Answer: n=3
Step-by-step explanation: 5n+3=18
18-3=15
15/5=3
Let, the number = x
So, x * 1/10 = 0.04
x = 0.04 * 10
x = 0.4
So, your final answer is 0.4
Hope this helps!
Answer:
8.8 tsp
Step-by-step explanation:
4/5=x/11
cross multiply
44=5x
44/5=x
x=8.8
Step-by-step explanation:
step 1. let's call the line in the middle y.
step 2. y = sqrt(5^2 + 7^2) = sqrt(74). pythagorean theorem.
step 3. x^2 + y^2 =100 (pythagorean theorem))
step 4. x^2 + (sqrt(74))^2 = 100.
step 5. x^2 = 100 - 74
step 6. x^2 = 26
step 7. x = sqrt(26). note: sqrt is the square root.
