PLEASE ANSWER ASAP CORRECTLY FOR BRAINLEST!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

Answer:

The smaller number is 8

The bigger number is 11

Step-by-step explanation:

let the first number be A

let the second number be B

A + 2B = 30..... equation 1

A + B = 19...... equation 2

Subtract equation 2 from 1.

A + 2B = 30

- A + B = 19

-------------------

0 + B = 11

B = 11

Substitute B = 11 into equation 2

A + B = 19

A + 11 = 19

collect like terms

A = 19-11

A = 8.

A= 8 and B = 11

Answer:

D. 2bh+bh

Step-by-step explanation:

You can divide that shape into five separate pieces, 4 triangles and 1 square.

The formula for the area of a triangle is A=1/2bh.

Multiply this by 4 becuase there are 4 triangles and you get A=2bh.

Then you add on the area of the square and you have A=2bh+bh

Answer:

166

Step-by-step explanation:

let two numbers be x and y

according to question,

x+y=527..........equation 1

x-y=195...........equation 2

add both the equations you will get

x=361 and y= 166

So the smaller of two numbers is y=166

Answer:

They are mutually exclusive.

Step-by-step explanation:

A and B are mutually exclusive events if they cannot occur at the same time. This means that A and B do not share any outcomes and P(A AND B). Therefore, A and C are mutually exclusive

Answer:

11 pounds

Step-by-step explanation:

Just divide the cats weight by 2 and then add 2

(18)/2 + 2

Step-by-step explanation:

First car.

0.2 gallons used for 7 miles.

Distance drive on 1 gallon of gas [tex]=\dfrac{7}{0.2}=35\ \text{miles}[/tex]

Second car.

0.5 gallons used for 12 miles.

Distance drive on 1 gallon of gas [tex]=\dfrac{12}{0.5}=24\ \text{miles}[/tex]

Third car.

0.9 gallons used for 25 miles.

Distance drive on 1 gallon of gas [tex]=\dfrac{25}{0.9}=27.8\ \text{miles}[/tex]

So, the first car traveled fast while the second car traveled least. Hence, the sequence is first car > third car > second car.

Answer:

x=24/7

Step-by-step explanation:

3(x+2)+4(x-5)=10

3x+6+4(x-5)=10

3x+6+4x-20=10

7x+6-20=10

7x-14=20

7x=24

x=24/7

Answer:

7 units

Step-by-step explanation:

Answer:

The standard deviation of this probability distribution is 1.2.

Step-by-step explanation:

We have that:

P(X = 0) = 0.25

P(X = 1) = 0.3

P(X = 2) = 0.1

P(X = 3) = 0.35

Mean:

Each value multiplied by its probability. So

[tex]M = 0*0.25 + 1*0.3 + 2*0.1 + 3*0.35 = 1.55[/tex]

Variance:

Sum of the squares of the values subtracted from the mean, and multiplied by its probability.

[tex]V = 0.25*(0-1.55)^2 + 0.3*(1-1.55)^2 + 0.1*(2-1.55)^2 + 0.35*(3-1.55)^2 = 1.4475[/tex]

Standard deviation:

Square root of the variance. So

[tex]S = \sqrt{V} = \sqrt{1.4475} = 1.2[/tex]

The standard deviation of this probability distribution is 1.2.

Answer:

11/8 or 1 & 3/8

Step-by-step explanation:

5 & 2/8=21/4

3&7/8=31/8

21/4-31/8=11/8 or 1 & 3/8

Answer:

[tex]1\frac{3}{8}[/tex]

Step-by-step explanation:

Convert to improper fractions.

[tex]\frac{42}{8} -\frac{31}{8}[/tex]

Subtract.

[tex]\frac{11}{8} = 1\frac{3}{8}[/tex]

good luck, i hope this helps :)

Answer:

7x - 18

Step-by-step explanation:

x multiplied by seven = 7x

eighteen subtracted from product (7x) = -18

7x - 18

Answer:

7x-18

Step-by-step explanation:

the ans is 7x-18 because x is multiplied to 7 so its 7x

Step-by-step explanation:

distance = -6-(-2) and 4-2

-6+2 and 2

-4 and 2 is distance

Answer:

[tex]d = \sqrt{(x_{2}-x_{1})^{2} +(y_{2}-y_{1})^{2} }[/tex]

d = √(4 - (-2))² + (2 - (-6))²

d = √36 + 64

d = 10

Answer:

y = 3x + 5 option A

Step-by-step explanation:

For 2 lines that are parallel with slopes m1 and m2, the slopes are equal. Hence

m1 = m2

Given the line y = 3x - 5 Comparing with the general equation of a line

y = mx + c where m is the slope of the line

m = 3

hence m1 = m2 = m = 3

For the line that passes through the given point (2,11) Using

y - y1 = m (x - x1)

y - 11 = 3(x - 2)

y - 11 = 3x - 6

Add 11 to both sides

y = 3x - 6 + 11

y = 3x + 5
