Answer:
Number of new weeks = 20 week
Step-by-step explanation:
Total money saves = $50 x 30
Total money saves = $1,500
Find:
Number of new week
Computation:
Total money saves = Number of money save per week x Number of new weeks
1,500 = 75 x Number of new weeks
Number of new weeks = 20 week
Lets name the shortest piece a, the medium b and the longest c
Together they are 90inches

The longest is 30 inches longer than the shortest

The third piece is half the lenght of the longest

So if you place c=a+30 in the other 2 equasions you get

And

Now if you put this 2 toghether u get

Multyplied by 2


Meaning that a=18inches
Now that we have the lenght of a we put it in the previous equasion

So b=48/2 which means b=24inches
And together they must be 90 so

C=48inches
Answer: -2x - 10
Steps: -2(x+5)
Apply the distributive law [ a(b + c) = ab + ac ]:
a = -2, b = x, c = 5
-2x + (-2) × 5
Apply minus/plus rules: -2x - 2 × 5
Multiply the numbers: 2 × 5 = 10
-2x - 10
