Answer:
First number =26
Second number =49
Step-by-step explanation:
Question:
The sum of two numbers is 75. The second number is 3 less than twice the first. Find the numbers.
Given:
Sum of two numbers = 75
The second number is 3 less than twice the first.
To find the numbers.
Solution:
Let the first number be = 
Let second number be = 
The sum equation can be given as:
It is given that the second number is 3 less than twice the first.
This can be given as:
Substituting the value of in terms of in the sum equation.
Combining like terms.
Adding 3 both sides.
Dividing both ides by 3.
Substitution in the second equation to find .
Thus, first number =26 and second number =49.
Note that a percentile tells us how many percents of numbers that are above the number at the percentile. So the 70th percentile tells us that 70% of the students are taller than Jake. That means 30% of the students are either at the same height or shorter than Jake.
30% of 1100 would be 0.3*1100 = 330.
So there are 330 students that are either at the same height or shorter than Jake.
Answer: 2.4 * 10^1
Step-by-step explanation:
Divide the two numbers. 4.8 * 10^3 = 4800
4800/200 = 24
Put into scientific notation
24 = 2.4 * 10^1
4.8 * 10^3 is 24 (2.4*10^1) times greater than 200
Answer:
y=-4x+18
Step-by-step explanation:
y=-6(x-3)+2x
Distribute -6 to the (x-3)
y=-6x+18+2x
Combine like terms
y= -4x+18
