Answer:25x + 5

Step-by-step explanation:

(5x * 2 + 3x - 7) + (12x +12)

= (10x +2x - 7) + (12x + 12)

= (13x - 7) + (12x + 12)

Expand the brackets

= 13x - 7 + 12x + 12

Join like terms together

= 13x + 12x + 12 - 7

= 25x + 5

Tanya [424]

Answer:

c. 0.810

Step-by-step explanation:

Given, total % of satisfactory packages = 90% = 0.90

Now, since selecting a satisfactory package is independent of any other trials (i.e. all the selection trials are independent to each other)

Hence, Probability of selecting two packages that re satisfactory

P(Selecting 2 satisfactory packages) = (0.90)^2

P(Selecting 2 satisfactory packages) = 0.90*0.90

P(Selecting 2 satisfactory packages) = 0.810

Note: We are selecting product since the chance of selecting in each trials are independent.

Cars are made in a factory at a rate of 39 cars every 3hours at this rate, how many cars can be made on the factory in 7 hours
Mumz [18]

Answer:

Step-by-step explanation:

39 cars every 3 hrs.......that means (39/3) = 13 cars every hr

and if its 13 cars every hr....in 7 hrs, there will be (7 * 13) = 91 cars <==

you can either do it that way....the unit rate way...OR

you can set it up as a proportion...

39 cars to 3 hrs = x cars to 7 hrs...

39 / 3 = x / 7....cross multiply

(3)(x)= (39)(7)

3x = 273

x = 273/3

x = 91 <====

either way, u get the correct answer
