Arabica coffee costs $28 per pound and Robusta coffee

Mathematics

Answer:

1.62 pounds

Step-by-step explanation:

Let x be the pounds of Arabica

Take the number of pounds times the cost of each of the coffees individually

This must be equal to the number of pounds times the cost together

x * 28 + 8.75 *3 = ( x+3) 15.50

28x+26.25=(x+3)15.50

Distribute

28x+ 26.25 = 15.50x + 46.50

Subtract 15.50x from each side

28x-15.50x +26.25 = 15.50x +46.50-15.50x

12.50x + 26.25 = 46.50

Subtract 26.25 from each side

12.50x +26.25-26.25 = 46.50-26.25

12.50x = 20.25

Divide each side by 12.5

12.5x/12.5 = 20.25/12.5

x =1.62

Order these fraction from to : 2/3 , 7/12 , 3/4
lora16 [44]

I didn't really know whether to do it from least to greatest or greatest to least, so I did it from least to greatest.

Steps:

1. Find a common denominator

Let's do 12

2. Convert

7/12 is already in its simplest form, so 2/3 = 8/12 and 3/4 = 9/12

3. Order

7/12, 8/12, 9/12

4. Back to original form

7/12, 2/3, 3/4

ANSWER: 7/12, 2/3, 3/4

likoan [24]

Answer:

a + 8

Step-by-step explanation:

Note that

(x + y)² = x² + 2xy + y²

           = x² + y² + 2xy

           = a + 2(4) = a + 8

HELP ASAP!!! THANK YOU!!!
alex41 [277]

Answer:

Additional information required is

<DBA = 90°

Step-by-step explanation:

<DBA + <DBC = 180° [Linear pair]

=> <DBA = 180° - <DBC

=> <DBA = 180 - 90

=> <DBA = 90

Hence, both the angles <DBA = <DBC = 90°

As we know that when a perpendicular bisector bisects a straight line both the angles should be,

180° ÷ 2 = 90°

And above conditions also prove that

<DBA = <DBC = 90°

<em><u>Hence, DE is a perpendicular bisector of AC </u></em>
