Mai’s kitchen table measures 4 cm by 2.5 cm on the scale drawing.

Answer: −y^2+18y

Let's simplify step-by-step.

5y(4−(y+2))+4y(y+2)

Distribute:

=(5y)(4)+(5y)(−y)+(5y)(−2)+(4y)(y)+(4y)(2)

=20y+−5y2+−10y+4y2+8y

Combine Like Terms:

=20y+−5y2+−10y+4y2+8y

=(−5y2+4y2)+(20y+−10y+8y)

=−y^2+18y

Answer:

= −y^2+18y

Hope this helps you!

No(0)Let the cost price of the 20 pens be ₹100.

Cost of each pen=₹100/20=₹5

Selling price of each 25 pens sold=₹100/25=₹4.

%LOSS:

If cost of each pen. = 5=100%

..selling price of each pen. = 4= ?%.

Cross multiply:5? =400

?=80%

So,%loss= 100%-80%=20%

Step-by-step explanation:

(-2+6)/2 (2+4)/2

Answer:

Yes, it matters which way you subtract values because if you subtract a larger number from a smaller number you will get a negative nummber, but when you subtract the smaller number from the bigger number you get a positive number

ex: 5-6= -1 but 6-5=1

Step-by-step explanation:

Answer:

32 + 4x ≤ 50

Step-by-step explanation:

Cost of tickets = $32

Cost of soda = $4

Total spent = $50

When we say "no more than", we mean less than or equal to (≤)

He buys 1 tickets and x sodas

32 + 4x ≤ 50

4x ≤ 50 - 32

4x ≤ 18

Divide both sides by 4

x ≤ 18 / 4

x ≤ 4.5

Shawn can buy more than 4 sodas

Answer:

0.09 and 0.04

Step-by-step explanation:

The probability that a randomly-selected person at a show has seen the band play live before is 30%=0.30

The probability that a person at a show is a "superfan" is 20%=0.20

Two people are selected at random.

The probability that both people have both seen the band perform live before  = The probability that the first person has seen the band live before and the second person also has seen the band live before.

=0.30 x 0.30

=0.09

Similarly, the probability that both are  "superfans"   = The probability that the first person is a superfan and the probability that the second person is a superfan.

=0.20 x 0.20

=0.04

Hence, the probability that both people have both seen the band perform live before, and are "superfans" are 0.09 and 0.04 respectively.

The required rate for granola in dollars per pound is 1.25.

In order to solve a problem for two different values of a quantity, its unit value is first derived. This method is known as unitary method.

Given that,

The total money spent on granola is $3.75.

And, the amount of granola is 3 pounds.

The unit rate for the given case can be found using unitary method as,

Money spent for 3 pounds = $3.75

Then, money spent for 1 pound = 3.75/3 = $1.25

Hence, the rate of granola $1.25 per pound.

Answer: 45=3a   a=15

Step-by-step explanation:

We know that Molly has $45 or 3 times the amount of money her brother has, and a represents the amount of money her brother has. So we would multiply a by 3. In order to find a we just divide 45 by 3.

Answer:

7^3 + 7^3 units^3

OR

(7^3)2 units^3

Step-by-step explanation:

Volume = length x width x height

In cubes, length = width = height

So, volume = 7 x 7 x 7 = 7^3

2 cubes:

7^3 + 7^3 units^3

OR

(7^3)2 units^3

Answer:

[tex]x=-8[/tex]

Step-by-step explanation:

[tex]\frac{x}2} -x=\frac{x}{4} +6[/tex]

Let's begin by getting rid of the fractions by multiplying both sides of the equation by the least common multiple of the denominators 2 & 4 (4).

[tex]4(\frac{x}2} -x)=4(\frac{x}{4} +6)[/tex]

Distribute:

[tex]\frac{4x}{2} -4x=\frac{4x}{4} +24[/tex]

Simplify:

[tex]2x-4x=x+24[/tex]

Combine like terms:

[tex]-2x=x+24[/tex]

Subtract [tex]x[/tex] from both sides of the equation:

[tex]-3x=24[/tex]

Divide both sides of the equation by the coefficient of [tex]x[/tex], which is [tex]-3[/tex]:

[tex]x=-\frac{24}{3}[/tex]

Simplify:

Answer:

d. 2.30 feet

Step-by-step explanation:

there are around 30 cm per foot so 70 cm translates to around 2.3 feet

Answer:

2.29 fr

Step-by-step explanation:

Convert cm to ft.

Answer:

We start with the equation:

(3 + 4x) + (2 -x) = 5 + 3x

Now we replace:

x = i

This is just changing all the "x"s in the equation by "i"s:

(3 + 4i) + (2 - i) = 5 + 3i

This can be viewed as 3 complex numbers:

z1 = 3 + 4i

z2 = 2 - i

z3 = 5 + 3i.

Now, let's check if equality remains true:

(3 + 4i) + (2 - i) = 5 + 3i

The first step is to use the associative and commutative properties to separate the real and imaginary parts.

(3 + 2) + (4i - i)

5 + (4 - 1)*i

5 + 3i

Then the equality remains true.

And this will be true always, for anything that we feed into the x in our initial equation:

(3 + 4x) + (2 -x) = 5 + 3x

This is because x is a variable, so it can be evaluated in any number, and the equality will still be true.

B. Domain: {1, 3.5, 5, 7.5, 9}

F. Range: {2, 6.50, 7.00, 9.00, 12.50}

Step-by-step explanation:

The set of input values make up the domain of the function, while the corresponding set of output values is the range of the function.

That is, the domain is the number of hours, while total cost is the total cost.

Domain would be: {1, 3.5, 5, 7.5, 9}

Range would be: {2, 6.50, 7.00, 9.00, 12.50}
