Answer:
A. $2.89(m)=$40
B. 13 songs
Step-by-step explanation:
$2.89(m)=$40
m=$40/$2.89
m=13.84
She can download a maximum of 13 songs
Check:
$2.89 (13 songs)=$37.57
$40-$37.57=$2.43 left on her gift card
m=13.84, check that 0.84 of the cost of a song is left over 0.84*$2.89=$2.43
Answer:
$65m + 125 = 1165
Step-by-step explanation:
Answer:
9 and 6
Step-by-step explanation:
Write down the system.
The two numbers are x and y.
We are therefore given:
x+y=15
x-y=3
I will solve this for elimination since it is already setup for it.
I will add the columns since both equations are in the same form.
2x+0y=18
2x =18
Divide both sides by 2:
x =18/2
Simplify:
x =9
So if x+y=15 and x=9, then y=6.
The two numbers are 9 and 6.
Test:
9+6=15
9-6=3
You just need to use a variable name to represent the number of points and make it greater than 100.
Use x as the number of the variable, then x has to be greater than 100.
In mathematical language you use the signs >, ≥, < and ≤.
> means greater than
≥ means greater than or equal to
< means less than
≤ means less than or equal to.
Here you need to state that your variable x is greater than 100, that is
x > 100.
That is inequality you wanted.
Answer: x > 100
