Answer:
1.benchmark fractions
2. equivalent fractions
Step-by-step explanation:
Hope it helps!
Take this example (cause it's easy to explain)
10+5x=15x
To solve it we have to minus five on both side. We have to do this because we need to isolate the variable (in this case x) on the one side so we can divide and solve.
You would -5x (inverse from positive 5) from both sides on this because whatever you do to one side you have to do to the others to make it equal. In this case the answer would be x=1 (again cause it's easy lol.)
I hope this helps you!
6x
x=10
So replace "x" in 6x with 10 and you get,
6(10)
It can be seen as
6 x 10
and 6 x 10 is 60.
So your answer would be 6x = 6(10) = 60
Answer:
A
Step-by-step explanation:
The n th term ( explicit formula) for a geometric sequence is
f(n) = a
where a is the first term and r the common ratio
Here a = 2 and r = - 8 ÷ 2 = - 4, thus
f(n) = 2
