The answer is 59.99 because if you divide 180 by 21 you will get 8.57..... Then you need to multiply 8.57..... by 7 to get 59.99
5x+3÷4=7
5x+.75=7
-.75 -.75
5x = 6.25

Answer:
Mean for Labradors: 65
Step-by-step explanation:
This is how to find the M.A.D.
Step 1. Find the mean. To do that, you add all the numbers and divide that number by how many numbers you have which is 10. All the numbers together is 650. That divided by 10, is 65. That is your mean.
Step 2. Once you have that, subtract the mean from all 10 numbers.
Step 3. Find the mean of the 10 numbers which you have subtracted 65 (the mean) from. If the number you subtracted is a negative, make it a positive.
