2 times as much.
(In the cereal aisle at Costco they always have 2 boxes a pack)
Answer:
A. 432=18x
B. 22-see explanation
C. 24
D. See if your rounded answer and the actual answer are close.
Step-by-step explanation:
A. He buys a new phone for $432, and pays each month. We will use the variable x, and "x" will represent how many months he pays. It says that he pays $18 per month, so the equation would be 432=18x.
B. We need to isolate x, and to do this we have to divide 432 by 18. To approximate this answer, round 432 to 440 and 18 to 20. Now, divide 440 by 20. We get 22, so this will be the estimation.
C. Divide 432 by 18. We get 24.
E. You can see if it is reasonable if they are close in value.
Answer:
x=((log(81))/(log(3))+2)/3
Step-by-step explanation:
so what you want to do is get 3x-2 out of the exponent
you can do that by using log
so apply log to both sides and you get
log(81)=(3x-2)log(3)
the 3x-2 is moved in front of the log due to a log rule
then (log(81))/(log(3))=3x-2
(log(81))/(log(3))+2=3x
((log(81))/(log(3))+2)/3=x
then use a calculator to find the exact value
hope this helps im sorry my explanation is a bit confusing, ask any questions you have
Answer:
Step-by-step explanation:
hold on how much does john have?
Answer:
Jasmine;
more
Step-by-step explanation:
Amie used 7/9 yard of ribbon, and Jasmine used 5/6 yard of ribbon. We can compare these fractions easier if they have the same denominator (bottom number). Let's get a common denominator for these fractions.
7/9 x 2/2 = 14/18
Amie used 14/18 yards of ribbon
5/6 x 3/3 = 15/18
Jasmine used 15/18 yards of ribbon
Which is greater: 14/18 or 15/18? 15/18
To find out how much more, just subtract 14/18 from 15/18:
15/18 - 14/18 = 1/18
Jasmine used 1/18 yards more ribbon than Amie
