there is no mistake

Step-by-step explanation:

this seems weird ik but i dont think there is even a mistake? the answer is definitely -7/2 or -3.5

Hi, I'm happy to help!

First, we need to use two variables. Let's use x and y for this example.

Let's use a Multiplication and Addition operation for our word problem.

Our expression can be something like this.

3x+y

Now, we form this into a word problem.

Joe and Jim are cousins. They are trying to see who can find the most apples. Joe picks x apples. Jim picks 3 times as many as Joe, and picks y extra. How many apples did Jim pick? Write and solve an expression representing the situation. x=10 and y=3

Here's how you would solve:

3x+y

(3×10)+3

30+3

33

Joe picked 33 apples.

I hope this was helpful, keep learning! :D

Answer:

Step-by-step explanation:

The catch here is to break up sqrt(6) into 2 parts that use primes to define sqrt(6)

sqrt(3)* sqrt(6)

sqrt(6) can be broken up into sqrt(2*3) which equals sqrt(2)*sqrt(3)

sqrt(3)*sqrt(2)(sqrt(3)

sqrt(3)*sqrt(3)*sqrt(2)

3*sqrt(2)

Answer:

Commutative Property of Addition

Step-by-step explanation:

3(x − 4) + 5x = 9x − 36

3x − 12 + 5x = 9x − 36  Distribute

3x + 5x − 12 = 9x − 36 Commutative Property of Addition

Answer:

Step-by-step explanation:

Common denominator is 45

(45/9)*2 = 10 and (45/15)*4 = 12

10/45 - 12/45 = - 2/45

Answer:

-3

Step-by-step explanation:

A postive and a negative becomes a negative.

So -3 + - 6 becomes

-3 - 6

= -9

The -9 is over 3, which is 9/3 negated, so 3 negated which is -3.

Answer:

D. 53,650

50,150+3,500=53,650

Answer:

61.84%

Step-by-step explanation:

Let the cost of the box be x. Since the price of the box and the pen is Rs 80, the pen's price can be represented as 80 - x. The box is sold at a ten percent profit, and an added ten percent is equal to 1.1. Therefore, the price the box sells at is 1.1(x). A 20% loss is the same a keeping 80% or multiplying by 0.8. This means the pen sold at 0.8(80 - x). Now, we are given the box went for Rs 28 more than the pen, so we can create an equation:

1.1x = 0.8(80 - x) + 28

We can simplify and solve:

1.1x = 64 - 0.8x + 28

1.9x = 92

x = 92/1.9

x = 920/19

The cost of the box after the increase would be 1.1(920/19) and the pen would be 0.8(80 - 920/19).

The sum of these two can be written as a percent x of 80.

80x = 0.8(80 - 920/19) + 1.1(920/19)

80x = 64 - 0.8(920/19) + 1.1(920/9)

80x = 64 - 0.3(920/19)

80x = 64 - 276/19

80x = 940/19

x = 940/1520

x = 0.6184

This is 61.84%

Answer:

h=4.5

Step-by-step explanation:

15-2h=6   Get rid of any constants of the side of the variable.

-15    -15

-2h=-9      Divide -2 from both sides to isolate h.

/-2  /-2

h=4.5

Answer:

0.575 ounce

Step-by-step explanation:

Total paint

= Green paint + white paint

= 1.6 ounces + 1.85 ounces

= 3.45 ounces

Paint in each part if divided into 6 parts equally

= 3.45 ounces/6

= 345 ounces/600

= 23/40

= 0.575 ounce

The amount of green and white paint in each part is 0.27 ounces and 0.31 ounces respectively.

The ratio is the division of the two numbers.

Proportion is the relation of a variable with another. It could be direct or inverse.

Given that,

Amount of green paint = 1.6 ounces

Amount of white paint = 1.85 ounces

Total paint = 1.6 + 1.85 = 3.45

The ratio of green paint to total paint = 1.6/3.45 = 0.46

Now, this ratio must be maintained in each part after dividing it into 6 equal parts.

Total paint in each section after dividing = (1.6 + 1.85)/6 = 0.58

With the same ratio,

Green paint / Total paint = 0.46

Green paint / 0.58 = 0.46

Green paint  = 0.27 ounces

White paint = total paint - green paint

White paint = 0.58 - 0.27 = 0.31 ounces

Hence "The amount of green and white paint in each part is 0.27 ounces and 0.31 ounces respectively".

just subtituted the remaining values of x.

Answer:

x= -1 —> y= –8

x=0 —> y= –9

x=1—> y= –10

x=2—>y= —11

Step-by-step explanation:

x= -1 —>y= -(-1)-9= +1-9 = –8

x=0 —> y= -(0)-9= –9

x=1—> y= -(1)-9= -1-9= –10

x=2—>y= -(2)-9 = —11

Answer:

92

Step-by-step explanation:

2 [3 (7-5) + 4 (8 + 2)]

= 2 [3 × 2 + 4 × 10)]

= 2 [ 6 + 40 ]

= 2 × 46

= 92

Answer:

Ok, so:

-The number of people who like tea are represented in the first column.

