Answer:

75% of the original paper’s size.

Step-by-step explanation:

Let’s say that the original size was 10 inches.

You then increase it by 50%. It is now 15 inches.

Now, you decrease it by 50%. 50% of 15 is 7.5. So, the paper is now 7.5 inches.

7.5 inches is 75% of the original paper size.

I hope I helped!

Let me know if you need anything else!

Convert 14x + 6y = 36 to slope intercept form.
zubka84 [21]

Answer:

y = - \frac{7}{3} x + 6

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c

Given

14x + 6y = 36 ( subtract 14x from both sides )

6y = - 14x + 36 ( divide all terms by 6 )

y = - \frac{14}{6} x + 6, that is

y = - \frac{7}{3} x + 6 ← in slope- intercept form

Lamar's Coffee Shop makes a blend that is a mixture of two types of coffee. Type A coffee costs Lamar $4.40 per pound, and type
Firdavs [7]

Answer:

Lamar used 76 pounds of type B coffee

Step-by-step explanation:

Let x = the number of pounds of type A coffee

Let y = the number of pounds of type B coffee

Type A coffee costs Lamar $4.40 per pound, and type B coffee costs $5.60 per pound. This means total cost of type A coffee and type B coffee will be

$(4.4x + 5.6y)

This month, Lamar made 129 pounds of the blend, for a total cost of $658.80.

This means the sum of type A coffee and type B coffee for the month is 129 and the total cost is $658.80

The equations deducted are

x + y = 129 - - - - - - - - -1

4.4x + 5.6y = 658.80 - - - - - - - - - - 2

Substituting x = 129 - y in equation 2,

4.4(129 - y) + 5.6y = 658.80

567.6-4.4y + 5.6y = 658.80

-4.4y + 5.6y = 658.80 - 567.6

1.2y = 91.2

y = 91.2/1.2 = 76 pounds

x = 129-y = 129-76

= 53 pounds

Lamar used 76 pounds of type B coffee
