Explain when you know you need to rename a mixed Number to subtract.

Answers

Answer 1

Answer: You know that you need to rename a mixed Number to subtract when the numbers involved have different denominators. In such a case, the lowest common multiple (LCM) of the denominators must be calculated and subsequently used to adequately rename the mixed numbers before subtraction can be done.

What is the mean of the set of numbers? –12, –4, 3, 7, 11

Answers

To find the mean, we need to add up all of the numbers, and then divide by the number of numbers...

–12, –4, 3, 7, 11 In the data set, there are 5 numbers...

(-12+(-4)+3+7+11)=5/5=1

Answer=1

Hi there! To find the mean we add up all of the data and then divide by how many numbers there are. In this case we have the numbers of -12, -4, 3, 7, and 11. -12+-4+3+7+11=5. Now, we divide by how many numbers there are. In this case we have 5 numbers of data. 5 divided by 5 equals 1. Therefore, the mean of the set of numbers is 1.

please I need help

Answers

Answer:

The answer is y = -2.

Step-by-step explanation:

To start, you need to cross multiply to solve.

3/y = 6/(y -2)

y*6 = 3*(y -2)

6y = 3y - 6

3y = -6

y = -2

Find three different ratios that are equivalent to 7:3

Answers

Answer:

14 : 6, 21 : 9 and 28 : 12

Step-by-step explanation:

Given ratio,

7 : 3

Since, when we multiply both numerator and denominator by a same number then we get an equivalent fraction,

That is,

$(7)/(3)=(7* 2)/(3* 2)=(14)/(6)$

$(7)/(3)=(7* 3)/(3* 3)=(21)/(9)$

$(7)/(3)=(7* 4)/(3* 4)=(28)/(12)$

Hence, the different ratios that are equivalent to 7:3 are,

14 : 6, 21 : 9 and 28 : 12

Answer:

14:6

21:9

28:12

Step-by-step explanation:

Given the initial ratio of 7:3, you can find equivalent ratios by multiplying the two numbers by the same factor:

7 x 2 = 14

3 x 2 = 6

14:6

7 x 3 = 21

3 x 3 = 9

21:9

7 x 4 = 28

3 x 4 = 12

28:12
