Question

Evaluate the expression for a=3 and b=10 70/b +5a -2b

Answer 1

2

Explanation:

evaluate from left to right, substituting the given values into the expression

=
`(70)/(10)` + (5 × 3) - (2 × 10)

= 7 + 15 - 20

= 22 - 20

= 2

Answer 2

Substitute the values of a and b to the expression:

`a=3,\ b=10\\\\(70)/(b)+5a-2b=(70)/(10)+(5)(3)-(2)(10)\\\\=7+15-20=22-20=\boxed2`
