When solving equations that have only one type of variable, you just get the variable on one side and the numbers on the opposite side.
6x + 7 = 8x - 13
Let us get the x on the left side.
Subtract each side of the equation by 8x.
6x + 7 = 8x - 13
-2x + 7 = -13
Subtract 7 from each side of the equation.
-2x = -20
Divide both sides by the coefficient of x. Which is -2.
x = 10
So, x is equal to 10 for this equation.
Answer:
The probability is 2/5
Step-by-step explanation:
Here, we want to calculate the probability that the first person will sit in a yellow roller coaster car
The number of cars to select from is 6 + 9 = 15 cars
The number of yellow cars is 6
So the probability that the first person selects a yellow roller coaster car to seat is 6/15 = 2/5
The best measure of center is 8
Answer: The answer would be 8.
Step-by-step explanation: I'm going to assume you mean 7 8/13 is a mixed fraction. So you multiply the denominator, 13, multiply 7 to that, then add 8 to it and the denominator would be the same as before. That should give you 99/13. When you divide, you get around 7.6, rounding closest to 8.
Answer:
If the 2 numbers are the same, it will be zero. If the positive number is larger than the negative number, the sum will be positive. If the negative number is larger than the positive number, then the sum will be a negative number.
