It would be -6. -4-6 is -10
The variable in this equation is b, therefore we have to calculate the value of b.
-38=2b+25-(-7b)
-38=2b+25+7b
2b+7b=-38-25
9b=-63
b=-63/9
b=-7
Answer: the value of the variable is b=-7
We can check it out this answer:
-38=2b+25-(-7b)
-38=2(-7)+25-(-7(-7))
-38=-14+25-49
-38=-38
Step-by-step explanation:
c
Answer:
10(2+3)
Step-by-step explanation:
We are given that
Ice=20 lb
Cup=30
We have to find the expression which shows the greatest common factor using distributive property of 20 and 30.
We know that distributive property of integers a,b and c




Hence, the highest common factor of 20 and 30=10
Expression:10(2+3)
