For question 9 the answer will be in the photo
There is 1 orange for every 3 apples. It can be expressed at 1:3 oranges to apples.
In order to find this, first count the number of each. We have 2 oranges and 6 apples. Since both have factors of 2, divide both numbers by two. This will give you the answer above.
Check the picture below.
make sure your calculator is in Degree mode.
Its 1/10 because 3 goes into 3 1 time and 3 goes into 30, 10 times
To solve this system, we can use substitution.
x + 6y = 61
x = 61 - 6y
Now we substitute into the other equation.
4 (61 - 6y) - 5y = -17
244 - 24y - 5y = -17
244 -29y = -17
29y = 261
y = 9
Now we find x.
x + 6 (9) = 61
x + 54 = 61
x = 7
That means the solution to this system is (7, 9)
