Solve for the first variable in one the equations then substitute the result into the other equation so the answer is (2,5)
-1/5of 15 =-3 then add 3 2/5th which is 17/2 so -3+17/2 = 11/2=5 1/2

Answer:
P(compact cars) = 4/25
Step-by-step explanation:
We know that there are 13 trucks, 8 vans, and 4 compact cars.
Let P denotes the probability of an event
Now we are asked to find the probability of compact cars
Number of favorable events = number of compact cars = 4
total number of outcomes = 13+8+4 = 25
hence, P(compact cars) = number of favorable events/total outcomes
=4/25
Answer:
5×10⁻²
Step-by-step explanation:
- Move the decimal so there is one non-zero digit to the left of the decimal point.
- The number of decimal places you move will be the exponent on the 10. a. If the decimal is being moved to the right, the exponent will be negative.
b. If the decimal is being moved to the left, the exponent will be positive.
- Therefore. The answer is 5×10⁻²
