Alex bought a total of 65 more raffle tickets than Juan. Together they bought 343
raffle tickets. How many raffle tickets did each download?
Answer:
Juan bought 139 tickets and Alex bought 204.
Step-by-step explanation:
Suppose Juan bought a total of [tex]x[/tex] tickets. Then Alex bought 65 more, which is [tex]x+65[/tex]. The sum of both totals is [tex](x)+(x+65) = 2x + 65[/tex], but we are also given that this is equal to 343. So [tex]2x+65 = 343[/tex], and as such [tex]2x = 343-65=278[/tex], so [tex]x = \frac{278}{2} = 139[/tex]. Therefore, Juan bought 139 tickets and Alex bought 65 more, which is 204.

what is 9/32 + 7/8 plz help
Answer:
1 5/32
Step-by-step explanation:
First, find common denominators. What you do to the denominator, you must do to the numerator.
First, multiply 4 to both the numerator and denominator of the second fraction:
(7/8)(4/4) = (7 * 4)/(8 * 4) = 28/32
Next, add across:
9/32 + 28/32 = 37/32
Simplify. Turn the improper fraction into a mixed fraction:
37/32 = (32 + 5)/32 = 1 5/32
1 5/32 is your answer.
~
Answer:
37 /32
Step-by-step explanation:
Find the least common denominator or LCM of the two denominators:
LCM of 8 and 32 is 32
For the 1st fraction, since 8 × 4 = 32,
7 /8 = 7 × 4
8 × 4 = 28 /32
Likewise, for the 2nd fraction, since 32 × 1 = 32,
9 /32 = 9 × 1
32 × 1 = 9 /32
Add the two fractions:
28 /32 + 9/32 = 28 + 9 /32 = 37 /32
So, 7/8 + 9/32 = 37/32
In mixed form: 1 5 /32

Solve 3x - 5 = 16
Write your solution starting with x= .
Answer:
x =7
Step-by-step explanation:
To solve this, you must get x by itself.
3x-5 = 16 1. Add 5 on both sides
3x = 21 2. Divide by 3 on both sides
x = 7

Peter is renting two kinds of rafts for a vacation company. One type seats 3
people and the other seats 5 people. If 53 people are using the vacation
company and he rents 13 rafts, how many of each type of raft does he rent?
Answer:
Peter rents 6 of the rafts seating 3 people, and 7 of the rafts seating 5 people.
Step-by-step explanation:
Let [tex]x[/tex] denote the number of rafts seating 3 people and [tex]y[/tex] the number of rafts seating 5 people. The total number of rafts is 13, so [tex]x+y=13[/tex]. We can also assume that every raft is filled to the brim (it isn't stated explicitly though, but it's probably the intention of the question maker), so [tex]3x+5y=53[/tex].
It's always a good idea to put these equations under each other:
[tex]\left \{ {{x+y = 13} \atop {3x+5y=53}} \right.[/tex]
We can subtract the first equation three times from the second one to obtain [tex](3x+5y)-3(x+y) = 53 - 3(13)\\3x-3x + 5y - 3y = 53 - 39\\2y = 14\\y=\frac{14}{2} = 7[/tex]
Now, substitute this found value for [tex]y[/tex] into [tex]x+y = 13[/tex] and we see that [tex]x=6[/tex]. We are now done: Peter rents 6 of the rafts seating 3 people, and 7 of the rafts seating 5 people.
