To do this, you'll have to get loris and doris to the same amount of time, we can already tell loris makes 40 bracelets in 100 minutes but we are still missing 20 minutes, so we got to do some math(Ofc we do its mathematics) if you divide 50 by 20 you'll get 2.5 which is how many minutes it takes to make a bracelet. So now we can go back to that missing 20 minutes, if you divide 20 by 2.5, you'll get 8. So in 2 hours loris makes 48 bracelets(20 + 20(50 hours each)=40 + 8(the missing 20 minutes) = 48) But here is the tricky part it says per an hour, so we need to reduce both by half, so loris makes 24 bracelets an hour and doris makes 22 bracelets an hour so loris makes 2 more bracelets and hour than doris... hope i've helped!
Pasa 96 veces. Porque cuando en una hora ahí 4 múltiples de 3. Tu coges las 4 vez es I lo multiplica a 24 horas. Así es como yo resulte con el número 96.
So,
The secret to solving problems with ratios is to find the value of one unit.
5:7 = 12 units total
To find one unit, divide the total number of students by the total number of units.
600/12 = a
Simplify
50/1 = a
50 = a
The value of each unit is 50.
Now, multiply the units by the numbers in the ratio.
50(5) = b
250 = boys
50(7) = x
350 = x
There are 350 girls.
Answer:
The answer is B
Step-by-step explanation:
I got a giid grade
4x + 5 5x 4x + 5 - 5x -x + 5
---------------- - ---------------- = ------------------ = -------------------
6x^2 - x - 12 6x^2 - x - 12 6x^2 - x - 12 6x^2 - x - 12
