Answer:
Hi, I think your question is incomplete. But I'll assume you're asking a party of 5 wants to add a tip of 20% to their total 175 dollars bill, how much do each person needs to pay?
Step-by-step explanation:
Firstly, calculate the percentage: 175 x 20% is 35, so 35 + 175 is 210.
210 ÷ 5 (Num. Of people in party)
Is 42 dollars. <em><u>Therefore each people need to pay 42 dollars. </u></em>
Step-by-step explanation:
4 H (Hundreds)
5 T(tens)
9 ones
3x3= 9
50x3= 150
100x3= 300
add 300+150+9= 459
Answer:
Step-by-step explanation:
Let's put in some numbers to make this easier to understand.
Let's say she has to travel 20 km.
On Monday, she travels at 4 kph. This takes 5 hours.
On Tuesday she travels 25% faster, at 5 kph. This takes 4 hours.
To figure percent reduction we take
100 % * (old - new) / old
100 % * (5 hr - 4 hr ) / 5 hr
100 % * 1 hr / 5 hr
100 % * 0.20
20% reduction.
Answer:
a= 1/2b
Step-by-step explanation:
a+b=3a
a=3a-b
a-3a= - b
- 2a= - b
a=1/2b
Y=x^2-4x+8 and 4x+y=12 so y=12-4x, insert y in the quadratic to get
12-4x=x^2-4x+8
12=x^2+8
0=x^2-4=(x-2)(x+2)
So the solutions are x=2 and x=-2.
