We've helped you with several problems. Now it's your turn to show what you've learned.
I'll be glad to check your answers.
For the first one.
n+6.3−6.3=16.3−6.3
n=10
Second
d+20=2.5
d+20−20=2.5−20
d=−17.5
Yes. Both of those are correct.
Third
5d/5 = 17.1/5
d=3.42
Right. :-)
To solve each equation, we'll go through the steps one by one.
1. n + 6.3 = 16.3
To isolate n, we can subtract 6.3 from both sides of the equation.
n + 6.3 - 6.3 = 16.3 - 6.3
n = 10
2. d - (-20) = 2.5
Simplify the double negative by removing the parentheses.
d + 20 = 2.5
Next, subtract 20 from both sides of the equation.
d + 20 - 20 = 2.5 - 20
d = -17.5
3. 5d = 17.1
To solve for d, we'll divide both sides of the equation by 5.
(5d)/5 = 17.1/5
d = 3.42
4. m / -4 = -2.95
To isolate m, we'll multiply both sides of the equation by -4.
(-4)(m / -4) = -2.95(-4)
This simplifies to:
m = 11.8
So the solutions to the equations are:
1. n = 10
2. d = -17.5
3. d = 3.42
4. m = 11.8
