Answer:
15 terms
Step-by-step explanation:
There is a common difference d between consecutive terms
d = 20 - 10 = 30 - 20 = 10
This indicates the sequence is arithmetic with n th term
= a₁ + (n - 1)d
where a₁ is the first term and d the common difference
Here a₁ = 10 and d = 10 with = 150 , then
10 + 10(n - 1) = 150 ( subtract 10 from both sides )
10(n - 1) = 140 ( divide both sides by 10 )
n - 1 = 14 ( add 1 to both sides )
n = 15
The number of terms is 15
6, -4, 2
You can get this by factoring the trinomial and setting each part, along with x-6, equal to 0. The trinomial can be factored to (x+4)(x-2)
The answer is 5 39/100
5.39 as a fraction is 539/100
To make that a mixed number you need to find out how many times the denominator goes into the numerator (100 goes into 539 5 times) so your whole number is 5 and you're left with 39/100 as the fraction, which can't be simplified any more.
QR =12 because you set up a proportion 21/14=x/8 then cross multiply and get 14x=168 then you divide and get 12
