If R represents Reggie's time, the total time for the team is
.. R +(R +2.45) +(R -3.81) = 3R -1.36
.. = 3*57.12 -1.36
.. = 170.00 . . . seconds

Need help breaking this down step by step <br><br> Distribute and combine <br><br> 1/2(n-8)+7-n

PIT_PIT [208]

Answer:

$3-\frac{1}{2}n$

Step-by-step explanation:

We will use the distributive property shown below to break it down first.

Distributive Property: $a(b-c)=ab-ac$

The expression is:

$\frac{1}{2}(n-8)+7-n$

Let's distribute:

$\frac{1}{2}(n-8)+7-n\\=\frac{1}{2}(n)-\frac{1}{2}(8)+7-n$

Now, we multiply:

$\frac{1}{2}(n)-\frac{1}{2}(8)+7-n\\=\frac{1}{2}n-4+7-n$

Now we combine like terms (variables and numbers separately):

$\frac{1}{2}n-4+7-n\\=-4+7-n+\frac{1}{2}n\\=3-\frac{1}{2}n$

This is the simplified expression.

I completed 2/3 of my project last month and 1/4 of it this week what fraction is completed

aleksandr82 [10.1K]

Answer: $\frac{11}{12}$

Step-by-step explanation:

Since we are looking for the total fraction completed , all we need do is to add the fraction completed last month and the fraction completed this week , that is

$\frac{2}{3}$ + $\frac{1}{4}$

The L.C.M is 12 , so we have

$\frac{2}{3}$ + $\frac{1}{4}$ = $\frac{8 +3}{12}$

= $\frac{11}{12}$

Therefore 11/12 is completed
