(-5, 2 ) means x = -5 and y = 2
so answer is <span>point D</span>
3A+2B=20
2A+B=13 ➡×(-2)➡-4A-2B=-26
3A+2B-4A-2B=20-26
-A=-6 ➡A=6
2(6)+B=13➡B=1
Two -2x and 2x cancel out since there opposites
As well as y
Then your answer should be 0=-1
Answer:
The total cost of the bike is $180.
Step-by-step explanation:
Given that Juanita has saved 35% of the money for a bike.
Let the total cost of the bike = x
As she has saved $63 dollars which represents the 35% of the money for a bike.
In other words, 35% of the total cost is $63 dollars.
As the total cost = x
Thus,
35% of x = 63

Multiply both sides by 20

simplify

Divide both sides by 7

Simplify
$
Thus, the total cost of the bike is $180.
