Hello.

<u><em>When dividing fractions, you never actually divide. You actually flip the second fraction, then multiply.</em></u>

<u><em /></u>

<u><em>So, to convert this into a multiplication problem, we flip the second fraction, which is 4/7, then replace the division sign with a multiplication sign.</em></u>

<u><em /></u>

<u><em>The problem is now 3/11 x 7/4. None of the fractions can be simplified, so we multiply. Multiply across the top and bottom. (3 * 7 = 21) - (11 * 4 = 44)</em></u>

<u><em /></u>

<u><em>We end up with 21/44. It cannot be simplified, so this is our final answer.</em></u>

<u><em /></u>

<u><em>Hope this was helpful!</em></u>

Elimination/subtraction
denpristay [2]

Answer:

x = 0, y = 7

Step-by-step explanation:

Solving a system of equations using substitution requires one side to be equal to a variable present in the equation, in this case x or y. We should simplify the equation using elimination before substituting to reduce the chance of error.

In order to use the elimination method, you have to create variables that have the same coefficient—then you can eliminate them. These equations arew already aligned for us.

                  3x - 10y=-70

             -<u>   4x +9y = 63</u>

                  -x + y = 7

Now, for substitution, the equation must be set to a variable.

                  -x + y = 7

                  y = x + 7

Next, plug the equation in where applicable in another equation.

                  4x +9(x + 7) = 63

                  4x + 9x + 63 = 63

                  13x = 0

                  x = 0

The final step of substitution is to plug the known variable into an equation to find the other variable.

                  3(0) - 10y=-70

                  0 - 10y = -70

                  10y = 70

                  y = 7

I guarantee you this answer is correct, I worked it out using other methods and graphing prior to submitting this answer.

I want to just get in with life.
Ahat [919]

Answer:

The equation would be y = -2x + 1

Step-by-step explanation:

All you have to do is put it in the form y = mx + b where m is the slope and b is the y-intercept (for example, the equation y= 2x + 1 has a slope of 2 and a y-intercept of 1.)

Since you have slope, or m, = -2 and the y-intercept, or b, = 1, the equation would be y = -2x + 1

7. Explain the difference between whole numbers and counting numbers.<br>(2 marks)<br>Your answer​
Burka [1]

Counting numbers is like the numbers 1,2,3,4,5 and so on they were numbers you were probably taught to count to like to count through 1-10 or whatever. Counting numbers mean to count since they do have the word counting in them.

Whole number just means a number with no fraction or intger also 1 - infinity
