Answer:
The number of fours divided by the total number of possibilities. If there are two fours and 8 spaces, the probability is 2/8 = 1/4.Step-by-step explanation:
Answer:
520 - 303.93 - (10.99 * 4) - 25.25 - 73.43x ≥ 0
-
1) Parentheses
520 - 303.93 - 43.96 - 25.25 - 73.43x ≥ 0
-
2) Combine like terms
146.86 - 73.43x ≥ 0
-
3) Get the variable term alone
-73.43x ≥ -146.86
-
4) Divide to solve
x ≤ 2
** dividing by a negative number, the inequality sign flips **
ANSWER :
x ≤ 2
Answer:
a=-9 b=-5
Step-by-step explanation:
a(3-x) = - 2x+b
a3 - ax = - 2x+b
a3 - 2a = - 4+b
If you take a=-9
-27+18=-4+b
b= -5
Answer:
3.7
Step-by-step explanation:
To change a fraction to a decimal, just divide the numerator with the denominator. Instead of placing the remainder over the divisor, continue to solve until it is answered (unless it's a repeating decimal.)
Divide 7 with 10:
7/10 = 0.7
Remember that there is a whole number, 3. Add that to the decimal you have gotten:
3 + 0.7 = 3.7
3.7 is your answer.

To solve this problem, simply use one variable to represent the number of students in each of the 2 classes.
1st class - X = no of students
2nd class - X + 6 no of students
Both classes : X + X + 6 = 50
2X + 6 = 50
2X = 44
X = 22.
1st class - X = 22 students
2nd class - X + 6 = 22 + 6 = 28 students.
There are 28 students in the larger class.
