If a car factory checks 320 cars and 12 of them have defects, how many out of 560 will have defects? Use proportions
Viefleur [7K]

Answer:

Total number number of cars which do not have defects = 539

and 21 are defected out of 560 i.e. 560 - 539 = 21

Step-by-step explanation:

Total cars checked by Car factory = 320

Number of defected cars = 12

The number of cars which do not have defects = 320 - 12 = 308

Total Number of cars = 560

So the equation becomes

\left[560\:\times \:308\right]\:\div \:320

⇒  \frac{560\times \:308}{320}

\mathrm{Multiply\:the\:numbers:}\:560\times \:308=172480

⇒  \frac{172480}{320}

\mathrm{Divide\:the\:numbers:}\:\frac{172480}{320}=539

⇒  539

Therefore, total number number of cars which do not have defects = 539

and 21 are defected out of 560 i.e. 560 - 539 = 21

4[5-8(4c-3)]=12(1-13c)-8
goblinko [34]

\boxed{c = -4}

First, we will use the distributive property (order of operations) to simplify the equation:

(4)(5) + (4)(−8(4c−3)) = (12)(1) + (12)(−13c)+ (−8) =

20 + (−128c) + 96 = 12 + (−156c)+ (−8)

Now, we will combine like terms to simplify the equation:

(−128c) + (20 + 96) = (−156c) + (12+ (−8) =

−128c + 116 = −156c + 4

Now we will add 156 to both sides, using inverse operations.

−128c + 116 + 156c = −156c + 4 + 156c =

28c + 116 = 4

Now we will subtract 116 from both sides:

28c + 116 − 116 = 4 − 116 =

28c = −112

Lastly, we will divide both sides by 28:

28c/28 = c

-112/28 = -4

The equation now looks like:

c = -4

Therefore, your answer is -4.
