Answer:</h2><h2>The chance is 100 % since we have not seen it in the past three days.</h2>
Step-by-step explanation:
The odds of seeing a black cat are 25% every day.
It also means that the possibility of seeing a black cat is once in 4 days, since 25%
Given, we have not seen one black cat in 3 days.
The chance of seeing a black cat on the 4th day = ?
= 100 % since we have not seen it in the past three days.
Answer:
Step-by-step explanation:
Let
x ----> the length of Zach's car
y ----> the length of Ginny's car
we know that
The sum of the lengths of both cars is 30 inches
so
----> equation A
Ginny's car is 2 more than 3 times the length of Zach's car
so
----> equation B
substitute equation B in equation A
To solve linear equations, you can add them together.
2x+3y=3
7x-3y=24
9x=27
x=3
Then you plug in your answer in to solve for y.
2(3)+3y=3
6+3y=3
3y=-3
y=-1
So your answer is C.
12 more than 8.2 times a number n is the same as “8.2n + 12”.
