Helen ate 1/10 of a cake. She divided The remainder into 3 equal portions. What fraction of the cake was in each portion

### Answers

**Answer:**

As she ate 1/10 of cake, we need to know how many cake remains after it, so we can substract:

1 - 1/10 = 10/10 - 1/10 = 9/10

Then, we need to divide the 9/10 into 3 portions:

(9/10) / 3 = 9/30 = 3/10

So we know the fractions would be 3/10 each on this situation..

**Explanation:-**

Given that the explicit rule

[tex]a_{n} = -3n +2[/tex]

Put n=1

⇒ a₁ = -3(1) +2

a₁ = -1

Put n=2

⇒ a₂ = -3(2)+2

a₂ = -6+2

a₂ = -4

Put n=3

a₃ = -3(3)+2

a₃ = -9+2

a₃ = -7

Answer: The answer should be 72

Explanation: Triangles add up to 180. The two bottom points are the same. So you would take 180 and subtract it by 36. That would give you 144. You would then take 144 and divide it by 2, because the two angles are the same and your only trying to find one.

4) 4x + 3y = 56

2x + y = 24

Solve using elimination please show work

### Answers

**Answer:**

x = 8 y = 8

**Step-by-step explanation:**

Multiply 2nd equation by -3 to get -6x - 3y = -72

Now 4x + 3y = 56

-6x - 3y = -72

-2x = -16

x = 8

Substitute x = 8 into the 2nd equation

2(8) + y = 24

16 + y = 24

y = 8

Check: Substitute the values into the 1st equation

4(8) + 3(8) = 32 + 24 = 56 So we have the correct values for x and y

On the planet Gespli, there are 10 pisquets to every 7 vreels. if farmer Frank has 40 vreels on his rew farm, how many pisquets are on the farm

### Answers

**Answer:**

57 pisquets

**Step-by-step explanation:**

Ratio of pisquets:vreels = 10:7

Ratio on Frank's rew farm: x:40

since ratios are equivalent, you'd so the same on both sides. To get from 7 to 40 u multiply by a number, so to get from 10 to x u have to multiply by that same number. To find this number, divide 40 by 7: 40/7 = 5.7

Then, multiply this by 10: 5.7 x 10 = 57

there are roughly 57 pisquets on his farm.

### Answers

**Answer:**

14

**Step-by-step explanation:**

All of the angles are marked as congruent, which means it is an equlateral triangle. This means that all of the sides are congruent too.

Therefore z + 2 = 2z -10

add 10 to each side

z + 12 = 2z

subtract z from each side

12=z

now that we know that, we can plug it back in to either line (it doesn't matter because they're congruent)

line AB is z+2 which is 12+2 or 14

and line CB is 2z-10 which is 2(12)-10 or 24-10 which is also 14

so line CA is also 14 units long.

20. Rafael has a business selling computers. He buys computers from the manufacturer for $450

each and sells them for $800. Each month, he must also pay fixed costs of $3000 for rent and

utilities at his store. If he sells n computers in a month, which of the following equations can be used

to calculate his profit?

A. P = n(800 - 450)

B. P = n(800 - 450 - 3000)

C. P = 3000n(800 - 450)

D. P = n(800 - 450) - 3000

E. P = n(800 - 450) + 3000

Yeah

### Answers

**Answer: D , p = n (800 - 450) - 3000**

**Step-by-step explanation: Firstly, you have to account for how much money Rafael is making off of each computer (800 - 450). That factor is then multiplied by the variable "n" which represents the amount of computers sold. Lastly, since this is an equation to calculate his monthly profits, you have to subtract the rent that he is paying ($3000) from the total profit that he made off of selling the computers. Therefore, giving you the equation**

**P (profit) = n (amount of computers sold) (800-450) - 3000 (rent).**

The **equation **that represents Rafael's monthly **profit **selling 'n' numbers of computers is D. P = n(800 - 450) - 3000.

What is an equation?

An equation represents **equality **for the **terms **that are on the both side of the equal sign.

Given Rafael buys **computers **for 450 dollars and sells them for 800 dollars each.

He also had to pay 3000 dollars for **rent **and utilities for the store and the number of computers sold in each month is given by '**n**'.

∴ The equation that represents his profit(**P**) in a month is,

P = n(800 - 450) - 3000.

Write the equation. Solve for x.

### Answers

**Answer:**

X = 3

**Step-by-step explanation:**

First count the amount of X's. There are 5 and it is plus two. Both sides should be equal in value so you have to set up your equation.

5x + 2 = 17

Then Solve For X

5x + 2 = 17

Subtract 2 from both sides

5x = 15

Divide by 5

X = 3

Check your answer

5(3) +2 = 17

15 + 2 = 17

17 = 17
