Answer:
The van holds 18 students
The bus holds 24 students
Step-by-step explanation:
v = van b = bus
High School A
1v+10b = 258
High School B
8v+5b = 264
Multiply the second equation by -2
-16v - 10b = -528
Add this to the first equation
-16v - 10b = -528
1v+10b = 258
---------------------------
-15v = -270
Divide each side by -15
-15v/-15 = -270/-15
v =18
The van holds 18 students
Now we need to find the number the bus holds
1v+10b = 258
18 + 10b = 258
Subtract 18 from each side
18-18+10b = 258-18
10b=240
Divide each side by 10
10b/10 =240/10
b = 24
The bus holds 24
Answer:
4
Step-by-step explanation:
The diameter of a circle is 2 times the radius. (the diameter is the length from an outer point in the circle, to one directly across)
In this case, the radius is 2.
So, 2 x 2 = 4.
The diameter is 4.
-7d > 21
d < -3
Remember the sign flips when you multiply or divide by a negative number.
Standard Normal Distribution. As discussed in the introductory section, normal distributions do not necessarily have the same means and standard deviations. A normal distribution with a mean of 0 and a standard deviation of 1 is called a standard normal distribution.
Rainfall in July = 2.79 inches.
July has 31 days.
2.79 : 31 = x : 1 Set up the proportion
2.79 / 31 = x/1 Cross multiply and switch.
2.79*1 / 31 = x Do the division
0.09 inches = x Answer
