Answer:
x=2
y=3
Step-by-step explanation:
y=−2x+7
y=5x−7
Set the two equations equal since they are both equal to y
−2x+7
=5x−7
Add 2x to each side
-2x+7+2x = 5x-7+2x
7 = 7x-7
Add 7 to each side
7+7 = 7x-7+7
14 =7x
Divide by 7
14/7 = 7x/7
2 =x
Now find 7
y = 5x-7
y = 5(2) -7
y = 10-7
y = 3
Answer:
NP = 43
LNO = 137
MNP = 137
Step-by-step explanation:
MNL is a vertical angle to PNO, therefore they are equal
MNL = PNO
MNL = 43 = PNO
MNL and LNO are supplementary angles. They add to 180 degrees
MNL + LNO = 180
43+LNO = 180
Subtract 180 from each side
43-43 +LNO = 180-43
LNO = 137
LNO and MNP are vertical angles. Vertical angles are equal
LNO = MNP
137=MNP
The mother is older than her daughter by
years
Step-by-step explanation:
Mother is m years old, and she is four times as old as her daughter.
we need to find how much older the mother is than her daughter
- Put the age of mother equal 4 times the age of daughter
- Find the age of daughter
- Subtract the age of daughter from the age of mother to find how much older the mother than her daughter
∵ The mother's age = m
∵ Her age is four times as old as her daughter
∴ m = 4 × daughter's age
- Divide both sides by 4
∴
= daughter's age
- Subtract the daughter's age from her mother's age
∵ The difference of their ages = m -
- Change 1 m to a fraction of denominator 4, then 1 m = 
∴ The difference between their ages =
-
= 
∴ The mother is older than her daughter by
years
The mother is older than her daughter by
years
