12 bracelets in 3 hrs.....12/3 = 4 bracelets per hr

To solve this, we must see a ratio between 3 hours and 15 hours.

12/3=x/15
15 is 5 times larger than 3. Therefore, if we multiply 12 by 5, we will know how many bracelets Ana can make.

12×5= 60

Therefore, 60 bracelets can be made in 15 hours

Answer:

You may or may not need to include the units.

A = 18x - 18

P = 6x + 6

Graph is attached below. (2, 18)

Step-by-step explanation:

Substitute the information we need, "l" and "w", into the formulas.

l is for length, 6cm.

w is for width, (3x - 3)cm.

Use the formula for area of a rectangle.

A = lw

A = (6)(3x-3)cm²

A = (18x - 18)cm²  or 18x - 18

Use the formula for perimeter of a rectangle.

P = 2(l + w)

P = 2(6 + (3x - 3))cm

P = 2(3x + 3)cm

P = (6x + 6)cm  or 6x + 6

Linear equations are written in the form y = mx + b, so we do not need to factor or further simplify the formulas.

To graph, first turn the "m" value into a fraction form.

8 -> 8/1

6 -> 6/1

You need two points to graph each line.

For each equation, the first point is on the y-axis at the "b" value. Then use the "m" in the equation to count the number of units up (numerator) and to the right (denominator).

The solution is (2,18)

A robot is expected to filter pollution out of at least 350 liters of air and water. It filters air at the rate of 50 liters per
s2008m [1.1K]

Answer:

20W+50A\geq 350

Step-by-step explanation:

we are given that A robot is expected to filter pollution out of at least 350 liters of air and water.

Also It filters air at the rate of 50 liters per minute, and it filters water at the rate of 20 liters per minute.

The inequality for  number of minutes the robot should filter air (A) and water (W) to meet this expectations can be writte as follows:

20W+50A\geq 350

Hence the required inequality has been formulated.

If the third of 6 consecutive numbers is 12, what is their sum?
Oksana_A [137]

Answer:

75

Step-by-step explanation:

If the third of 6 consecutive numbers is 12, what is their sum?

6 numbers  = c-2, c-1, c, c+1, c+2, and c+3

The numbers become 10, 11, 12, 13, 14, and 15

Add that together and you get 75.
