Solve for x. 7(x - 3) = 4(x + 5) x =1/11 x =1/3 x =41/11 x =41/3
marin [14]
To solve for the x, distribute first the numerical coefficients to the terms on the parentheses. This becomes,
   
                                          7x - 21 = 4x + 20

Transpose all the terms with x and the constant on either sides of the equation,
 
                                           7x - 4x = 20 + 21
  
                                        3x = 41   ;    x = 41 / 3

Thus, the answer is x = 41/3 which is fourth among the choices.

A phone company charges $0.06 per minute for local calls and $0.15 per minute for international calls. When your bill comes, it
solmaris [256]
Let's assume two variables x and y which represent the local and international calls respectively. 

x + y = 852 = total number of minutes which were consumed by the company (equation 1)
0.06*x+ 0.15 y =69.84 = total price which was charged for the phone calls (Equation 2)
 from equation 1:-
x=852 -y (sub in equation 2)
0.06 (852 - y) + 0.15 y =69.84

51.12 -0.06 y +0.15 y =69.84 (subtracting both sides by 51.12)
0.09 y =18.74
y= 208 minutes = international minutes (sub in 1) 
208+x=852 (By subtracting both sides by 208)
x = 852-208 = 644 minutes = local minutes

. Evaluate the following: |15 - 47] + 9 - (-2)(-4) - 17|
alexdok [17]

Answer:

48

Step-by-step explanation:

Since there is an absolute value, the answer must be positive. Multiply 2 by 8 since two negatives equal a positive. So, |15-47 + 9 - 8 -17|. Then add and subtract to get the answer. -32 + 9 - 8 -17 = -48. |-48| = 48
