The answer is 3x+15
You multiply the x and 5 by 3 to get 3x and 15
Alex and Case are starting their own businesses. Alex has $52 from pre-orders and plans on selling the mittens he made for $4 each pair. Case has $35 from pre-orders and plans on selling the mittens he made $5 each pair. Which equation could you use to determine when Alex and Case will have the same amount of money?
Answer:
Equation could you use to determine when Alex and Case will have the same amount of money is [tex]52+4x=35+5x[/tex]
Step-by-step explanation:
Let x be the pairs of mittens when Alex and Case will have the same amount of money
Alex has amount before orders = $52
He will sell 1 pair of mittens = 4
He will sell x pair of mittens = 4x
So, Alex's total amount = 52+4x
Case has amount before orders = $35
He will sell 1 pair of mittens = 5
He will sell x pair of mittens = 5x
So, Case's total amount = 35+5x
ATQ
52+4x=35+5x
52-35=x
17=x
Hence the pairs of mittens when Alex and Case will have the same amount of money is 17 and equation could you use to determine when Alex and Case will have the same amount of money is [tex]52+4x=35+5x[/tex]

the answer
7, 10, 11, 12, 13, 14, 17 are the 7 numbers that have a range of 10 and a mean of 12.
What is Statistics?Statistics is the discipline that concerns the collection, organization, analysis, interpretation, and presentation of data.
The range of a list of numbers is the difference between the largest and smallest values of that list of numbers.
The mean is the sum of the observations to the total number of observations.
The seven numbers are 7, 10, 11, 12, 13, 14, 17
Range =17-7=10
Mean=7+10+11+12+13+14+17/7
=84/7
=12
Hence, 7, 10, 11, 12, 13, 14, 17 are the 7 numbers that have a range of 10 and a mean of 12.

3x+8=13x-8x. Also it’s asking me to check can you send a check too thanks
Answer:
x = 4 CAN I HAVE BRAINEST PLZ
Step-by-step explanation:
3x + 8 = 13x - 8x (collect like terms)
3x + 8 = 5x (subtract 3x on both sides)
8 = 2x (divide by 2 on both sides)
4 = x

B. (4, 8, 12) D. (12, 6, 8)
Answer: C. (8, 16, 4)
Step-by-step explanation:
Given the following:
Let:
Trucks = T ; Cars = C ; SUVs = S
T =0.5(C + S) - 2 - - - (1)
C = 2T - - - (2)
T + C + S = 28 - - - (3)
T = 0.5(2T + S) - 2
T = T + 0.5S - 2
0 = 0.5S - 2
0.5S = 2
S = 2/0.5
S = 4
From T + C + S = 28
C = 2 T ; S = 4
T + 2T + 4 = 28
3T = 28 - 4
3T = 24
T = 24/3
T = 8
From T + C + S = 28
8 + C + 4 = 28
12 + C = 28
C = 28 - 12
C = 16
Hence, (T, C, S) = (8, 16, 4)

What is the value of k
Answer:
k = 5
Step-by-step explanation:
3x + k
im going to replace the x with the numbers that go there
3 x 1 + k = 8
3 x 1 = 3
8 - 3 = 5
k = 5
3 x 3 + k = 14
3 x 3 = 9
14 - 9 = 5
k = 5
3 x 5 + k = 20
3 x 5 = 15
20 - 15 = 5
k = 5

Step-by-step explanation:
In Akutan, Alaska, men are 77% of the population. It is also known 11.3% of
Akutan males smoke cigars while 2.1% of Akutan females smoke cigars. One
member of the population is selected at random for a survey involving cell
phone carriers.
Find the probability that the selected subject is not male.
Answer: 0.23
Step-by-step explanation:
Given that:
Percentage population of males = 77% = 0.77
Hence,
Percentage that aren't male = ( 1 - 0.77) = 0.23
P(males) = 0.77
Hence,
P(non-males) = 1 - 0.77 = 0.23

If "a" varies directly as "b" and inversely as "c". If a=16 when b=12 and c=6, find "a" when b=28 and c=4. *
Answer:
When b = 28 and c = 4, then a = 56
Step-by-step explanation:
We need to write the equation first
This is an example of a combined variation
if a varies directly as b and inversely as c;
then a = bk/c
where k is the constant of proportionality
We find k first;
16 = (12 * k)/6
k = (6 * 16)/12 = 8
We now want to find a
a = kb/c
a = (8 * 28)/4 = 7 * 8 = 56

33rd term 189.6, 172.3, 155
Answer:
[tex]a_{33}[/tex] = - 364
Step-by-step explanation:
There is a common difference between consecutive terms. that is
d = 172.3 - 189.6 = 155 - 172.3 = - 17.3
This indicates the sequence is arithmetic with n th term
[tex]a_{n}[/tex] = a₁ + (n - 1)d
where a₁ is the first term and d the common difference
Here a₁ = 189.6 and d = - 17.3 , thus
[tex]a_{33}[/tex] = 189.6 + (32 × - 17.3) = 189.6 - 553.6 = - 364
