Given:

Total money need to spend at most = $45

Money spent on Yoga ball = $15

We need to find how much money she can still spend on her friend birthday gift.

So we can say that;

Money spent on Yoga ball plus money she can still spend on her friend birthday gift should be less than or equal to Total money need to spend.

framing in equation form we get;

The Inequality representing money she can still spend on her friend birthday gift is .

On solving the the above Inequality we get;

we will subtract both side by 15 using subtraction property of Inequality.

Solve equation: -3|d-5|=-6

gulaghasi [49]

Answer:

d = 7, 3

Step-by-step explanation:

First, you need to isolate the absolute value

-3|d - 5| = -6

divide both sides by -3:

|d - 5| = 2

break into 2 equations:

d - 5 = 2, d - 5 = -2

solve both equations and collect solutions:

d = 5 + 2, d = 5 - 2

d = 7, 3
