t = 5c
Each car needs 5 tires (4 on it and 1 spare, which add up to five). So for every one car they make they need 5 tires. Two cars would need 10 tires, 3 would need 15 tires, etc, so the number of tires can be found by multiplying the number of cars by 5. Putting this into equation form, you'd get t = 5c
The formula to calculate the number of tires needed in an automobile factory is t = (4c) + c, where t represents the number of tires needed and c represents the number of cars produced per day.
The formula to calculate the number of tires needed in an automobile factory is given by:
t = (4c) + c
Where t represents the number of tires needed and c represents the number of cars produced per day.
For example, if the factory produces 100 cars per day, we can substitute c = 100 into the formula to find that t = (4 * 100) + 100 = 500 + 100 = 600. Therefore, the factory would need 600 tires per day.

The probability that the spinner stops at purple and a pink card is selected is 80%.
We have given that,a spinner with 5 equal sectors is shown in the figure.
The spinner has a 1/5 chance of landing on purple, since the number of favorable outcomes is the numerator, and the number of possible outcomes is the denominator.
There are total four cards, which means we have a 1/4 chance of picking pink,
for the samereason as above.
Therefore 1/5 x 1/4 = 4/5
4/5 =0.80= 80% chance.

x+6=±5
Step-by-step explanation:
Carly's mistake occurred in Step 2. She incorrectly divided both sides of the equation by 7 instead of subtracting 2 from both sides.
Carly's mistake occurred in Step 2. In this step, she incorrectly divided both sides of the equation by 7 instead of subtracting 2 from both sides. Let's correct her mistake:
-4(7j+2) = 10
7j+2 = -40
7j = -42
j = -6
Instead of dividing both sides by 7, Carly should have subtracted 2 from both sides:
7j + 2 - 2 = -40 - 2
7j = -42
j = -6
Therefore, Carly should have subtracted 2 from both sides in Step 2 instead of dividing by 7.
