Answer: 
x + 
x = 2x - 25
Step-by-step explanation:
First, let's analyze the phrase "the sum of one-half and two-thirds the number". This would translate to:
x + x
Then it says the last part of the expression is "twenty five less than twice the number"
2x - 25
Then, equal the two parts of the equation to each other.
x + x = 2x - 25
Hope this helps! :)
Complete question is;
Keisha needs to make at least 32 costumes for the school play. Since she can make 4 costumes each week, Keisha plans to work on the costumes for at least 8 weeks.
Which inequality matches the problem?
A) x ≥ 8
B) x = 8
C) x ≤ 8
D) none of the above
Answer:
A: x ≥ 8
Step-by-step explanation:
Let the number of weeks be x.
She needs to make at least 32 costumes and plans to work at least 8 weeks. Since she makes 4 costumes per week, we can say that;
4x ≥ 32
I used greater than or equal to sign because she can't make less than 32 costumes.
Also, she can't use less than 8 weeks.
Thus; dividing both sides by 4, we have;
4x/4 ≥ 32/4
x ≥ 8
Which question ? Are you looking for?
y varies inversely with x
Answer: inverse variation
First, find a common denominator (the bottom number) Then add the tops as usual. Four and five have a common denominator of 20 so: 8/20+5/20=13/20
