Answer:
I think 12 but I gave it a shot
12/14=6/7
Because you divide by 2.
Answer:
there are three different types of answers to this and all of them have to do with the perspective of pi
1) if you don't want to see the decimals and you want to leave pi alone your answer would be this
3pi
2) if you want to solve for pi it would be
9.43 respectively
3) if you want pi to just be narrowed down to 3 digits 3.14 your answer would be
9.42
Step-by-step explanation:
formula
C=2*pi*R
plug in
2*pi*1.5
Subtract 2 from both sides.
Your equation will be: 4x+3=x
Subtract 4x from both sides.
Yoir equation will be: 3= -3x
Divide by -3x on both sides.
Your final answer: x=-1
Answer:
The price of the cell phone without the coupon= $500
Step-by-step explanation:
Step 1: Express discounted amount
The discounted amount can be expressed as a function of the original cost of the phone as follows;
D=r×A
where;
D=discounted amount
r=coupon rate
A=original price of the cell phone before the coupon
In our case;
r=45%=45/100=0.45
A=a
replacing;
Discounted amount=(0.45×a)=0.45 a
Step 2: Amount she pays up
Amount she pays=Original cost of cell phone-discounted amount
where;
Amount she pays= $275
original cost of cell phone=a
discounted amount=0.45 a
replacing;
$275=a-0.45 a
0.55 a=275
a=275/0.55
a=500
The price of the cell phone without the coupon= $500
