Find the value of x when y=13. Y=-3x+4

Answers

Answer: x= -3

Explanation:
If y is equivalent to 13 then our equation would be

13=-3(x)+4

To receive what x is then you’d have to switch it around and find it as

3x+13=4

And 3x=-9

If you divide both sides by 3 then

x=-3

That’s the best I can do to explain it

Answers

Answer:

C. [tex]30\sqrt{2}[/tex]  

I hope this helps!

The simplified form of expression 3 times the square root of 200 is 30√2 ( thirty times square root 2 ) .

To simplify the expression 3 times the square root of 200, we can break it down into smaller components .

First, let's simplify the square root of 200 :

√ 200 = √ ( 100 × 2 ) = √ 100 × √ 2 = 10√2

Now, we substitute this simplified value back into the original expression :

3 × √ 200 = 3 × ( 10√ 2 ) = 30√ 2

Therefore, the simplified form of 3 times the square root of 200 is 30√2 .

Daughter’s current age is 6 years which is 1/5 th of her mother’s age. After how many years mother’s age will be three times greater than daughter’s age.

Answers

Answer:

6 years

Step-by-step explanation:

6 = ⅕m

m = 30

"mother's age will be three times greater than daughter's age"—Not sure what "three times greater than" means. I will interpret it as: "mother's age will be three times daughter's age."

In x years, mother will be 30+x and the daughter will be 6+x.

30+x = 3(6+x) = 18+3x

12 = 2x

x = 6

In 6 years, the mother will be 36 and the daughter will be 12.

There are 60 dogs at the doggie daycare, 1/3 of the dogs are large dogs, 1/6 of the dogs are medium dogs, and the rest are small dogs. How many small dogs are there? (HOW DID YOU GET YOUR ANSWER PLEASE SHOW YOUR WORK!!)
A. 1/17
B. 136
C. 30
D. 2/19
E. 25

Answers

Answer:

C. 30

Step-by-step explanation:

First, you want to make the two fractions have the same denominator. This means, that instead of saying that 1/3 of the dogs being large, you would say that 2/6 of the dogs are large. Then, combine the amount of large and medium dogs, making large and medium dogs 3/6 of all the dogs. The amount of small dogs must complete this fraction, so now we know that 3/6 of the dogs are small. This means half of the dogs are small dogs. Divide 60 by 2, and you have your answer.

The answer would be 30 small dogs

1/3×60 =20 = 20 large dogs

1/6×60=10= 10 medium dogs

20+10=30

60-30=30 = 30 small dogs

Answer:

First One is C and the second one is A

Step-by-step explanation:

I got it wrong then found out the answers

Systems of equations are collection of multiple equations

We can get system B from system A by: subtracting both equations in system A and by bringing the first equation of system A

The systems of equations are given as:

System A

5x + y = 3

4x - 7y = 8

System B

5x + y = 3

x + 8y= -5

Subtract 4x - 7y = 8 from 5x + y = 3

So, we have:

[tex]\mathbf{5x - 4x + y+7y = 3 - 8}[/tex]

[tex]\mathbf{x + 8y =- 5}[/tex]

This means that, we can get system B from system A by:

Four cards will be dealt off the top of a well-shuffled deck. There are two options. (i) To win $10 if the first card is club and the second is a diamond and the third is a heart and the fourth is a spade. (ii) To win $10 if the four cards are of four different suits. Compute the probability of winning $10 for each case. Which option is better

Answers

Answer:

0.0043957 ; 0.105498 ; 2nd option is better

Step-by-step explanation:

Option 1:

First card :P(club) = 13/52

Second card: P(diamond) = 13/51

Third card : P(heart) = 13 / 50

Fourth card: P(spade) = 13/49

Hence,

P(club, diamond, heart, spade) = (13/52) * (13/51) * (13/50) * (13/49) = 0.0043957

Probability of winning $10 = 0.0043957

2nd option:

P(card of different suit) [order of arrangement does not matter]

(13C1 * 13C1 * 13C1 * 13C1) / 52C4

= 28561 / 270725

= 0.105498

Probability of winning $10 = 0.105498

Because the probability of winning for the second option is higher than for the first option, then the second option is better.

why is 4320 divisible by 3, 9, and 10

Answers

Answer:

One integer A is divisible by another integer B,

if after dividing them, A ÷ B, the remainder is zero.

4,320 is divisible by 10, if there is an integer 'n' such that 4,320 = 'n' × 10.

Notice that dividing our numbers leaves no remainder:

4,320 ÷ 10 = 432 + 0;

So, 4,320 = 432 × 10;

=> 4,320 is divisible by 10.

10 is called a divisor (a factor) of 4,320.

10 | 4,320

The shorthand notation A | B means A divides B.

4,320 is a multiple of 10.

Note that this is also the first step of the Euclidean Algorithm, where the division of the numbers stops when a remainder equal to zero is reported.

4,320 is divisible by 10:

For the first figure, draw a vertical line from the upper right corner to the base. Then you can see that the figure is a combination of two shapes: A rectangle that is 8 high and 6 wide, and a right triangle that has altitude of 8 and base of 4.

Area of rectangle = 8*6 = 48
Area of triangle = (1/2)*8*4 = 16
Total area = 48+16 = 64 square units
:::::
The second figure is a parallelogram with equal sides. Note that if you cut off the triangular area and attach it to the top of the figure, you get a rectangle, so the area is 15 times 16 = 24 units.
