Answer:
The inequality can be represented as:
where represents the number of weeks in which Maria will be able to buy a phone for least $200.
On solving it we get :
Step-by-step explanation:
Given:
Maria wants to buy a phone for at least $200.
She has savings of $125.
She plans to save $10 every week.
To write an inequality for the situation.
Solution:
Let the number of weeks in which Maria will be able to buy a phone be =
If she saves $10 each week.
Then, in weeks she will save in dollars =
She already has savings = $125
So her total savings in weeks in dollars will be =
She wants to buy a phone for at least $200.
Thus, the inequality can be represented as:
Solving for
Subtracting both sides by 125.
Dividing both sides by 10.
Thus Maria needs at least 7.5 weeks to be able to buy a phone for atleast $200.
Check the picture below.
as you recall from the previous exercise, x = 74°, now, using the "inscribed angle theorem" as you saw already, the green intercepted arc is 160°, so y = 160° - 74°.
as far as ∡z, well, we can just use the "inscribed quadrilateral conjecture".
