if you have 18 donuts that cost 50 cents. how much was two donuts?

Answer:

y = -3x + 2

Step-by-step explanation:

y = mx + b

m = rise/run = -6/2 = -3

(negative graph = negative slope)

b = y-intercept = 2

Answer:

y= -3x+2

i hope this helps :)

Answer:

Step-by-step explanation:

Using elimination means you either add the two equations together or subtract them. You can first multiply the second equation by 2, so you get 4x - 6y = 24. Then you add the two equations together to get 9x = 42. Then you solve for x and then you can solve for y.

7 packages = 28 dollars, do 1 package = 4 dollars

2 cookies in one package, so 2=$4, so a cookie is 2 dollars

Answer:

it's 2 1/2 so D

Step-by-step explanation:

it's not in the negatives so that immediately gets rid of B and C, and it's not past the number 3 so it's not A. it's in the middle of 2 and 3 which marks it as 2 1/2.

Answer:

y=-2/1+10

Step-by-step explanation:

Slope form is y=mx+b and the slope is negative due to the line going left and the y intercept is 10 because that is where the line goes through on the y axis

Answer:

279 ft²

Step-by-step explanation:

A=bh

A=16x16

A=256

Subtract the area of island

A=bh

A=3x7

A=21

256-21=235

Then you have to find the area of the trapezoid at the top, which is a reactangle and then two smaller triangles

A=bh

A=10x4

A=40

A=1/2bh

A=4x1x1/2

A=2

Multiply it by two because there are 2 of them

2x2=4

40+4=44

The area of the main part is 235 and the area of the side section is 44.

Add them together

235+44=279 ft²

Special right triangle

this is a 45, 45, 90 triangle

Meaning that whatever the hypotenuse is

that it will be the same for x

Answer:

10.9451≈10.9 feet

Step-by-step explanation:

sinT= hypotenuse/ opposite = x/5.8

sin32= x/5.8

x*sin 32=5.8

x=5.8/sin 32= 10.9451≈10.9 feet

Answer:

Norma ate [tex]\frac{9}{32}[/tex] of the leftover cake at her lunch.

Step-by-step explanation:

Norma had a leftover cake from her party = [tex]\frac{3}{8}[/tex]

She ate [tex]\frac{3}{4}[/tex]th of the leftover cake at the lunch.

Therefore, amount of cake she had at lunch = [tex]\frac{3}{8}\times \frac{3}{4}[/tex]

                                                                          = [tex]\frac{9}{32}[/tex] of the leftover cake

Norma ate [tex]\frac{9}{32}[/tex] of the leftover cake at her lunch.

Step-by-step explanation:

A scale factor of anything less than 1 is a reduction

A scale factor of anything more than 1 is an enlargement

Answer:

A:reduction

Step-by-step explanation:

If you multiply anything by 1/2 its size will become half as big. Example say you multiplied 4 by 1/2 you would only get 2, because 2 is half of 4.

Answer:

x=13

Step-by-step explanation:

For a to be parallel to b, 7x-26 + 9x-2 would have to = 180.

If we solve this equation,

16x-28=180

16x=208

x=13

x would have to equal 13 for a || b.

Answer:

x=13

Step-by-step explanation:

7x-26+9x-2=180

16x-28=180

16x=208

208/16=x

13=x

Answer:

missing angle = 67.8 degrees

Step-by-step explanation:

[tex]cos-1 = \frac{adjacent}{hypotenuse}[/tex]

[tex]cos-1 = \frac{5.3}{14}[/tex]

[tex]cos-1 = 0.378571428[/tex]

[tex]67.754 = 67.8[/tex]

C) 67.8° is the value of theta in the given right-angled triangle.

We know a right-angled triangle has three sides they are -: Hypotenuse,

Opposite and Adjacent.

We can remember SOH CAH TOA which is,

sin = opposite/hypotenuse, cos = adjecen/hypotenuse and

tan = opposite/adjacent.

Given, a right-angled triangle whose adjacent and hypotenuse are 5.3 and 14 respectively.

We know cos(theta) =  adjacent/hypotenuse.

∴ theta = cos⁻¹(adjacent/hypotenuse).

theta = cos⁻¹(5.3/14).

theta = cos⁻¹(0.3786).

theta = 67.8°.

In order:

x=35º, 50º, 91º, 118º, 42º, 104º, 112º, 130º, 40º

Step-by-step explanation:

For numbers 1,3,4,5, & 7, since the angles are same side interior, together they will add up to 180º. To find x, you subtract the given angle from 180º.

Example, #1: x=180-145, x=35º

For 2,6,8,9, since the angles are alternate interior, they will be congruent.

Example, #8: The given angle is 130º, so x will also be 130º.

I reccomend searching up alternate interior/exterior, same side interior/exterior, and corresponding angles on the internet.

Hope these are correct!
