Answer:
11.20
Step-by-step explanation:
Multiply both equations by 100:
19.99=1999
8.79=879
1999-879=1120
Divide by 100:
1120/100=11.20 saved ................
Answer: 11/15
Step-by-step explanation:
Answer:
-3/12
Step-by-step explanation:
Let's solve for x first,
3x + 5y - 5y = 1 - 5y
3x/3 = 1/3 - 5y/3
x = 1/3 - 5/3y
Let's now plug that into the other equation,
7(1/3 - 5/3y) + 4y = -13
7/3 - 35/3y + 4y = -13
7/3 - 7 2/3y - 7/3 = -13 - 7/3
- 7 2/3y (-3/23) = -15 1/3 (-3/23)
y = 2
The answer is 2
Answer:
The reflexive property of congruence allow us to say that RST = RST .
Option (C) is correct .
Step-by-step explanation:
Definition of Reflexive Property of congurence
The meaning of Congruence is figure has the same size and shape. If you were comparing something to itself, then it definitely have the same size and shape this is called Reflexive Property of congurence .
By using Reflexive property of congurence .
RST = RST
Therefore reflexive property of congruence allow us to say that RST = RST .
Option (C) is correct .
