**Step-by-step explanation:**

Let's solve for a.

3a+b=54

The Mulder Farm has 600 acres of land allotted for raising corn and wheat. The cost to cultivate corn is $40 per acre. The cost to cultivate wheat is $25 per acre. The Mulders have $18,000 available to cultivate these crops. How many acres each crop should the Mulders plant

### Answers

Answer: Corn = 200 acres

Wheat= 400 acres

Step-by-step explanation:

Let the number of acres of corn = c

Let the number of acres of wheat = w

The Mulder Farm has 600 acres of land allotted for raising corn and wheat. This will be:

c + w = 600

c = 600 - w

Cultivation cost equals:

= 40c + 25w = 18000

Since c = 600 - w, we slot it into the equation

40c + 25w = 18000

40(600 - w) + 25w = 18000

24000 - 40w + 25w = 18000

Collect like terms

24000 - 18000 = 40w - 25w

6000 = 15w

w = 6000/15

w= 400

400 acres of wheat will be planted

Since c + w = 600

c = 600 - 400

c = 200

200 acres of corn should be planted

Problem number 26 of the Rhind Papyrus says: Find a quantity such that when it is added to StartFraction 1 Over 4 EndFraction of itself the result is a 15. The modern day equation that models this problem is x plus StartFraction 1 over 4 EndFraction x equals 15.. What is the solution to the equation? x = 10 x = 12 x = 15 x = 30

### Answers

Answer:

The quantity is 12

Step-by-step explanation:

Here, we want to find the solution to the equation.

Let the quantity we are looking for be x;

According to the question;

The quantity plus a quarter of the quantity = 15

x + 1/4(x) = 15

x + x/4 = 15

Multiply through by 4

4x + (x/4)*4 = 15 * 4

4x + x = 60

5x = 60

x = 60/5

x = 12

Raleigh went to a gaming arcade for his birthday. His parents gave him $55 to spend. He purchased $14.25 in food and drinks, and put the rest of the money on a gaming card to spend at the arcade. Each game cost $1.25. Choose which inequality represents how many games "g" he can play.

### Answers

Answer:

Kindly check explanation

Step-by-step explanation:

Given that :

Total amount to spend = $55

Amount of food and drinks purchased = $14.25

Amount put on gaming card = $(55 - 14.25) = $40.75

Cost per game = $1.25

Number of games (g) he can play

Number of games g:

Amount put on gaming card / cost per game

= $40.75 / $1.25

= 32.6 games

g ≤ 32

2x - 5y = 5 and y = x + 2

### Answers

Answer:7

Step-by-step explanation:

**Answer:**

x = -5 & y = -3

**Step-by-step explanation:**

2x - 5y = 5 --------------------------(I)

y = x + 2 -----------------------(II)

**Using substitution method**

Substitute **y = x + 2** in equation (I)

2x - 5(x + 2) = 5

2x - 5*x + (-5)*2 = 5

2x - 5x - 10 = 5

**Combine like terms**

-3x - 10 = 5 **{Add 10 to both sides}**

** **-3x = 5 +10

-3x = 15 **{Divide both sides by (-3)}**

x = 15/(-3)

**x = -5**

Substitute the x = (-5) in equation (II)

y = -5 + 2

**y = -3**

If all of the dimensions in a cone increase by a factor of 5. How many times greater is the volume?

### Answers

**Answer:**

125 times bigger.

**Step-by-step explanation:**

A great way to visualize this problem is to think of it as a volume problem itself. Another good way to think about it is to plug in numbers in its place.

Way #1

5*5*5 (or 5^3)=125

Way #2

(2*2*2)=8

(2*5)*(2*5)*(2*5)=1000

1000/8=125

### Answers

**Answer:**

D. subtract 31 from both sides

you cant combine cuz theyre not like terms and you have to undo the constant number before you undo the second term in the equation so you will end up needing to do letter choice D first.

**Step-by-step explanation:**

hope this helped a little bit :)

**Answer: D. **subtract 31 from both sides

======================================================

Explanation:

The expression 31-12t is the same as 31+(-12t). Adding a negative is the same as subtracting a positive.

Then we can flip the two terms getting -12t+31. This is because we can add two numbers in any order.

So we're effectively solving -12t+31 = 211

**The first step is to subtract 31 from both sides** to undo the +31. We follow PEMDAS in reverse to isolate the variable.
