that cost $5.20/lb with walnuts
that cost $6.40/lb. How many
pounds of each were used to
make a 45 pound mixture that
cost $6/lb?

Answer:

5

Step-by-step explanation:

[tex]12 - 2(3h) = - 18 \\ 12 - 6h = - 18 \\ - 6h = - 18 - 12 \\ - 6h = - 30 \\ h = \frac{ - 30}{ - 6} \\ h = 5[/tex]

Answer:

H=5

Step-by-step explanation:

Simplifying the equation

We multiply 2(3H) =6H, so the equation is now 12-6H=-18

Isolating the Variables

Then, we subtract 12 from both sides, giving us -6H = -30

Finding H

Finally, we divide both sides by -6, so H= 5

Hii :)

Lets solve for x (x being what time jake will leave)

First, what do we know?

  We know..

2:30-53=1:37

So jake should leave around 1:00pm-1:30pm

2:30-1:30=1:00

Hope this helps

Answer:

4/16

Step-by-step explanation:

pls give me brainliest

Answer:

Hi!

So, for question 4, when you divide it by two, you can split it horizontally to make it 6 squares instead of 3 rectangles from the model of the 1/3, leaving 2 shaded squares and 4 unshaded squares. And since you're dividing it by 2, you only use 1 of the shaded squares.

For question 5, I made the one-half horizontal instead of vertical so you can easily overlap the 2 models when you multiply them. Similar to question 4, the model becomes 6 squares and the 2 models overlap on one square.

Hope this helps! :)

Answer:

Each additional copy increased the time by 8 seconds

Step-by-step explanation:

It is increased because- the amount of seconds is increasing every time an additional copy is added to the table

it is 8 because- 12 increases by 8 to get 20, and 20 increases by 8 to get 28, and 28 increases by 8 to get 36.

Answer:

44

Step-by-step explanation:

36+9=45

45-1=44

Answer=44

Hey there!

Let's solve this equation for N.

First, let's work out 36+9:

45

45-N=1

subtract 45 from both sides:

-N=1-45

-N=-44

Divide both sides by -1:

N=44 (Option B)

Hope everything is clear.

Let me know if you have any questions!

Always remember: Knowledge is power!

Answer:

Step-by-step explanation:

To find the value of x, isolate it on one side of the equation.

3/4x+9=3

First, subtract by 9 from both sides.

3/4x+9-9=3-9

Solve.

3-9=-6

Rewrite the problem down.

3/4x=-6

Multiply by 4 from both sides.

4*3/4x=4(-6)

Solve.

3x=-24

Then, you divide by 3 from both sides.

3x/3=-24/3

Solve.

Divide these numbers goes from left to right.

-24/3=-8

x=-8

Variables and negative signs should appear in the answer.

I hope this helps you! Let me know if my answer is wrong or not.

Answer:

x = -8

Step-by-step explanation:

Subtract 9 both sides:

⇒ 3/4x + 9 = 3

⇒ 3/4x + 9 - 9 = 3 - 9

Simplify the L.H.S and the R.H.S:

⇒ 3/4x = -6

Use cross multiplication:

⇒ 3x/4 = -6

⇒ 3x = -6 × 4

Simplify the R.H.S:

⇒ 3x = -6 × 4

⇒ 3x = -24

Divide 3 both sides:

⇒ 3x/3 = -24/3

⇒ x = -8

Answer: 3/52 (~5.77%)

What we know:

How to solve:

  We need to find the probability of drawing one of 3 diamond face cards, which gives us all of the information we need. Using division, we can create a 'x amount of diamond face cards/y amount of total cards' probability.

Probability of a diamond  face card

Where P is the probability of drawing that card, x is the number of diamond face cards, and y is the total amount of cards.

Set up equation                                                     P = x/y

Substitute                                                               P = (3)/(52)

Answer: 3/52 (~5.77%)

Because there are 3 diamond face cards in the deck, the chance of drawing one is {3 cards out of 52 total}, which is 3/52.

The chance of drawing ANY face card is {(3 per suit, 4 suits=) 12 cards out of 52 total} 12/52 (~23.08%),

The chance of drawing ANY diamond card is {1 suit out of 4 suits} 1/4 (25%)

Answer: The volume is 30

Step-by-step explanation: This is the answer because you multiply the numbers and you get 30FT.

Answer:

30

Step-by-step explanation:

Given:

QR= 45 mm

RS= 15, (1/3 of QR is 15).

QT is 90 mm

We must find ST.

Equation:

Use Segment Addition Postulate Theroem,

QR+RS+ST=QT

Subsitue the values we know

45+15+ST=90

60+ST=90

ST=30So ST length is 30 m

Answer:

im sorry if im wrong  

Answer:

B. 150 ft

Step-by-step explanation:

Perimeter of a rectangle = 2(Length) + 2(Width)

Here, we are given the perimeter and width and we want to find the length

We can do so by plugging in what we are given into the perimeter formula and solving for length.

Perimeter = 2(Length) + 2(Width)

Perimeter = 450 and Width = 75

450 = 2(Length) + 2(75)

We now solve for length

==> simplify multiplication 2(75) = 150

450 = 2(Length) + 150

==> subtract 150 from both sides

300 = 2(Length)

==> divide both sides by 2

150 = Length

And we are done!

The answer is B 150ft

Answer:

1134 cubic inches of soil

Step-by-step explanation:

You can split the shape apart and then add the volumes together at the end.

The bottom shape is 21x7x2

=294

The top shape is 12x10, and the last side can be foundfrom the other shape’s depth, 7.

12x10x7

=840

294+840=1134

Answer:

Step-by-step explanation:

I'm not sure what you mean by those steps mean but here is how I would answer using the elimination method:

3x - 12y = 5

minus (each term separately: 3x - 3x, -12y - -y, and 5 - 9)

3x - y = 9

This eliminates the 3x and = -11y = -4

You can then simplify from there and get y = 4/11
