how do i find x i don't understand

Answer:

i think it would be -3/125

Step-by-step explanation:

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

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!

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

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.

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:

10

Step-by-step explanation:

I think is 10 because they are different triangles but both with the same measure, as you can see both angles are the same [36] and both sides of the triangle too [6] so when you divide the base [20] by 2 , 20÷2=10

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:

124

Step-by-step explanation:

15 x 4=60

32 x 2=64

64+60=124

Rachel bought a total of 124 pencils.

A numerical expression is algebraic information stated in the form of numbers and variables that are unknown. Information can is used to generate numerical expressions.

To find the total number of colored pencils Rachel bought, you can multiply the number of packs she bought by the number of pencils in each pack. Since she bought 15 packs of colored pencils with four pencils in each pack, the expression would be:

15 packs × 4 pencils/pack = 60 pencils

To find the total number of glitter pencils Rachel bought, you can use the same process. Since she bought 32 packs of glitter pencils with two pencils in each pack, the expression would be:

32 packs × 2 pencils/pack = 64 pencils

To find the total number of pencils Rachel bought in total, you would add the number of colored pencils to the number of glitter pencils. The expression would be:

60 pencils + 64 pencils = 124 pencils

Hence, she bought a total of 124 pencils.

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°.
