For this case we have a function of the form:
y = A * (b) ^ t
Where,
A: initial amount
b: growth rate
t: time
Substituting values we have:
y = 100000 * (1.10) ^ 4
y = 146410
Answer:
the value of his house at the start of 2018 is:
y = 146410
72000/12=6000 12 pools of equal volume, both start and end are in gallons so it's just basic division.
Answer:
Question 1: B = 0
Question 2: 23/2 or 11-1/2
Question 3: 663/6 or 110-3/6
Step-by-step explanation:
Question 1:
(-5²)+(9+4²)=5B
-25+9+16=5B
5B=-0
B=0/5=0
Question 2:
2-7/8×2-6/9×1-1/2
=23/8×24/9×3/2
=23/2
=11-1/2
Question3:
3-1/4×6-2/3×5-1/10
=13/4×20/3×51/10
=663/6
=110-3/6
Answer:
x=3
Step-by-step explanation:
This is a proportional equation:
Given: x/9=9/27
Cross-multiply: 27x=81
Divide: x=3
So x=3
Hey there!
Apply fraction cross multiply: if a/b = c/d , then a *d = b*c
2 ( 5x - 2 ) = ( 2x + 4 ) * 4
expand : 2 (5x-2 ) => 2*5x - 2*2 => 10x - 4
expand : ( 2x +4 ) * 4 => 2x * 4 + 4*4 => 8x + 16
10x - 4 = 8x+16
add 4 to both sides:
10x-4+4 = 8x+16+4
simplify :
10x = 8x + 20
subtract 8x from both sides:
10x -8x = 8x+20-8x
simplify:
2x = 20
Therefore:
x = 20 / 2
x = 10
Hope that helps!
