Question

A=-6 and b=5 when 2(-10a+5b)

​

Answer 1

190

Explanation:

Hello!

We can evaluate the expression by substituting the values of a and b.

Evaluate

• 2(-10a + 5b) ; a = -6, b = 5
• 2(-10(-6) + 5(5)) Multiply
• 2(60 + 25) Simplify
• 2(85) Expand
• 190

The evaluated expression is 190.

Answer 2

`\sf \: 2( - 10a + 5b) = 170`

Explanation:

Given expression,

→ 2(-10a + 5b)

Additional information,

→ a = -6

→ b = 5

Now the value of expression is,

→ 2(-10a + 5b)

→ 2(-10a) + 2(5b)

→ 2(-10 × -6) + 2(5 × 5)

→ 2(60) + 2(25)

→ 120 + 50

→ 170

Therefore, the answer is 170.
