Salina was at a party and she noticed that the room had 54 balloons. For every red balloon there were 2 yellow balloons and 3 blue balloons. How many blue balloons were there?
how do i figure this when it doesnt tell me how many red balloons there are
your answer is A
well for starters we know that there are 54 balloons
ok now as you said we dont know how many red balloons we have so lets say we have x red balloons
and that the answer is A:)
Now for every 1 red balloon we have 2 yellow balloons so if we have 2 red balloons we will have 2*2=4 yellow balloons. So basically there are twice the amount of red ballons yellow balloons =2x
kelly stop texting stupid stuff that doesnt make sense
Now for every red balloon there are 3 blue balloons blue balloons=3x Now in total we will have x+2x+3x=54
Now can you solve for x to find out how many red balloons there are
so what did you get for x?
ok one sec
x=9 right
yup now we know that there are 9 red balloons
so how many blue balloons would there be?
27 :):):)
YAHHHOOOOOOOOO
At an amusement park, each premium ride costs $12 and each gold star ride is $8. Stan spends $96 on tickets and he gets 3 more premium rides than gold star rides. How much does he spend on gold star rides?
Lets see what @robtobey has to say. Maybe i did something incorrectly
27 blue balloons. There are 54/6=9 groups of red/yellow/blue balloons and in every balloon group there are 3 blue balloons. 9*3=27
ohhh yay we got the correct answer
i got 24$
on the last question i just asked can someone make sure i did that right please
At an amusement park, each premium ride costs $12 and each gold star ride is $8. Stan spends $96 on tickets and he gets 3 more premium rides than gold star rides. How much does he spend on gold star rides?
$24
??????
yes I am here
Ok lets set up our equation first
ok so we purchase $96 worth of tickets we buy x amount of gold tickets and x+3 premium tickets ok
now how would you set up our equation?
did i lose you?
no i just already figured out that i was right
lol
yes you are correct sorryyyyyy
I thought premium rides hahahahaahah
ok so you got it :) U R AWESOME
Let gsr be the number of gold start rides that Stan bought. Solve the following for gsr: 12 (gsr + 3) + 8 gsr = 96 gsr = 3 8*3 = $24
Miguel is making smoothies out of yogurt and juice to serve to his friends, and he needs to make 12 cups. The ratio of yogurt to juice is 2 cups to 1 cup. How much yogurt will he use?
ok so lets label juice as x and so for every cup of juice we have 2 cups of yogurt Yogurt=2x How would we set up our equation?
2 times 12 right but the only thing about that is that these are the choices i have for the answer 3,4,8,9
x+2x=12 3x=12 x=4 So he uses 4 glasses of juice Yogurt is 2x=2*4=8 So he will use 8 cups of yogurt
oh ok that makes more sense than what i tried doing lol
lol
Latonya bought flowers for her mother. She spent $45. Each tulip was $1 and each rose was $2. She bought 3 more tulips than roses. Let t be the number of tulips. Which algebraic sentence would help you figure out how many tulips Latonya bought?
A. t + 2(t + 3) = 45 B. t + 2(t – 3) = 45 C. 2t (t + 3) = 45 D. -3t + 2t = 45
Ok lets skip the algebraic sentence first and try to set up the equation
ohh they provided that answer
ok so you tell me.
one sec let me try to figure that out haha in my HEAD lol
ok there is something tricky here. Should I give you a hint
YES PLEASe
i think it would either be A or C is that correct at least?
ok t=tulips we have 3 more tulips than roses Now that is another way of saying that we have 3 less roses than tulips
Sorry thats incorrect :(
ok lets work through it together
ok we have t amount of tulips and how many roses do we hav
2?
well they cost $2 per rose
but how many roses do we have in comparison to tulips
if we have t tulips then how many roses do we have Do we have more roses than tulips Or less roses than tulip
She bought 3 more tulips than roses. meaning that we have more tulips than roses correct?
if we have t amount of tulips we have 3 less roses
$28 on roses and $17 on tulips right
A. t + 2(t + 3) = 45 B. t + 2(t – 3) = 45 C. 2t (t + 3) = 45 D. -3t + 2t = 45 i still think the answer is either a or c but do those make sense
Ok you got the correct answer so what was your equation
How did you get your answer?
i didnt write down any equation but since i am adding so many ts more than roses i did the t+3 obviously and i would assume t+3 at the beginning because its a dollar plus two one for the tulip and two for the rose so the equations just look like a or c could work for solving it am i right?
ok let me show what I did We have t tulips and t-3 roses
i added 3 together until i got to 42 and then added just the three tulips to get 45
Since we have 3 roses less than tulips
so we have t+2(t-3)=45 and since we have 17 tulips plug in t=17 and you will see you will get the correct answer
so our answer is B
this one was confusing We had t tulips and we didnt have more tulips than roses but we had 3 less roses than tulips Roses=t-3
A little late for the yogurt/juice problem. Let y and j be then number of cups of yogurt and juice, respectively, to make 12 cups of smoothies. Solve the following for y and j. The dimensions for the first equation is cups and the second equation is dimensionless, a pure ratio.\[\left\{y+j=12,\frac{y}{j}=2\right\}\]\[\{y=8 \text{ cups},j=4 \text{ cups}\} \]
oh ok so thats where i got confused lol i was assuming it was +3 but -3 makes more sense
lol it was a little tricky
thankss for everything LATER ;]
Bye :)
