Answer:
is the required inequality
Step-by-step explanation:
Let the number of songs = m.
The cost of downloading 1 songs = $1.29
So, the cost of downloading 'm' songs =
dollars
Since, the maximum amount she can spend on downloading songs is $20.
So, we get the inequality, 
Hence, the inequality representing the situation is
.
Answer:
The new rate should be $56.67 per day
Step-by-step explanation:
Proportion states that the two fractions or ratios are equal.
As per the statement:
Normal rate per day = $45
To find the new rate:
Let new rate be x per day
By definition of proportion:

By cross multiply we have;

Divide both sides by 100 we get;

Simplify:
x = $56.7
Therefore, the new rate should be $56.7 per day
Answer: x =104
Step-by-step explanation:
If we draw the black line shown in the figure, two isosceles triangles are formed, and the base angles of the isosceles triangles are the same. The red angles are the same and the green ones too. The 104 degree angle is the sum of the red angle and the green angle, and x is also the sum of the red angle and the green angle, therefore x = 104.
-120 ÷ 15 = -8.
Hope this helps.
we are given

Since, we have to solve for x
so, we will isolate x on anyone side
step-1: Add both sides 27


step-2: Divide both sides by 7


now, we can simplify it
