Answer:
Just substitute, and the simplified form is 1
Step-by-step explanation:
Substitute the values needed into the original equation. For example, if n=1
t(1)=15-2.5(1)=15-2.5=12.5. Or, if tn+1 substitute f(tn+1)=15-2.5(tn+1) and simplify.
tn+1-tn in its simplest form is just 1, as tn and -tn cancel out to leave 1.
Answer:
x=5.5
Step-by-step explanation:
Perimeter of ABCD=85
The perimeter is everything around the outside added together.
Form an equation:
3x+4+4x+6x-11+5x-7=85
Collect the like terms:
Like terms are terms that have the same powers and coefficient.
3x+4x+6x+5x=18x
4-11-7= -14
Put it back into an equation:
18x-14=85
Do inverse operations to find out what x is:
85+14=99
18x=99
99÷18=5.5 (we divide because, in algebra, when a number is next to a letter, it means times and as we want the inverse, you would have to divide)
x=5.5
Hope this helps :)
Answer:
2 units^2
Step-by-step explanation:
The area of a triangle is given by the formula
A = 1/2 bh where b is the length of the base and h is the height
b = 2 and h =2
A = 1/2 (2) * (2)
A = 1/2*4
A = 2 units^2
6 marbles per person.
If we count the number of marbles in total, we get 24: 5+9+4+6= 24
Now that we know the Total # of marbles, we need to know how many people we need to distribute marbles to. We count Brian, Sarah, Jimi, and Juan and get 4 people in total.
To find how many marbles each person needs to receive, we then need to do 24 divided by 4.
When we do this, we get 6 marbles per person.
23000=X [((1+0.04/4)^(4*10)-1)/(0.04/4)]
Solve for x
X=470.48
