Answer:
5 carrots are left over.
Step-by-step explanation:
6 times 7 equals 42. 47 minus 42 is 5.
Put the values where the variables are, then do the arithmetic.
8 - 8/2 +7² = 8 - 4 + 49 = 53
Answer:
Option C, (6, 8.4)
Step-by-step explanation:
It would be option C because all of the other ones, both the y and x value is almost the same. (2, 2.1) (4, 3.8) and (9, 9) are all really close in y and x values. While (6, 8.4) has a y value that is over 2 more than x.
Answer: Option C, (6, 8.4)
It is easier to do one question at a time
Answer:
Step-by-step explanation:
Let the muffin number = x
Let the pie number = y
x + y = 30 Solve for y. Subtract x from both sides
y = 30 - x
Now calculate the cost
2.5 x + 9 = 4.5 y Substitute for y on the right.
2.5x +9 = 4.5 (30 - x) Remove the brackets.
2.5x + 9 = 135 - 4.5 x Add 4.5 x to both sides
2.5x + 4.5x + 9 = 135 Combine the left.
7x + 9 = 135 Subtract 9 from both sides
7x = 135 - 9
7x = 126 Divide by 7
7x/7 = 126 / 7
x = 18
There were 18 muffins
x + y = 30
18 + y = 30 Subtract 18 from both sides
y = 12
