Answer:

5 days

Step-by-step explanation:

Given

Damian

[tex]Base\ Items = 5[/tex]

[tex]Rate = 3[/tex] daily

Andrea

[tex]Rate =4[/tex] daily

Required [Missing from the question]

How long will they get the same number of items

Represent the number of items with x and the days with y.

So:

For Damian

[tex]y = Base\ Items + Rate * x[/tex]

[tex]y = 5 + 3 * x[/tex]

[tex]y = 5 + 3 x[/tex]

For Andrea

[tex]y = Rate * x[/tex]

[tex]y = 4* x[/tex]

[tex]y = 4x[/tex]

Equate both expressions.

[tex]4x = 5 + 3x[/tex]

Collect like terms

[tex]4x - 3x = 5[/tex]

[tex]x = 5[/tex]

Hence, they will have equal amount of items after 5 days

Answer:

Company A = $13

Company B = $12.73

Company B

Step-by-step explanation:

To determine the unit cost for each company, divide the price of chocolate by the number of pounds

Unit cost = price ÷ total pounds offered

Company A

$32.50 ÷ 2 1/2

$32.50 ÷ 5/2

$32.50 x 2/5  = $13

Company B

$35 ÷ 2 3/4

$35 ÷ 11/4

$35 X 4/11 = $12.73

$12.73 is less than $13. Company b has a lower price per pound

Answer:

a = 4

Step-by-step explanation:

just divide 24 by 6

a = 4

Hey there!

The correct answer is 50 degrees.

To do this, we can figure out all the angles in the triangle. We know one angle: 45 degrees. To find the angle above that angle, we can use the 95 degrees and use linear angles to figure out that missing angle.

A linear pair adds up to 180 degrees, which means that 95 + (missing angle) = 180. 95 + 85 = 180. Therefore, we have two of the three angles in the triangle.

In a triangle, the number of angles adds up to 180 degrees, which means that 45 + 85 + (angle across from x) = 180. 45 + 85 + 50 = 180.

Now we have all the angles in the triangle.

With that information, we can use vertical angles to solve for x. If there are two lines that intersect, the angles opposite eachother are always equal. The angle opposite of x is 50; therefore x is equal to 50 degrees.
