The telephone company offers two billing plans for local calls. Plan 1 charges $34 per month for unlimited calls and Plan 2 char
lawyer [7]

Answer:

more than 200 calls

Suppose number of calls = x

According to plan 1: Total monthly charge is $24

According to plan 2: Fix charge is $16 and $0.04 per call

cost of x's call = $0.04x

and monthly charge according to plan 2 = 0.04x + 16

a)  Plan 1 is more economical than plan 2.

0.04x + 16 > 24

solve it for x

.04x > 8

x > 200

b)   So,  if more than 200 calls are made then Plan 1 is more economical.

3 times what gives me a sum of 24? im trying to finish my homework so please help.
Leno4ka [110]
It is not a sum, it is a product.

3 times x = 24   (write equation)
           3x = 24  (isolate x by dividing the coefficient, 3, on both sides)
           /3     /3
             x = 8    (this i your answer)

Therefore 3 times 8 gives you 24.

Marianne draws a triangle with the dimensions shown, then she draws a second triangle in which the dimensions are divided by 2.
Dafna11 [192]

Answer:

1/4

Step-by-step explanation:

The equation for the area of a triangle: A = 1/2bh

If all of the dimensions are halved then A = 1/2(1/2*b)(1/2*h) = 1/8bh

1/8bh is 1/4 of 1/2bh.

What is −1/2 − (−4/5) = x<br><br> Please Help Its due in like 15 minutes
laila [671]

Answer:

x = 3/10

Step-by-step explanation:

−1/2 − (−4/5) = x

First, switch sides.

x = −1/2 − (−4/5)

You are subtracting a negative number. Subtracting a negative number means add a positive number.

x = -1/2 + 4/5

Now you are adding two fractions, so you need a common denominator. The LCD of 2 and 5 is 10.

x = -5/10 + 8/10

x = 3/10
