To evaluate the expression when a = 3 and b = 10, we substitute the values of a and b into the expression:
Start fraction seventy over b end fraction plus 5a minus 2b
= 70/10 + 5(3) - 2(10)
= 7 + 15 - 20
= 22
Therefore, the expression evaluates to 22 when a = 3 and b = 10.
To evaluate the expression, we substitute the given values of a and b into the expression and perform the calculations.
Given: a = 3 and b = 10
The expression is: (70/b) + 5a - 2b
Substituting the values, we have: (70/10) + 5(3) - 2(10)
Simplifying, we get: 7 + 15 - 20
Further simplifying, we have: 22 - 20
Finally, performing the subtraction, we find that the expression evaluates to: 2.
So, the correct answer is 2.
To evaluate the expression when a = 3 and b = 10, we substitute the given values into the expression and simplify:
Start fraction seventy over b end fraction plus 5a minus 2b
Substituting a = 3 and b = 10:
Start fraction seventy over 10 end fraction plus 5(3) minus 2(10)
Now, we simplify each part separately:
Start fraction seventy over 10 end fraction simplifies to 7.
5(3) simplifies to 15.
2(10) simplifies to 20.
Adding these three parts together, we get:
7 + 15 - 20 = 2
Therefore, the value of the expression when a = 3 and b = 10 is 2.
