Drag A Statement Or Reason To Each Box To Complete This Proof.If 5(x+8)=25, Then X=3. (2024)

Mathematics High School

Answers

Answer 1

Answer:

Step-by-step explanation:

Prove that,

−5(x+8) = −25 then x = -3

−5(x+8) = −25

By distributive property,

-5x - 40 = -25

Adding 40 to both sides, that is, Additive property of equality

-5x - 40 + 40 = -25 + 40

-5x = 15

Divide both sides by -5, that is Division property of equality

-5x / -5 = 15 / -5

x = -3

Hence, x = -3 has been proved

Answer 2

Answer:

Statement Reason

1. -5(x+8)=-25 Given

2. −5(x+8) −5=−25/−5 Division Property of Equality

3. X+8=5 Simplifying

4. x+8−8=5−8 Subtraction Property of Equality

5. x=−3 Simplifying

Answers

Answer:

[tex]f(x)=128-14x[/tex]

Step-by-step explanation:

So, we started out with 128 ounces of milk.

Each day, Joann drinks 14 ounces of milk.

Therefore, the amount of milk left over after x days is 14 times x subtracted from 128.

Therefore, our function is:

3 Caleb claims that when you multiply a number by 10, you can just write a 0 at the right end of the number. Caleb gives the example 6 x 10 to prove his claim always true. Noah does not agree with Caleb. He gives the example 0.6 x 10 to prove that Caleb's claim is not always true Who is correct? Explain your answer.​

Answers

Answer:

They are both correct

Step-by-step explanation:

It's interpretation of the concept. In common practice multiplying by 10 means you add a zero and that's what we teach 10 year olds. But what does adding a zero mean? It means adding a place value and that's what you learn when you are

So in both examples just add a decimal:

2.0 x 10 = 20.

0.2 x 10 = 2.0

In conclusion, it depends on the level of precision required in the discussion and the level of maturity as to who is correct in their examples. If you are teaching 3rd graders math, by all means you add a zero. If you are discussing physics you are shifting over a place value.

An ice chest contains 3 types of drinks: 10 apple juries 15 grape juices and 15 bottles of water what is the probability of getting a drink that does not contain fruit juice

Answers

Answer: [tex]\dfrac{3}{8}[/tex]

Step-by-step explanation:

Given: An ice chest contains 3 types of drinks: 10 apple juries 15 grape juices and 15 bottles of water.

Total drinks= 10+15+15 = 40 (Total outcomes)

Number of drink that does not contain fruit juice = Number of bottles of water = 15 (Favorable outcomes)

The probability of getting a drink that does not contain fruit juice = [tex]\dfrac{Favorable\ outxcomes}{Total\ outcomes}[/tex]

[tex]=\dfrac{15}{40}\\\\=\dfrac{3}{8}[/tex]

So, the required probability = [tex]\dfrac{3}{8}[/tex] .

The length of the 2 black rods is equal to that of the 3 grey rods. The length of the white rod is equal to the total length of the 2 black and 3 grey rods as shown in the figure.
Therefore the length of the grey rod is ______ the length of the white rod.
Which of these can come in the blank above?
a)/
b) /
c) /
d) /3

Help❤️^^

Answers

Answer:

Length of grey rod is [tex]\frac{1}{4}[/tex]th of the white rod.

Step-by-step explanation:

Let the length of each black rod = b units

Length of 2 black rods = 2b

Length of each grey rod will be = g units

Length of 3 grey rods = 3g

Since, length of 2 black rods = length of 3 grey rods

2b = 3g ----- (1)

Length white rod = Length of 2 black rods + Length of 3 grey rods

w = 2b + 3g

From the equation (1),

w = 2b + 2b

= 4b

b = [tex]\frac{w}{4}[/tex]

Therefore, length of grey rod is [tex]\frac{1}{4}[/tex]th of the white rod .

A ceiling fan has 18 inch blades and turns at a rate of 45 revolutions per minute. What is the angular
speed in radians per hour?

2700n rad/1 hr
97200n rad/1 hr
5400n rad/1 hr
90n rad/1 hr

Answers

Answer:

5400π rad/1 hr

Step-by-step explanation:

The angular speed is used to measure the speed of an object in rotational motion. The angular speed is the ratio of the distance traveled by the object in radian to the time taken in seconds, hence its unit is in rad/s.

Given that the angular speed = 45 revolutions per minute

1 rev = 2π rad

1 min = 1/60 hr

Hence:

Angular speed = [tex]\frac{45\ rev*\frac{2\pi \ rad}{1 \ rev} }{1\ min*\frac{1\ hr}{60\ min} }=\frac{90\pi\ rad*60}{1\ hr} = \frac{5400\pi \ rad}{1\ hr}[/tex]

The angular speed in rad/hr = 5400π rad/1 hr
