The numbers are 3 and 18
Step-by-step explanation:
Step 1: Given details are sum of numbers = 21, let the numbers be x and y. Form equations out of the given details.
⇒ x + y = 21 ---- (1)
⇒ y = 6x --------- (2)
Step 2: Substitute (2) in (1)
⇒ x + 6x = 21
⇒7x = 21
⇒x = 3
- Step 3: Find the value of y using x
⇒ y = 6 × 3
⇒ y = 18
Answer:
-0.5
Step-by-step explanation:
Plug it into your calculator and you get -0.5
10(2) = 20
20 x 3.39 = 67.8
So, the product of 3.39 and 10(2) is 67.8.
