Answer:
x = 127°
Step-by-step explanation:
in each triangle, the value of each exterior angle is equal to the sum of its two non-adjacent interior angles..
47° + 80° = 127°
or
the third angle in the triangle:
180° - (47° + 80°) = 53°
exterior angle:
180° - 53° = 127°
Answer:
With $30, Peter can afford 5 hours
Step-by-step explanation:
Given
Insurance Charge = $7.5
Charges = $4.5 per hour
Required
Determine the number of hours $30 can afford
First, we need to determine the equation.
<em>Total Charges = Charges per hour + Insurance Charge</em>
Substitute values for Charges per hour and Insurance Charge
Total Charges = 4.5 per hour + 7.5
Let the number of hours be n;
So,
Total Charges = 4.5n + 7.5
To calculate Peter's; substitute 30 for total charges

Subtract 7.5 from both sides


Divide both sides by 4.5


Hence;
<em>With $30, Peter can afford 5 hours</em>
We need to get rid of expression parentheses.
If there is a negative sign in front of it,
each term within the expression changes sign.
Otherwise, the expression remains unchanged.
Numerical 'like' terms will be added. There is only one group of like terms
the answer is: ab-4a-5
