Answer:

he sold 22 dogs and 13 cats

number of dogs = 22

plz mark my answer as brainlist plzzzz and option C .22 is the correct answer

Answer:

c. 22

Step-by-step explanation:    

75 x 22= 1650

35-22=13

13 x 25= 325

325+1650= 1975

Answer:

x = 3.8 + 53.6

Step-by-step explanation:

From the info that they gave you, you can tell that the original number is unknown, so that is x. Since Sushil is subracting 3.8, meaning, to get x, you're going to have to do the opposite which is........addition! So, to get x, you have to add 3.8, and 53.6. I hope I make sense!!

Answer:

2. A(n) = 8+(n-1)-6

3. (-3-(-4))/(-6-8)

= -1/14

Answer:

see explanation

Step-by-step explanation:

(2)

The explicit formula for an arithmetic sequence is

[tex]a_{n}[/tex] = a₁ + (n - 1)d

where a₁ is the first term and d the common difference

Here a₁ = 8 and d = a₂ - a₁ = 2 - 8 = - 6 , thus

[tex]a_{n}[/tex] = 8 - 6(n - 1) = 8 - 6n + 6 = 14 - 6n

(3)

Calculate the slope m using the slope formula

m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]

with (x₁, y₁ ) = (8, - 4) and (x₂, y₂ ) = (- 6, - 3)

m = [tex]\frac{-3+4}{-6-8}[/tex] = [tex]\frac{1}{-14}[/tex] = - [tex]\frac{1}{14}[/tex]

Answer:

x = 2 , y = 0 , z = 3

Step-by-step explanation:

Cramer's rule is a rule through which we can find the solution of linear equation.

we have the three linear equations as

x+2y+3z=11

2x+y+2z=10

3x+2y+z=9

AX=B  

A: coefficient matrix

X= unknown vectors(x,y,z)

D = values of the linear equation (11 , 10 , 9)

now we find the determinant of the given linear equation

determinant of the matrix will be

A = [tex]\left[\begin{array}{ccc}1&2&3\\2&1&2\\3&2&1\end{array}\right][/tex]  = 1(1-4) - 2(2-6) + 3(4 - 3)

                    = 1(-3) - 2(-4) + 3(1)

                    = -3+8+3 = 8

also D[tex]\neq 0[/tex]

so the determinant is Non zero we can apply Cramer's rule

we will be replacing the first column of the coefficient matrix A with the values of D

by replacing the first column we will get the value of the variable 'x'

Dx =  [tex]\left[\begin{array}{ccc}11&2&3\\10&1&2\\9&2&1\end{array}\right][/tex]   = 11(1-4) -2(10-18) + 3(20-9) = -33+16+33 = 16

x = [tex]\frac{Dx}{D}[/tex]  = [tex]\frac{16}{8}[/tex] = 2

similarly

Dy = [tex]\left[\begin{array}{ccc}1&11&3\\2&10&2\\3&9&1\end{array}\right][/tex] = 1(10-18) -11(2-6) + 3(18 -30) = -8 +44 -36 = 0

y = [tex]\frac{Dy}{D}[/tex] = 0

Dz= [tex]\left[\begin{array}{ccc}1&2&11\\2&1&10\\3&2&9\end{array}\right][/tex] = 1(9 - 20) -2(18 - 30) + 11(4 -3) = -11 +24 +11 = 24

z = [tex]\frac{Dz}{D}[/tex] = [tex]\frac{24}{8} = 3[/tex]

so we have the solution as

x = 2 , y = 0 , z = 3

Therefore the solution for the given linear equations is (2,0,3).

Answer:

x = 0

Step-by-step explanation:

add 23 on both side and x equals zero

substitute x for 0, and the equation is still correct

Answer:

Both are related as both have the answer same that is x=2.

Step-by-step explanation:

Answer:

hosta = 2 $,,, geranium = 5 $

Step-by-step explanation:

if we make two eq.

1) .... 54 = 2h + 10g

2) ...... 40 = 10h + 5g

if we multiply 1st by -5 it turns to

3) ..... -270 = -10h - 50g

cancel both 10h

add eq. .. becomes : -230 = -46g

g = 5

substitute in any find , that h = 2

Answer:

The measure of angle F is 67.6°

Step-by-step explanation:

In the right triangle DEF

∵ ∠E is the right angle

∵ Side DF is opposite to ∠E

∴ DF is the hypotenuse of the triangle DEF

∵ Side EF is the adjacent side of ∠F

∵ The cosine ratio = [tex]\frac{Adjacent}{Hypotenuse}[/tex]

∴ cos∠F = [tex]\frac{EF}{DF}[/tex]

∵ EF = 8 units

∵ DF = 21 units

→ Substitute them in the cosine ratio above

∴ cos∠F = [tex]\frac{8}{21}[/tex]

→ Use [tex]cos^{-1}[/tex] to find the measure of angle F

∵ m∠F = [tex]cos^{-1}(\frac{8}{21})[/tex]

∴ m∠F = 67.60731219 degrees

→ Round it the nearest tenth of a degree

∴ m∠F = 67.6°

∴ The measure of angle F is 67.6°

Answer:

Carla needs to make at least 11 two-pointer shots in the surrent game

Step-by-step explanation:

The first thing we can do is to find the difference between the number of points that Carla scored in her first game and her second game.

This will be 46 - 24 = 22 points difference

Carla needs to make a certain number of two-pointers to get at least the same score she had in her previous game.

We can get this number of two-pointers that needed to be made by dividing the difference in scores by 2

i.e number of two-pointer shots = 22/2 =11 shots

Therefore, Carla needs to make at least 11 two-pointer shots to be able to get the same score in her current game.
