Using subsitution, which value of x makes this equation true? 4/5 - x = 1/5



A) x= 1/3

B) x= 2/5

C) x= 3/5

D) x= 5/2

Answer:

(18 , - 10)

Step-by-step explanation:

5x + 4y = 50 .... (1)

x + 2y = - 2 ... (2)

Solve (2) for "x"

x = - 2y - 2 .... (3)

(3) ----> (1)

5(- 2y - 2) + 4y = 50 ⇔ - 6y - 10 = 50 ⇒ y = - 10 .... (4)

(4) ----> (2)

x + 2(- 10) = - 2 ⇒ x = 18

(18, - 10)

The volume of the cone with a radius of 6 units, height of 8 units, and length of 10 units is approximately 301.5928 cubic units.

To find the volume of a cone, you can use the formula:

Volume = (1/3) * π * r^2 * h

Where π (pi) is approximately 3.14159, r is the radius of the cone, and h is the height of the cone.

In this case, the radius is given as 6 units, and the height is given as 8 units.

To calculate the volume, substitute these values into the formula:

Volume = (1/3) * 3.14159 * (6 units)^2 * 8 units

Volume = (1/3) * 3.14159 * 36 square units * 8 units

Volume ≈ 301.5928 cubic units

Therefore, the volume of the cone with a radius of 6 units, height of 8 units, and length of 10 units is approximately 301.5928 cubic units.

Answer:

4.47 liters

Step-by-step explanation:

To find how many liters were left, subtract the amount they drank from the original amount:

34.07 - 29.6

= 4.47

So, there were 4.47 liters of water left in the cooler.

After players drank 29.6 liters of water from 34.07 liters there is 4.47 liters of water left in the cooler.

Addition is also known as the sum, subtraction is also known as the difference, multiplication is also known as the product, and division is also known as the factor.

Given, A soccer coach filled a water cooler with 34.07 liters of water before a game.

The players drank 29.6 liters during their game.

∴ Liters of water that is left in the cooler is the difference between water-filled before the game to the water drank by players during their game which is,

= (34.07 - 29.6).

= 4.47 liters are left in the cooler.

Answer:

[tex]P(Consonant\ then\ Vowel) = \frac{14}{55}[/tex]

Step-by-step explanation:

Given

Word: PROBABILITY

[tex]n(Word) = 11[/tex]

Required

Determine P(Consonant then Vowel)

Frist we need to list out the consonants;

Consonants = PRBBLTY

[tex]n(Consonants) = 7[/tex]

Then Vowels

Vowels = OAII

[tex]n(Vowels) = 4[/tex]

[tex]P(Consonant\ then\ Vowel) = P(Consonants)\ and\ P(Vowels)[/tex]

[tex]P(Consonant\ then\ Vowel) = \frac{n(Consonants)}{n(Words)} \ and\ \frac{n(Vowels)}{n(Words) - 1}[/tex]

We used n(words) - 1 for the vowels because it's probability without replacement. So, when the consonant is picked, the length of letters reduced by 1

So, we have:

[tex]P(Consonant\ then\ Vowel) = \frac{7}{11} \ and\ \frac{4}{11 - 1}[/tex]

[tex]P(Consonant\ then\ Vowel) = \frac{7}{11} \ *\ \frac{4}{10}[/tex]

[tex]P(Consonant\ then\ Vowel) = \frac{7}{11} \ *\ \frac{2}{5}[/tex]

[tex]P(Consonant\ then\ Vowel) = \frac{14}{55}[/tex]

32 bags we sold last Saturday, and 64 today.

Step-by-step explanation:

So first, we make a ratio. 2:1, as she sold twice as much. yo could also write it in an equation; 2x+x=96. in both, we see that 3x is equal to 96, and so, x would be equal to 32. to find how many she sold today, multiply that number by 2, to get 64. Hope this helped :)

Answer:

I believe the answer is J. the corresponding angles are proportional, and the corresponding sides are congruent

Step-by-step explanation:

hope this helps :)

If the triangles below are similar the corresponding angles are proportional, and the corresponding sides are congruent. Option J is correct,

It is defined as the law to prove that two triangles have the same shape, but it is not compulsory to have the same size. The ratio of the corresponding sides is in the same proportions and the corresponding angles are congruent.

Congruent triangles are those that are exactly the same size and shape. Congruent is represented by the symbol ≅ When the three sides and three angles of one triangle match the dimensions of the three sides and three angles of another triangle, they are said to be congruent.

Thus, if the triangles below are similar the corresponding angles are proportional, and the corresponding sides are congruent. Option J is correct.

Answer:

5.5%

Step-by-step explanation:

The formula for Simple Interest = PRT

Where

Simple Interest = $115.50

P = Principal = $700

R = Interest rate = ??

T = Time in years = 3 years

$115.50 = $700 × R × 3

R = $115.50/$700 × 3

R = $115.50/$2100

R = 0.055

R = Interest rate = 0.055

We Multiply by 100

= 0.055 × 100

= 5.5%

Start with the initial fee which is $4. Then times 2 with your miles for an example: (money with miles)2 x 6(miles) and you should have $12 dollars in total  2 x 4 which equal $8 and 2x2 which equal 4...

2 x 6 = 12

2 x 4 = 8

2 x 2= 4

add all those up and you should get 28..
