Ok so find 20% off and see if less tha 75
percent means parts out of 100
20% means 20/100=1/5
'of' means multiply
20% of 80=1/5 times 80=16
off means subtract
disctoun tof 16 is 80-16=64
64<75
how much left over
75-spent=left over
75-64=11
anwwer is $11 left over and enough money to buy
8x² + 64x = 0
8x(x + 8) = 0
8x = 0 or x + 8 = 0
x = 0 or x = -8
Answer: x = 0 or x = -8
Answer:
46 years 1 month
Step-by-step explanation:
Let us assume the investment is a simple interest investment
The simple interest formula is
A= P(1+rt)
Given
Principal p= $1400
Rate r= 7.75%= 7. 75/100= 0.0775
Final amount A = $6400
Time t=?
To find the time t let us substitute our values in the simple interest formula
6400= 1400(1+0.0775t)
6400= 1400+108.5t
6400-1400=108.5t
5000= 108.5t
t=5000/108.5= 46.08
t= 46.1 years
It will take approximately 46 years 1 month to get the amount
Answer:
The Pythagorean Triplet that has 5 is 3-4-5
Step-by-step explanation:
We can prove this using Pythagorean Theorem: a² + b² = c²
3² + 4² = 5²
9 + 16 = 25
25 = 25
Answer:
1630x+8
Step-by-step explanation:
I did it in my head, not that hard tbh, you can do it too, I believe in you(8 doesn't have an x so it's just there, doing nothing)
