Answer:
(3x+4)(2x-5)
Step-by-step explanation:
Factor by grouping.
Answer:
I don't remember the name of the law, but it states that when resistors are connected in series they put up one singular resistance. so,
Let smaller resistance be x
greater resistance is 3x
According to the question,
x+3x=12
4x=12
x=3
therefore,
resistors are of 3 ohms and 3×3=9 ohms
Answer:
Step-by-step explanation:
Let s and h represent the numbers of sodas and hotdogs sold, respectively. The problem statement tells you ...
... s + h = 165
... s - h = 39
Add these two equations to get ...
... 2s = 204
... s = 102 . . . . . divide by w
... h = 165 - 102 = 63 . . . . use the first equation to find h from s
The vendor sold 102 sodas and 63 hot dogs at the basketball game.
Change divide sign to multiplication sign, and flip second fraction
= 41/21 × 23/8
multiply top numbers together and multiply bottom numbers together
= (42×23)/(21×8)
=943/168
