Since she runs 6
miles each day and there 7 days per week, you will have to multiply 6 times 7.
But since you have to use distributive properties, multiply like this (6)(7)
6 is equal to 
Now turn 7 into a fraction, so its 
Now multipy (6)()
Multiply the numerators, so its 7 * 13 which gives you 91 and multiply the denominators so its 1 * 2 which gives you 2.
Put that back into a fraction as 
Divde it to change it to a mixed number and the answer is 45
Answer:
7 18-inch wreaths
26 22-inch wreaths
Step-by-step explanation:
Let's say the number of 18-inch wreaths is x and the number of 22-inch wreaths is y.
We know that the number of 22-inch wreaths sold was 5 more than 3 times the number of 18-inch wreaths sold. We can write this into the expression as:
y = 5 + 3x
We also know that each 18-inch wreath was $20 and each 22-inch wreath was $25. The total cost was $790, so:
20x + 25y = 790
Now, let's substitute 5 + 3x in for y in the second equation:
20x + 25y = 790
20x + 25(5 + 3x) = 790
20x + 125 + 75x = 790
95x + 125 = 790
95x = 665
x = 7
Plug this value into y = 5 + 3x to find y:
y = 5 + 3x
y = 5 + 3 * 7 = 5 + 21 = 26
So, 7 18-inch wreaths were sold and 26 22-inch wreaths were sold.
Answer:
The expression for the other number is (n-1)
Step-by-step explanation:
we know that
The difference between two consecutive number is equal to 1
Let
x ----> the smaller of two consecutive number
n ----> the larger of two consecutive numbers
we have that
Solve for x
therefore
The expression for the other number is (n-1)
Answer:
1a. first 7×9=63 Then substracting 16 we get 47 and 2-47= -45
