Answer:
3n+12
Step-by-step explanation:
(n+4)3=
3n+12
Just multiply the number and variable inside the parentheses by 3
This equals 365 i know that is not what you ask but this is what i know
To the nearest square foot is the same as to the nearest whole number. That would be 63.
Let's solve your system by substitution.
2x−2y=−4;2x+y=11
Rewrite equations:
2x+y=11;2x−2y=−4
Step: Solve2x+y=11for y:
2x+y=11
2x+y+−2x=11+−2x(Add -2x to both sides)
y=−2x+11
Step: Substitute−2x+11foryin2x−2y=−4:
2x−2y=−4
2x−2(−2x+11)=−4
6x−22=−4(Simplify both sides of the equation)
6x−22+22=−4+22(Add 22 to both sides)
6x=18
6x/6 = 18/6
(Divide both sides by 6)
x=3
Step: Substitute3forxiny=−2x+11:
y=−2x+11
y=(−2)(3)+11
y=5(Simplify both sides of the equation)
Answer:
x=3 and y=5
Answer:
4.6
Step-by-step explanation:
Formula: Range = highest value - lowest value
Step 1: List all the data in ascending order
1.8, 2.4, 3.5, 4.9, 5.2, 6.4
Step 2: Identify the lowest and highest number
Lowest number : 1.8
Highest number : 6.4
Step 3 : Substitute the values in the formula
Range = highest value - lowest value
6.4 - 1.8 = 4.6
