Answer:
3(n+5)=-30
Step-by-step explanation:
Three times the sum of a number and 5 is - 30
Vocabulary:
times = multiplication, represented with *
sum = addition, represented by +
unknown number = n
Three * the sum of a number and 5
The sum of a number and 5 is the same as saying n + 5
So we are multiplying 3 by n + 5
Because n is an unknown variable we have to separate the sum of n and 5 from being multiplied by 3 with parenthesis. We do this because if we want to multiply 3 by the sum of n and 5. If we put 3 * n + 5 we are only multiplying the unknown variable by 3 not including the 5 that is added to it.
So we get 3( n + 5 ) is -30
3(n+5)=-30 is the answer.

Answer:
Step-by-step explanation:
-The total portion fed to the dog is 7/10 cup
- Canned-3/10
- Dry=7/10-3/10=4/10
-One week has 7 days. we multiply the dry portion per day by the number of days in a week.
Hence, Erin feed her dog 2 4/5 0r 2.8 cups of dry food
