You isolate the variable (a)
-3a = -18
/-3
a = 6
11=5+5+1
11/5=5/5+5/5+1/5=1+1+1/5=2 and 1/5
Answer: B
Because 3x4=12 and 5x4=20
Answer:
- x^2+y
- 3(n-7)
- 37x-9.85
Step-by-step explanation:
1. If x represents a number, then x^2 represents its square. If y represents a second number, then the sum of that square and the second number is ...
x^2 + y
__
2. The difference of a number (n) and 7 is (n-7). Three times that difference is ...
3(n - 7)
__
3. If x represents a number, then the product of 37 and a number is 37x. 9.85 less than that is ...
37x - 9.85
