Marco needs to save a minimum of $420 more to buy a smartphone.
<u>Explanation:</u>
Cost of a smartphone = $495
Savings = $75
Least amount of money, m that needs to be saved = ?
Additional savings, m = Total - initial savings
m = $495 - $75
m = $420
The inequality equation would be 75 + m ≥ 495
Therefore, Marco needs to save a minimum of $420 more to buy a smartphone.
Answer:
47
Step-by-step explanation:
According to the number system 7 lines and 12 dots, a line is 5 and a dot is 1

There are a lot more problems but here are a couple to help you for now.
In the given figure three angles are marked x°, 56° and 146 °
When two lines intersect they form two pairs of opposite angles. Vertical angles are always congruent, which means that they are equal.
In the figure angles x ,56 and 146 are formed on two opposite sides of the straight lines are so are vertically opposite angles and hence they are equal.
We can write this as x+56=146.
The first option is the right answer.
<u><em>Answer:</em></u>
f (5) = 7.5
<u><em>Explanation:</em></u>
<u>The function given is:</u>
f (n+1) = -0.5 f (n)
<u>We are also given that:</u>
first term is 120
<u>This means that:</u>
f (1) = 120
<u>We will get the other terms by substitution as follows:</u>
f (2) = -0.5 f (1) = -0.5(120) = -60
f (3) = -0.5 f(2) = -0.5(60) = 30
f (4) = -0.5 f(3) = -0.5(30) = -15
f (5) = -0.5 f(4) = -0.5(-15) = 7.5
Therefore, f (5) = 7.5
Hope this helps :)
