Answer:
13
Step-by-step explanation:
[tex]39 \div 3 = 13[/tex]
Answer:
k = 13
Step-by-step explanation:
k represents a number. You don't know what the number is.
3k = 39 means three times a number is 39. What is the number?
3k = 39
Divide both sides by 3.
k = 13
The number is 13.
Answer: k = 13

Divide and simplify
Idk what it is
Answer:
B it was b when I answered
Answer:
The answer is B. 5/1
Step-by-step explanation:
Convert them into improper fractions: it would become 65/6 divided by 13/6. After that do the process of dividing fractions: keep the first one the same, change the sign to multiplication and flip the second fraction to 6/13. After that, multiply the two numerators and denominators to get 390/78. This simplifies to the whole number 5, but in your case, 5/1.

Write equivalent fractions for
9/10
and
1/5
using the least common denominator.
Type the fractions, using a slash ( / ) to separate the numerator and denominator.
9/10=
1/5=
Answer: 9/10 stays the same and 1/5 turns into 2/10
Step-by-step explanation: The least common denominator is 10. 9/10 stays the same because the denominator is 10 in it. 1/5 turns into 2/10 because you have to multiply the numerator and denominator by 2 so 1/5 turns into 2/10.
9/10 stays the same and 1/5 turns into 2/10 for the given fractions.
What is the least common denominator method?The least common denominator is 10. 9/10 stays the same because the denominator is 10 in it. 1/5 turns into 2/10 because you have to multiply the numerator and denominator by 2 so 1/5 turns into 2/10.
List the multiples of both denominators until you discover the smallest multiple that both share to get the least common denominator. 28 must be the least common denominator for these two fractions since it is the first shared multiple of 4 and 7, respectively.
Hence, 9/10 stays the same, and 1/5 turns into 2/10 for the given fractions.

1/4(x+3)=4(x+3)
what is the solution? will give brainliest. please show work or explain!
Answer:
x=3
Step-by-step explanation:
You multiplie 1/4 to x+3 and 4 to x+3
1/4x + 3/4= 4x+12
You subtract 12 on both sides
1/4x -11 and 1/4= 4x
You then subtract 1/4 x on both sides
-11 and 1/4= 3 and 3/4x
Then divide 3 and 3/4 from both sides

A.) 150 + 100x + 50 = 350
B.) 100x + 150 = 50x + 350
C.) 150 + 350 = 50x + 100x
D.) 100 + 150x = 50 +350x

if x=8 then y=4. What is the value of x when y=8?
Answer:
x = 16
Step-by-step explanation:
You can create a proportion to solve this.
X over Y --> 8 over 4 (picture this in fraction form lol)
8 over 4 = x over 8
Cross-multiply
4x = 64
Divide both sides by 4
x = 16

8 over 13 multiplied by 7 over 13
8 over 13 added to 7 over 12
8 over 13 multiplied by 7 over 12
8 over 13 added to 7 over 13
Answer:
8 over 13 multiplied by 7 over 12
Step-by-step explanation:
The answer is 8 over 13 multiplied by 7 over 12 because the probability of choosing a blue marbel in the first trial was 8/13. This is because there are 13 marbles in all and 8 of them are blue. The second time, it was 7/12 because you had already picked up a marble and probably didn't put it back in the bag. You multiply 8/13 by 7/12 to find the overall probability of choosing two blue marbles in both trials.

3. Write the equations for both contestants.
3. Write the equations for both contestants.
Valerie:
Oscar:
1. Valerie weighed more at the beginning of the show.
2. Valerie losing weight faster.
3. The equations are as Valerie: W = 235 - 2.5t and Oscar: W = -2t + 247
What is the equation?The equation is defined as a mathematical statement that has a minimum of two terms containing variables or numbers that are equal.
1. Valerie weighed more at the beginning of the show, as her starting weight was 235 pounds, while Oscar's was 247 pounds.
2. Valerie's weight loss per week can be found by taking the derivative of her weight loss function:
W' = -2.5
So, Valerie is losing 2.5 pounds per week.
Oscar's weight loss per week can be calculated by finding the difference in his weight between weeks and dividing it by the number of weeks:
(247 - 243) / 2 = 2 pounds per week
So, Oscar is losing 2 pounds per week.
Therefore, Valerie lost weight faster.
3. The equations for Valerie and Oscar are:
Valerie: W = 235 - 2.5t
Oscar: His weight loss function as a line that passes through given points.
W = -2t + 247
Here W is his weight in pounds and t is the time in weeks.
