Hi




Can you share a strategy for error analysis? Of multiplying.

Answers

Answer 1
Yes ! Because it’s that because it’s it
Answer 2
Not sure if this is right, but your teacher could give you a multiplication problem and she solves it. The twist: She makes an error within the work she did to solve it & therefore got the wrong answer. It’s now your turn to figure out where the error was and how to fix it to get the correct answer.

The ratio of Jenny’s trophies to Meredith’s trophies is 7:4. The difference between the numbers is 12. What are the numbers?

Answers

28 and 16 are the numbers

The two numbers would be 28 and 16 respectively.

What is Equation Modelling?

Equation modelling is the process of writing a mathematical verbal expression in the form of a mathematical expression for correct analysis, observations and results of the given problem.

We have the ratio of Jenny’s trophies to Meredith’s trophies is 7 : 4. The difference between the numbers is 12.

From the question, we can write -

7x - 4x = 12

3x = 12

x = 4

The numbers would be -

[a] = 7x = 28

[b] = 4x = 16

Therefore, the two numbers would be 28 and 16 respectively.

Answers

Answer:  21.5

Step-by-step explanation:

Answer:

21.50

Step-by-step explanation:

43 ÷ (7 − 3) × 2

According to order of operations you would do 7 - 3 first which gets you to 4.

43 ÷ 4 × 2

Now you would do 43 ÷ 4 which is 10.75 so next...

10.75 × 2

You should get an answer of 21.50

Tell whether the ratios form a proportion.
1 to 0.4 and 9 to 3.6

Answers

Answer:

no?  cause one is negative and the other is positive and I'm guessing they both have to be the same

Step-by-step explanation:

3  =  x

x         3

These are fractions btw

Cross multiply:

3 * 3 = x * x

Simplifying

3 * 3 = x * x

Multiply 3 * 3

9 = x * x

Multiply x * x

9 = x2

Solving

9 = x2

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '-1x2' to each side of the equation.

9 + -1x2 = x2 + -1x2

Combine like terms: x2 + -1x2 = 0

9 + -1x2 = 0

Add '-9' to each side of the equation.

9 + -9 + -1x2 = 0 + -9

Combine like terms: 9 + -9 = 0

0 + -1x2 = 0 + -9

-1x2 = 0 + -9

Combine like terms: 0 + -9 = -9

-1x2 = -9

Divide each side by '-1'.

x2 = 9

Simplifying

x2 = 9

Take the square root of each side:

x = {-3, 3}

The answer is 3=x I think
