Answer:
b=10, a=13
Step-by-step explanation:
let s number of yellow = a
number of blue = b
we have
a+b =23
2b - a = 7
->a+b +2b -a = 23+7
-> 3b = 30
->b = 10
->a = 13
You need to isolate x.
71 - 5x = 9x - 13
Add 13 to both sides.
84 - 5x = 9x
Add 5x to both sides.
84 = 14x
Divide both sides by 14.
6 = x
<h3>The answer is x = 6.</h3>
Step-by-step explanation:
20 1/2 = (20×2 + 1)/2 = 41/2.
to create 1/6 of that we have to multiply it by 1/6 :
41/2 × 1/6 = 41/12 = 3 5/12
the rock weighed 3 5/12 lb.
Jon spend 56 minutes in reading
<h3>What is Unitary Method?</h3>
Unitary method is a process by which we find the value of a single unit from the value of multiple units and the value of multiple units from the value of a single unit.
Jon spent 1 hour 17 minutes less than Camden
Camden spent 47 minutes less than Pete.
Pete spent 3 hours reading.
Since, pete spent 3 hours. So, Camaden spent
= 3 hours or (180 minutes) - 47 minutes
= 2 hours 13 minutes.
Now, Jon spent = 2 hrs 13 minutes - 1 hour 17 minutes
= 56 minutes
