I believe that n = 4. product means multiplication, and 12 is the answer of 3 times n.
Step-by-step explanation:
Answer:
x = 3 & y = 6
Step-by-step explanation:
4x = 12
12/4 = 3
x = 3
2y + 10 = 22
22 - 10 = 12
12/2 = 6
y = 6
5 is the correct answer kind sir
Answer:
Sₙ = 57/2 * (504 + 896) = 39900
Step-by-step explanation:
first multiple of 7 after 500 is: 72 *7 = 504
last multiple of 7 before 900 is: 128 *7 = 896
a₁ = 504
aₙ = 896
where n = 128-72 +1 = 57
sum of arithmetic sequence: Sₙ = n/2 * (a₁ + aₙ)
Sₙ = 57/2 * (504 + 896) = 39900
