Alex bought four 15-pound bags of dog food, three 4 1/2 pound bags of cat food, and two 1/2-pound bags of fish food. How many pounds of pet food did Alex buy?

Answer:

35% of 60 = 21

the answer is 21

this is how you set it up

x/60=35/100

you first multiply 35 and 60 and your answer should be 2100 then you divide 2100 by 100 and that equals 21

i hope this helped i learned about this a month ago

Answer:

Step-by-step explanation:

3x is a varable and -1 is an integer

Answer:

The solution to the system of equations is:

[tex]x = -9[/tex],   [tex]y=-3.4[/tex]

Step-by-step explanation:

Given the system of equations

-2.1x + 4y = 5.3

2.1x - 5.5y = -0.2

Solving the system of equations using the linear combination method

[tex]\begin{bmatrix}-2.1x+4y=5.3\\ 2.1x-5.5y=-0.2\end{bmatrix}[/tex]

adding the equations

[tex]2.1x-5.5y=-0.2[/tex]

[tex]+[/tex]

[tex]\underline{-2.1x+4y=5.3}[/tex]

[tex]-1.5y=5.1[/tex]

solving -1.5y = 5.1 for y

[tex]-1.5y=5.1[/tex]

Divide both sides by -1.5

[tex]\frac{-1.5y}{-1.5}=\frac{5.1}{-1.5}[/tex]

[tex]y=-3.4[/tex]

substitute y = -3.4 in 2.1x - 5.5y = -0.2

2.1x - 5.5y = -0.2

2.1x - 5.5(-3.4) = -0.2

2.1x + 18.7 = -0.2

2.1x = -0.2-18.7

2.1x = -18.9

Divide both sides by 2.1

[tex]\:\frac{2.1x}{2.1x}\:\:=\:\:\frac{-18.9}{2.1}[/tex]

[tex]x = -9[/tex]

Therefore, the solution to the system of equations is:

[tex]x = -9[/tex],   [tex]y=-3.4[/tex]

Answer:

We can write 7 + 2 + 1 in two different ways.

a)

b)

Step-by-step explanation:

The commutative property of addition states that we can add the numbers in any order and get the same answer.

For example, if we add 'a' and 'b' together, the commutative property of addition states that we would get the same answer whether we add a + b or b+a.

In other words,

a + b = b + 1

In our case, we are given

7 + 2 + 1

According to the commutative property of addition, we can add the number in any order and get the same answer.

Therefore, we can write 7 + 2 + 1 in two different ways.

a)

b)

Verification:

Thus, the answer will remain the same in any order.

i.e.

7 + 2 + 1 = 7 + 1 + 2 = 1 + 7 + 2

Answer:

2 1/4 hours

Step-by-step explanation:

Okay, so- The first thing I did was see how much they got done per hour. Like this:

Sally  ⇒

3 hours = 1 room

1 hour = 1/3 of the room

Steve ⇒

9 hours = 1 room

1 hour = 1/9 of the room

Sally + Steve ⇒  

1 hour = 1/3 + 1/9 = 3/9 + 1/9 = 4/9

So, they get 4/9 of a room done in 1 hour.

Number of hours needed ⇒

1 ÷ 4/9 = 2 1/4  

Answer: They need 2 1/4 hours to paint the room.

Answer:

a = 16

Step-by-step explanation:

The altitude YB is at right angles to the base XZ , then

∠ YBZ = 90° , so

6a - 6 = 90 ( add 6 to both sides )

6a = 96 ( divide both sides by 6 )

a = 16

Answer:

intercept

16,0

0,6

Step-by-step explanation:

Answer:

Substitute 0 for the x-value in the equation and solve for y. The result is y = 6, so the y-intercept is at (0, 6). Next, substitute 0 for the y-value in the equation and solve for x. The result is x = 16, so the x-intercept is at (16, 0).

Step-by-step explanation:

I did the assignment on edge its 8 grade math

Answer:

x = 2, y= -1 Or (2, -1)

Step-by-step explanation:

Let’s solve the system using substitution. First we can set the equations equal to each other:

x-3= -2x +3

Now solve for x

3x-3= 3

3x = 6

x=2

Now that we have x, we can plug it back into one of the original equations to get y

y= x-3

y= 2-3

y = -1

Finally, the solution to the system of equations is (2, -1).

Answer:

(2,-1)

Step-by-step explanation:

1.) y = x - 3

    y = -2x + 3

2.) Multiply top equation by 2

    2y = 2x - 6

    y = -2x + 3

3.) Add equations

    3y = -3

4.) Divide 3 from each side

     y = -1

5.) Substitute -1 for y in second equation

    -1 = -2x + 3

6.) Solve

     -4 = -2x

     x = 2

Therefore, (2, -1)

Answer:

350 miles

Step-by-step explanation:

if max drives 105 miles per week

you should first find out how many miles max drives per day.

there are 7 days in a week so :

105 ÷ 7 = 15

so for 30 days max will drive 15 × 30 = 350 miles

1 day : 15 miles

30 days : 350 miles

Answer:

450!!!!!!!!!!

Answer:

[tex]a_{n}[/tex] = 6n - 3

Step-by-step explanation:

There is a common difference d between consecutive terms, that is

d = 9 - 3 = 15 - 9 = 21 - 15 = 6

This indicates the sequence is arithmetic with n th term

[tex]a_{n}[/tex] = a₁ + (n - 1)d

where a₁ is the first term and d the common difference

Here a₁ = 3 and d = 6, then

[tex]a_{n}[/tex] = 3 + 6(n - 1) = 3 + 6n - 6 = 6n - 3
