Answers

Answer 1

Answer:

C. $20

Step-by-step explanation:

Lets make our equation. "x" will be our first journal, and "4/5x + 12" will be our second journal. So our equation is: x + 4/5x + 12 = 30

Subtract 12 from each side: x + 4/5x = 18

Combine like terms : 1 4/5 x = 18

Divide each side by 1 4/5 : x = 10

Plug in x for the journals-

1 = 10

2 = 4/5 of 10 = 8 + 12 = $20

I hope this helped, please mark Brainliest, thank you!

Geometry help plz who ever gets correct will get brainlist promise!

Answers

Answer:

y=90⁰

Step-by-step explanation:

● 180⁰-110⁰=70⁰ (lines on a straight line)

70⁰+70⁰+x+x= 180⁰( sum of a triangle=180⁰)

2x=40⁰

x=20⁰

● 70⁰+20⁰+y=180⁰(sum of a triangle =180⁰)

y=180⁰-90⁰

y=90⁰

Angles of the triangle:

angle1 = 70°

angle2 = (x + x)°

angle3 = (180 - 110)°

By angle sum property of a triangle,

angle1 + angle2 + angle3 = 180°

Therefore,

70 + (x + x) + (180 - 110) = 180

70 + 2x + 70 = 180

140 + 2x = 180

2x = 180 - 140

2x = 40

x = 40/2

x = 20

Hence, x = 20°

It takes 10 pounds of potatoes to make 15 pounds of mashed potatoes. At this rate: How many pounds of potatoes are needed to make 50 pounds of mashed potatoes?

Answers

Answer:

Step-by-step explanation:

You need to set up a proportion.

10 pounds of potatoes/15 pounds of mashed potatoes

Before going on notice that the potatoes are on the top part of the fraction and the mashed potatoes are on the bottom. The right hand side of the proportion must be the same.

10 pounds potatoes/15 pounds mashed = x pounds / 50 pounds mashed.

The raw potatoes are on the top, The mashed is on the bottom. It's always like that.

The second step is to cross multiply.

10 / 15 = x / 50          Cross miultiply

10*50 = 15 * x            Combine the left

500 = 15x                  Divide by 15

500/15 = x

x = 33.33

Answer:

33.33

CAYB is a quadrilateral

BY= 5a-b

X is the point on AB such that AX:XB= 1:2

Prove that CX = 2/5 CY

Answers

Answer:

see explanation

Step-by-step explanation:

CY = CB + BY

     = 6b + 5a - b

     = 5a + 5b

---------------------

CX = CA + AX

     = CA + [tex]\frac{1}{3}[/tex] AB , find AB

AB = AC + CB

     = - 3a + 6b

     = 6b - 3a

Thus

CX = CA  + [tex]\frac{1}{3}[/tex] AB

      = 3a + [tex]\frac{1}{3}[/tex](6b - 3a)

      = 3a + 2b - a

      = 2a + 2b

---------------------

and

[tex]\frac{2}{5}[/tex] CY

= [tex]\frac{2}{5}[/tex] (5a + 5b)

= 2a + 2b = CX

Hence CX = [tex]\frac{2}{5}[/tex] CY ⇒ Proven
