Jennifer’s new bike cost $180. Her parents paid 40% of the cost and Jenifer paid the rest. How much did JENNIFER pay?
Explanations needed! I want to learn how to solve this problem.
Giving out brainliest to the most well explained answer and giving a “thanks” to all respondents
Answers
Answer:
Step-by-step explanation:
The new bike costs 180 dollars
Parents paid 40%
what is a percentage? per cent= divide by 100
parents paid 180 *40/100=180*0.4=72 dollars
Jennifer has to pay the rest
180-72=108
Answer:
$108
Step-by-step explanation:
You want to start by finding 40% of 180. When something says "of", you multiply! To make 40% in the correct format, move the decimal over to the right by two spaces, which leaves you with .40. As I said "of" means multiply, so you do .40 x 180, which = $72. This is the amount her parents paid, so you much subtract this from the total amount to find out what Jennifer paid. You do 180-72=$108. Jennifer paid $108!

Answer:
48,400 yd²
Step-by-step explanation:
(220+180)/2*260=52000
1/2(180)(60)=5400
So the total area is 52000+5400=57400
Basketball court=2400
Picnic area = 4200
Playground = 40x50 + 10x40=2400
2400+4200+2400=9000
57400-9000=48400

-10x + 5y = 10
x - 5y = -28
Answers
−10x+5y=10
x−5y=−28
Rewrite equations:
x−5y=−28
−10x+5y=10
Step: Solve:
x−5y=−28
x−5y+5y=−28+5y(Add 5y to both sides)
x=5y−28
Step: Substitute:
−10x+5y=10
−10(5y−28)+5y=10
−45y+280=10(Simplify both sides of the equation)
−45y+280+−280=10+−280(Add -280 to both sides)
−45y=−270
−45y
−45
=
−270
−45
(Divide both sides by -45)
y=6
Step: Substitute:
x=5y−28
x=(5)(6)−28
x=2(Simplify both sides of the equation)
Answer:
x=2 and y=6
