Hello,
When you are looking for a ratio, it is simply a fraction.
In the numerator, we will put the amount of the increase which is 10.4 - 7.80 = 2.6.
In the denominator, we will put the original price of $7.80.
This gives us the ration of 2.6/7.8 or just 0.33 if we divide.
We can say there was a 33% increase (or one-third).
I hope this helps, Good luck!

(X - 3)+(2x + 8)+(2x) = 180
5x + 5 = 180
5x = 175
X = 35
The answer is A which is 125
Answer:
yes
Step-by-step explanation:
2+2+2=6
3+3=6
First question:
When you bisect an angle, you create two new equal angles, both measuring half of the original angle. So, if the original angle was 52°, the two angles will be 52/2=26 degrees each.
Note: the picture is not very clear, and I'm not sure the original angle is 52°. It it's not, just divide by 2 whatever measure the angle is.
Second question:
Focus on triangles RQP and RSP:
- They are both right, because Q and S are right angles
- We are given QP=SP
- They share the side RP
So, they are congruent. This implies that angle SRP is 50° as well, and then
QRS = QRP+SRP = 50°+50°=100°
