8x+15=7
In the statement the phrase the sum of can tell you that it is going to be an addition problem. So 8x ( eight times a number) would be added to the 15, 8x+15. Since its an addition problem the part where it says ' ... is seven', you know that it will all equal 7. So the answer would be 8x+15=7.
You have to subtract do it will come out as 175. learn how to subtract big digets and then you will know how to do it tell your teacher that you need help with that.
In this problem, we're going to use the 'PEMDAS' method.
First, we're doing the problem in the parenthesis.
44 - 4 = 40
Next in PEMDAS, we need to do the exponent.
6² = 6 x 6 = 36
Then we would do multiplication, but there is nothing to multiply so we move onto division.
40 / 2 = 20
Now we would add, but there is nothing to add so we move onto subtraction.
20 - 36 = -16
Our final answer would be -16.
Hope this helps!~
Answer:
x = 7
Step-by-step explanation:
Since n>2 n
n can be 3 for example
so a3=t
and from the sequence we know a3 = 15
because it is the product of a1(3) and a2( 5)
so t = 15
