Answer:
f(w) = 120 + 5(30-h)
Step-by-step explanation:
It is given that, Andrew gets paid $4 for first 30 hours of the week
So,
For first 30 hours, his wage will be:
4(30) = $120
Now, let w denote wages and h denote total number or hours he works in the week
So he will be paid $5 for h-30 hours
So the function will be
f(w) = 120 + 5(30-h)
Where $120 is the fixed income for first 30 hours and the second term is the wage of hours more than 30 at the rate of $5 per hour..
You have 135 blueberries, you share them equally among 9 friends. How many blueberries does each person get?
Answer:
To decide whether to add or subtract, determine if the values of the coefficients are the same or opposites:
. If the values are the same, subtract the equations.
• If the values are opposites or additive inverses, add the equations.
Step-by-step explanation:
Given
Required
How to solve
Options (1) and (2) are incorrect because none of the options eliminate x or y.
For option (3),
- Check for the coefficients of x and y
- If they are the same (sign and value), then subtract; otherwise add
For instance:
Rewrite the second equation
The coefficient of y are the same, so we subtract;
<em>See that y has been eliminated</em>
Answer:
x =21
Step-by-step explanation:
So we know that:
And that the two angles are vertical angles.
Since they are vertical angles, their measurements are equivalent. Thus, to find x, set the equations equal to each other:
Now, solve for x. Add 30 to both sides. The left side cancels:
Now, subtract 2x from both sides. The right cancels:
Thus, the value of x is 21.
