D + 3r = 15
d = r + 3
r + 3 + 3r = 15
4r + 3 = 15
4r = 15 - 3
4r = 12
r = 12/4
r = 3 ....he bought 3 roses, at $ 3 per rose = $ 9 <==
d = r + 3
d = 3 + 3
d = 6....he bought 6 daisies, at $ 1 per daisy = $ 6
30 x ( 20 / 100 )
= 30 x ( 1 / 5 )
= 30 / 5
= 6
Thank you very much.
Answer:
B 6,17
Step-by-step explanation: If you plug in the value of x from each of the choices only b gives the correct value of y. If you put 6 in the place of x in y= 3x-1 then y= 18-1 which is 17, and it does say 17 in 6,17.
ANSWER
5.2387 and 5.2437
EXPLANATION
To round a decimal to the nearest hundredth means we should round to two decimal places.
To round to two decimal places we consider the third decimal place.
When we round 5.2387 to the nearest hundredth, we obtain 5.24 because the third decimal place is greater than or equal to 5 so we round up.
When we round 5.2437 to the nearest hundredth, we get 5.24 because the third decimal place less than 5 so we round off.
In fact there are infinitely many decimals that will round to 5.24 when rounding to the nearest hundredth.
