Answer:
I think the answer is y = 3x - 10
Step-by-step explanation:
The slope of the line is the rate of change
The 4 1/2 gets converted to 9/2 and 4 3/4 becomes 19/4. You then multiply straight across and you shall get 21.38
For 4. (Apples to balloons) it is really simple. All you have to do is count the amount of balloons and apples and turn into a ratio, which is a basically a fraction. The answer for that would be 4:2
For the other 4, im not sure what the answer is as i cant really see it that well.
3 and 3 are pretty easy too. All you need to do is find a common factor. For the first number 3, 6 and 8 can both be divided by 2. The will turn it in 3/4, which is as simple as the number can get. The next one can also be divided by 2, which will turn it into 5/7. Once again, this is as simple as it can get.
Answers:
3. 3/4
3. 5/7
4. ? (couldn't see it)
4. 4:2
Following order of operations:
3^2 = 9
(10-2) = 8
Now you have :
9 + 8 x 5 -4
Multiplication is next:
9 + 40 -4
Now just add and subtract from left to right:
9 + 40 = 49
49-4 = 45
The answer is 45
