Ana saw 7 kitten and 9 chicks at the pet store.

Step-by-step explanation:

Given,

Number of heads = 16

Number of legs = 46

A chick has 2 legs and a kitten has 4.

Let,

x represent the number of kitten and y represent the number of chicks.

According to given statement;

x+y=16     Eqn 1

4x+2y=46   Eqn 2

Multiplying Eqn 1 by 4

4(x+y=16)\\4x+4y=64\ \ \ Eqn\ 3

Subtracting Eqn 2 from Eqn 3

(4x+4y)-(4x+2y)=64-46\\4x+4y-4x-2y=18\\2y=18

Dividing both sides by 2

\frac{2y}{2}=\frac{18}{2}\\y=9

Putting y=9 in Eqn 1

x+9=16\\x=16-9\\x=7

Ana saw 7 kitten and 9 chicks at the pet store.

Polygon ABCD is defined by the points A(-4,2) B(-2, 4), C(1, 3) & D(2,2). Match the coordinates of the points of the transfo
dalvyx [7]

Answer:

D'(-2, 2); C''(3, -1); A'''(4, -2); and B''(4, 2)

Step-by-step explanation:

See attachment for the figure.

<u>For D'</u>, rotating the point (2, 2) 90° counterclockwise. This maps each point (x, y)→(-y, x); it takes (2, 2)→(-2, 2).  

For C'', rotating the point (1, 3) 90° clockwise.  This maps each point (x, y)→(y, -x); it takes (1, 3)→(3, -1).

For A''', rotating the point (-4, 2) 180° clockwise.  This maps every point (x, y)→(-x, -y); it takes (-4, 2)→(4, -2).

For B'', rotating the point (-2, 4) 270° counterclockwise.  This is the similar as rotating the point 90° clockwise.  This maps every point (x, y)→(y, -x); it takes (-2, 4)→(4, 2).

A certain pickup truck gets 20mpg in the city and 28 mpg on the highway. If the driver drives 270 mi on 11 gal of gas, determine
Snezhnost [94]

Answer:

95 city and 175 highway miles.

Step-by-step explanation:

The driver gets 20 mpg in city, and 28 mpg on the highway.

An equation that could be written is

20x+28y=270

This equation accounts for the distance traveled.

x+y=11

This equotion accounts for how many gallons were driven.

Multiply the bottom equation by 20, so you can solve the set of equations.

20x+28y=270

20x+20y=220

subtract them

8y=50

y=6.25

now plug this back into x+y=11

x+6.25=11

x=4.75

Now 4.75×20=95 city miles and 6.25×28=175 highway miles.
