Answer :
A= -1
Explanation:
Given:
cat carrier : 39.99
cat tower: 19.99
1st discount : 5%
2nd discount: 15% - cat tower
39.99 * 5% = 1.99
39.99 - 1.99 = 38
19.99 * (5% + 15%) = 19.99 * 20% = 3.99
19.99 - 3.99 = 16
38 + 16 = 54

Answer:
- angle SVR = 30°
- angle PVR = 90°
- angle SVQ = 60°
- angle SVP = 120°
- angle RVQ = 30°
Step-by-step explanation:
As with finding distances on a number line, the easiest way is to subtract the smaller coordinate from the larger. Here, the "number line" is the arc at the edge of the protractor. The corresponding coordinates are ...
S: 40°
R: 70°
Q: 100°
P: 160°
The measure of an angle with its vertex at V will be the difference between the "coordinates" of the endpoints of the arc it intercepts. That is ...
m∠SVR = "R" - "S" = 70° -40° = 30°
The other angles are found the same way:
m∠PVR = 160° -70° = 90°
m∠SVQ = 100° -40° = 60°
m∠SVP = 160° -40° = 120°
m∠RVQ = 100° -70° = 30°
The easiest way to do this is to break it down and translate it before solving. Start with twice a number, if you use n to represent eh number, you will have 2n. Then, add the 'less than' part. 'Five less than' means that five is being subtracted from the next part, which is 2n. Now you have 2n - 5. The last translation is simple, 'equal to 57' will complete the equation as 2n - 5 = 57.
If you want to solve the equation, use the Order of Operations.
2n - 5 = 57 Add 5 to both sides
2n = 62 Divide both sides by 2
n = 31
