1. Sarah and Maya both need notebooks and pencils. The equation that represents Sarah's
purchases is y = 13- 3x. The equation that represents Maya's purchases is y = 7 -x. If y
represents the price of notebooks, and x represents the price of pencils, what are the prices of
the notebooks and pencils?
a) pencils: $4 notebook: $3 go to card 4
b) pencils: $6 notebook: $1 go to card 3
c) pencils: $3 notebook: $4 go to card 5
d) pencils: $1 notebook: $6 go to card 7
e) pencils: $4 notebook: $4 go to card 2

Answer:

3.5x=-6y636477374747 88

Given:

The price of bananas can be determined by the equation P=0.25n, where P is the price and n is the number of bananas.

To find:

The constant of proportionality

Solution:

We have,

[tex]P=0.25n[/tex]       ...(i)

where P is the price and n is the number of bananas.

Price P is directly proportional to the number of bananas. So,

[tex]P\propto n[/tex]

[tex]P=kn[/tex]            ...(ii)

Where, k is the constant of proportionality.

On comparing (i) and (ii), we get

[tex]k=0.25[/tex]

Therefore, the constant of proportionality is 0.25.

Answer:

The expression would be 8w

Answer:

Solving for x : x = 3y/5 - 6/5.              Solving for y : y= 5x/3 +2

Step-by-step explanation:

Solving for x: Solve for x  by simplifying both sides of the equation, then isolating the variable.

Solving for y: Combine 5/3 and x.

You didn't say which one to solve for so I put out both for you.

Hoped this helped!

Brainly, Please?

Answer:

a= -5

Explanation:

Rewrite the equation to be: 3^a=3^-1 / 3^4

Multiply by adding exponents :))

which would then be 3^a = 3^-5

Then, since the bases are the same then the a would equal negative (-) 5. :))

Hope this helps :)) Plz mark brainlest :))

Answer:

Stacy is incorrect. Dilations do not affect the angles of a given figure since dilations create parallel lines and the angles on parallel lines are congruent.

Answer:3.0%

Step-by-step explanation:

Answer:

3%

Step-by-step explanation:

Answer:

Step-by-step explanation:

First use distributive property: a(b + c) = a*b + a*c

3n - 6 = -8(6 + 5n)

3n - 6 = 6 * (-8) + 5n *(-8)

3n - 6 = -48 - 40n

Now add 40n to both sides

3n - 6 + 40n = -48 - 40n + 40n

43n - 6 = -48

Now add 6 to both sides

43n - 6 + 6 = -48 + 6

           43n = -42

               n = -42 /43

Answer:

0.98

Step-by-step explanation:

3n-6=-8(6+5n)

3n-6=-48-40n

3n=-48-40n+6

40n+3n=-42

43n=-42

n=0.98 (I rounded it)

Answer:

7

Step-by-step explanation:

5/8 x 7= 4 3/8

That's the closest you are going to get without going over.

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

Work Shown:

100 + 22x = 298

22x = 298-100  ........ subtracting 100 from both sides

22x = 198

x = 198/22 .............. dividing both sides by 22

x = 9

It will take 9 months for her to pay off the sofa.

She pays the original $100, and then on top of that, she pays an extra 22*x = 22*9 = 198 dollars since she paid $22 per month for 9 months. So this leads to 100+198 = 298 dollars total to help confirm our answer.

Answer:

I will do 4 questions and you can solve the rest I did.

Step-by-step explanation:

Answer:

3

Step-by-step explanation:

it's 3 because the number is infront of a variable

Answer:

A) 130°

Step-by-step explanation:

Angle UTV = angle YTX = 75°

Angle VTW = 55°

so UTW = 75 + 55

if this helps, please give brainliest if possible

Answer:

A

Step-by-step explanation:

∠ UTV = ∠ YTX = 75° ( vertically opposite angles )

∠ VTW = 55° ( angle at centre is equal to arc that subtends it )

Then

∠ UTW = ∠ UTV + VTW = 75° + 55° = 130° → A

Answer:

100% is 9, 55% is 4.95, 75% is 6.75.

Step-by-step explanation:

Suppose that 100% were [tex]x[/tex]. Then 30% is 27, so [tex]0.3x=27[/tex] and we can divide both sides by 0.3 to see that [tex]x=\frac{27}{0.3}=\frac{27}{\frac{3}{10}} = \frac{27\cdot 10}{3} = 90.[/tex] So 55% is [tex]0.55x = 0.55 \cdot 9 = 4.95[/tex] and 75% is [tex]0.75x = 0.75\cdot 9=6.75[/tex]. (Note that we can divide the value of a percentage by 100 - the same as moving the comma by two places to the left - to get the decimal value.)

Answer:

C

Step-by-step explanation:

[tex]\sqrt{3}[/tex] times [tex]\sqrt{3}[/tex] = 3 and [tex]\sqrt{3}[/tex] times x = [tex]\sqrt{3}[/tex]x

So that means that answer is 3+[tex]\sqrt{3}[/tex]x which is C