-The number of people who dislike tea are represented in the second column.

-The number of people who like coffee are represented in the first row.  

-The number of people who dislike coffee are represented in the second row.

This works like a multiplication chart:

People who like tea and coffee are represented in the top left square. People who dislike tea and coffee are represented in the box that coordinates to T' and C' (If you find T' and C' and run your fingers along the column/row until they run into each other, you'll find it.) The same is true for other combinations.

At the bottom of the first column is the total number of people who like tea. At the right-most part of the first row, is the total number of people who like coffee.

(52 people like tea, 80 people were surveyed)

I hope this helps you understand, please ask any clarifying questions you need! : )

Answer: 4x² + 4xy - 3y²

Concept:

When encountering questions that ask for simplifying algebraic expressions, using the FOIL method would be easier:

Solve:

Given

(2x - y) (2x + 3y)

Expand parentheses and apply the FOIL method

=4x² + 6xy - 2xy - 3y²

Combine like terms

=4x² + (6xy - 2xy) - 3y²

=[tex]\boxed{4x^2+4xy-3y^2}[/tex]

Hope this helps!! :)

Please let me know if you have any questions

the answer is 47yd²

hope it help n please give me brain.. thanks

Step-by-step explanation:

numbers

first = X

second = (x-10)

Third = 4(x-10)

x + (x-10) + 4(x-10) = 124

2x -10 + 4x-40 =124

6x - 50 = 124

6x = 124 + 50

6x = 174

x= 29

therefore the ;

first number = 29

second = (x-10) = 29-10 = 19

third= 4(x-10) = 4(29-10)= 76

Answer:

-1/2 , -1, -3/2

Step-by-step explanation:

1.)log base 16 1/4

log base 16 [tex]4 ^{-1 }[/tex] =x

[tex]16 ^{x} = 1/4[/tex]

x = -1/2

2.)log base 7 ¹/7

log base 7  [tex]7^{-1}[/tex] = x

7^x = 7^-1

x = -1

3.)log base 4 ⅛

4^x = 1/8

[tex]2^{2x} = 2^{-3}[/tex]

2x = -3

x = -3/2

Answer:

Step-by-step explanation:

1. Let a = log16 0.25, then:

0.25 = 16 ^ a = 16^-0.5

So the answer is -0.5.

2. log7 1/7

1/7 = 7^-1

Answer is -1.

3.  log4 1/8

1/8 = 4^(-1.5)

Answer is -1.5

Answer:

answers below

Step-by-step explanation:

1.  21.50n (Print it)

2. 70+18n (Top Print)

3. This one is more complicated. First, you find out the cost from each store, by inserting 30 in place of n. (1. =645), (2.=610). Then, you subtract 610 from 645, which gets your difference to 35$.

4. There is an error in the wording, but the answer should be something along the lines of this. "Bill would need to buy 2 fewer shirts from Print It than from Top Print for Print it to be cheaper."

Answer:

1). [tex]x = \frac{8}{7} [/tex]

2). [tex]x = - \frac{45}{2} [/tex]

Step-by-step explanation:

1) [tex]10 - \frac{1}{2} x = 6 + 3x[/tex]

[tex]20 - x = 12 + 6x[/tex]

[tex]20 - x - 6x = 12 + 6x - 6x[/tex]

[tex]20 - x - 6x = 12[/tex]

[tex] - x - 6x = 12 - 20[/tex]

[tex] - 7x = 12 - 20[/tex]

[tex] - 7x = - 8[/tex]

[tex]x = \frac{8}{7} [/tex]

•■•■•■•■•■•■•■•■•

2) [tex]x = - \frac{45}{2} [/tex]

[tex] \frac{1}{2} x - \frac{1}{4} = \frac{3}{5} x + 2[/tex]

[tex]20( \frac{1}{2} x - \frac{1}{4} ) = 20( \frac{3}{5} x + 2)[/tex]

[tex]20 \times \frac{1}{2} x - 20 \times \frac{1}{4} = 20( \frac{3}{5} x + 2)[/tex]

[tex]10x - 20 \times \frac{1}{4} = 20 \times \frac{3}{5} x + 20 \times 2[/tex]

[tex]10x - 5 = 20 \times \frac{3}{5} x + 20 \times 2[/tex]

[tex]10x - 5 = 4 \times 3x + 20 \times 2[/tex]

[tex]10x - 5 = 4 \times 3x + 40[/tex]

[tex]10x - 5 - 12x = 40[/tex]

[tex]10x - 12x = 40 + 5[/tex]

[tex] - 2x = 40 - 5[/tex]

[tex] - 2x = 45[/tex]

[tex]x = - \frac{45}{2} [/tex]
