Question

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

Answer 1

Substitute the values of a and b to the expression:

$a=3,\ b=10\\\\\dfrac{70}{b}+5a-2b=\dfrac{70}{10}+(5)(3)-(2)(10)\\\\=7+15-20=22-20=\boxed2$

Answer 2

Answer:

2

Step-by-step explanation:

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

= $\frac{70}{10}$ + (5 × 3) - (2 × 10)

= 7 + 15 - 20

= 22 - 20

= 2
