Answer:
angles opposite each other are the same
this is called corresponding angles
Step-by-step explanation:
Answer:its the second fourth and fifth
Step-by-step explanation: just did it on edge
1. B. The retail price would be the purchase price plus the markup.
So p+.40p = 1.40 p = 1.4 p. (p is really 1 p)
C. You would multiply: 1.4(56) = $78,40
D. You could multiply .4p = .4(56). OR subtract: 78.40-56 = $22.40
2. Done
3. 10(.35) = $3.50 —— 10+3.50=$13.50
4. 40(.25) = $10 ———- 40+10=$50
5 Done
6. $30.50/30% markdown 30.50(.30) = $9.15; 30.50-9.15= $21.35
7. $105/75% markdown 105(.75) = 78.75; 105-78.75= $26.25
8. $325/15% markdown 325(.15) = 48.75; 325-48.75= $276.25
9. C/40%markup Total retail:.40c + c = 1.40C
Answer: (5,2)
Step-by-step explanation:
Given equations:
Divide 2 on both sides of equation (1) and 4 on the both sides of equation (2), we get
Adding equation (3) and (4), we get
Substitute x=5 in equation (4), we get
Hence, the solution of the both equations is (5,2).
