????????????????????

the three angles of a triangle always add up to 180 degrees.

So, add the three angles together!

2x - 12 + 2x + 17 + 9x - 7 = 180

Group the similar numbers together.

13x -2 = 180

13x = 182

x = 14

Plug x in to 2x + 17

14*2 + 17 = 45

mX = 45 degrees

Answer:

m∠X = 45°

Step-by-step explanation:

All angles in a triangle add up to 180°

2x - 12 + 2x + 17 + 9x - 7 = 180

13x = 180 - 17 + 12 + 7

13x = 182

x = 14°

m∠X = 2x + 17

sub x = 14° into m∠X

2(14) + 17

m∠X = 45°

Answer: 4 seeds will left over.

Step-by-step explanation:

Total sunflower seeds = 1354

Number of people shared sunflower  seeds equally = 6

By division operation,

Number of seeds each people will get = (Total sunflower  seeds) ÷ (Number of people shared seeds equally)

[tex]= (1354) \div (6)[/tex]

[tex]=225\dfrac{4}{6}[/tex]

Hence, each people will get 256 sunflower seeds and 4 seeds will left.

Answer:

b

Step-by-step explanation:

Answer:

the first one

Step-by-step explanation:

y=3x+2

2x+y=-4

becomes

3x+2=y

2x+4=-y

add them

5x+6=0

5x=-6

x=-5/6

take x and replace it for one equation

y=-8/5

Answer:

they will meet 10 miles out after 2 hours

Step-by-step explanation:

Answer: A

Step-by-step explanation:

y-4 = -3/4(x+5)

y = -3/4x+1/4

Answer: the equation is y= 3/4 times + 1/4 is your answer

Answer:

62

Step-by-step explanation:

13-7=6

6 times 2=12

12 times 5=60

60 +2=62

hi

money he has  :   155 *8  =     800 + 440  =  1240

SO  1240 / 188 ≈ 6.59

so answer  is  6  as you cannot buy half books...

Answer: 6 hard cover books

Step-by-step explanation:

$155 x 8 =1,240

$188 x 6 = 1,128 which is as close as you can get without going over

Answer:

D. 1

Step-by-step explanation:

Distribute the -1

5x - 4x +1 = 2

1x = 1

x=1

next question

11)

[tex] {x}^{2} + (k - 1)x - k = 0[/tex]

[tex](x - 1)(x + k) = 0 \\ x = 1 \\ x = - k[/tex]

they are equal so both are one

then k = -1

be careful the answer of q 10 is in the pictures

Answer:

its 6

Step-by-step explanation:

(16x+5) = 1

50 - 45 = 5

5+1=6

Answer:

x=5

Step-by-step explanation:

since both triangles are equivalent then both given angles add up to 95. So to find x you would see what value makes it equal 85 when it's plugged in to equal 180 in total.

16(5)+5=85+95=180

Answer:

a) 4 products

b) 10 products

Step-by-step explanation:

When completing an online shopping transaction, a typical shopper takes 5 seconds to select each product and another 28 seconds to complete the check-out process.

For 1 product, the total time =

5 seconds + 28 seconds = 33 second.

We can derive an equation

Total time of transaction = 5x + 28

Where x is the number of products you are selecting

a) If it takes 48 seconds to complete a transaction, how many products are being purchased?

Total time = 5x + 28

48s = 5x + 28

5x = 48 - 28

5x = 20

x = 20/5

x = 4 items

b) If it takes 80 seconds to complete a transaction, how many products are being purchased?

Total time = 5x + 28

80s = 5x + 28

5x = 80 - 28

5x = 52

x = 52/5

x = 10 items

In whole number = 10 items

Answer:

The area of the triangle WYX  = [tex]\frac{35}{2}[/tex] = 17[tex]\frac{1}{2}[/tex]

Step-by-step explanation:

The area of the triangle WYX  is [tex]\frac{1}{2}[/tex]*b*h

We need to find base (b) and height (h)

By counting from the drawing, the base which is horizontal is 7 and the height which is vertical is 5

The area of the triangle WYX  is [tex]\frac{1}{2}[/tex]*b*h

The area of the triangle WYX  = [tex]\frac{1}{2}[/tex]*7*5 = [tex]\frac{35}{2}[/tex] = 17[tex]\frac{1}{2}[/tex]

Answer:

option d

Step-by-step explanation:

[tex]\frac{4}{9}[/tex] ÷ [tex]-\frac{5}{6}[/tex]

take reciprocal of -5/6,  [when you take reciprocal, the '÷' sign will become '×' sign]

⇒ [tex]\frac{4}{9}[/tex] × [tex]-\frac{6}{5}[/tex]

⇒ 4 × -6 / 9 × 5

⇒ [tex]-\frac{24}{45}[/tex]

⇒ [tex]-\frac{8}{15}[/tex]

therefore, option d is the correct option

Answer:

5.08 inches

Step-by-step explanation:

Alyssa used a scale in which 1 inch represents 100 feet. If the actual landmark has a height of 508 feet, find the height of Alyssa's model in inches.

The scale =

1 inch = 100 feet

100 feet = 1 inch

508 feet = x inches

Cross Multiply

100 × x = 508 × 1

x = 508 × 1/100

x = 5.08 inches

The height of the model is 5.08 inches
