Answer: -10x+6.5
Step-by-step explanation:
Answer:
1
Step-by-step explanation:
1. Convert the mixed number to an improper fraction to match the rest of the problem (this just makes it easier for now, the answer will still be a mixed number)
-1
becomes 
2. Re-write the new equation. When there is a "+" in front of a set of parentheses the expression doesn't change aside from removing the plus signs.
The new equation becomes

3. Calculate. Just work out the new expression.
The answer is 
4. Convert to a simplified mixed decimal.
27 goes into 20 once with seven left over, making the answer 1
Answer:
246.
Step-by-step explanation:
Let the number be 2xy, then
2 + x + y = 2y and y must be even because the whole number is even.
y = 2 + x .
Now x must be even because y is even.
The only 2 numbers which fit are x = 4 and y = 6 so the number is 246.
Checking: 2+4+6 = 12 and 12 = 2*6.
Answer:
g(-5) = -6
Step-by-step explanation:
We need to find value of g(-5)
Looking at the graph in figure when g = -5, the value on the graph is -6 as it is highlighted with blue point.
because we have x = -5 so, we will look at graph that passes through x and y when x= -5, so we get y=-6
So, g(-5) = -6
