Ok so for the first one it’s super simple I’m gonna do it as less complicated so it can help you :)
So first we need to convert the mixed number to an improper fraction
1 4/5 = 9/5
Now we need to reduce the numbers greatest common divisor which is 3
3/5 x 6
Now multiply the numbers
Your answer is 18/5 I hoped this help
Now for the second one
this one is a little more complicated and I don’t know how to make it sound easier so I’m gonna tell you the answer which is 580/21
The last one is the same steps we did for the first one which is 27/20
I hoped this helped you it is a little difficult but you’ll get the hang of it :)
Answer:
b² + c² = 47
Step-by-step explanation:
Expand (b + c)² = 61
⇒ (b + c)(b + c) = 61
⇒ b² + 2bc + c² = 61
Substitute bc = 7 into b² + 2bc + c² = 61:
b² + 2(7) + c² = 61
b² + 14 + c² = 61
To determine b² + c² simply subtract 14 from both sides of the equation:
b² + c² = 47
Answer:
x = 24
Step-by-step explanation:
x/4 + 10 = 16
x/4 = 16 - 10
x/4 = 6
x = 6 · 4
x = 24
