = 21

y = k*x

x = y/k = 21/(7/4) = 21 *4 /7 = 12

A baker bought some flour. He used 2/5 of the flour to make bread and used the rest to make batches of muffins. If he used 16 lb. of flour making bread and 2/3 lb. for each batch of muffins, how many batches of muffins did he make?

Answers

To find the answer,we can first find the flour the baker left after making bread by setting an equation:

Let the orginal amount of flour be y

2/5y = 16
y = 16×5/2
y = 80/2
y = 40

There is 40lb of flour originally,after using 16 lb to make bread,he had:

40-16
=24lb

We can then find the muffin he made by dividing the answer above by 2/3:

24÷2/3
= 24 × 3/2
= 36

Therefore, he made 36 batches of muffins.

Hope it helps!

Let’s start out by what we already know. He used 2/5 of flour to make bread and he used 16 Ibs to make bread. This implies that the amount is (2/5)x=16.

2/5x=16

X= 5 x 16/2

X= 40

Since he used 16 Ibs of flour for bread, the rest are for the muffins, which is around 24 Ibs.


We know that each thing of muffins will use 2/3 Ibs of flour.

24/2/3

24/1/2/3

24/1 x 3/2 = 36
