Step-by-step explanation:
HI Sofia!
So this is how you find the answer.
Amount of money pietro has=$75
Amount of money he spent on shoes=3/5 of 75
=3/5*75= 45
Thus, Pietro spent $45 on shoes.
-2 1/2 - (-1 3/4)
When subtracting a negative vile the equation becomes addition:
-2 1/2 + 1 3/4 = -3/4
Answer: -3/4
Check the picture below.
so, bearing in mind that vertical angles are equal, thus ∡AED = ∡BEC, and we know that ∡BEC = 52 = ∡AED, so those two angles added up are 104°.
now, a circle has a total of 360°, if we take away those 104° from the red angles, what's leftover is just 256°, well, the green angles there are also vertical angles and thus twins, so each one will take half of 256°.
∡BEA = 128° = ∡CED.
The value (y2) of r = 1/2.
This question relates to equation of a straight line but we are looking for the slope in this case.
<h3>Slope</h3>
This is the ratio to which we measure the change along the y-axis to the change along the x-axis. The formula is given as

Data given;
- x1 = 3
- x2 = -3
- y1 = 5
- y2 = r
- m = 34 or 3/4
Substitute the values into the equation and solve for the unknown
NB; we are assuming that the slope here is 34 and not 3/4.

cross multiply both sides and make r the subject of formula

the value of r = -199.
This is not mathematically obtainable and we would use 3/4 as the value of slope

The most logical value of r = 1/2
