7x - 16 = 2(2x - 5)
7x - 16 = 4x - 10
7x - 4x = 16 - 10
3x = 6
x = 2 

y = 7*2 - 16 = 14 - 16 = - 2

Answer
( 2; - 2)

Karen is typing a 4,000 word essay. She can type at about 30 words per minute. If she types for 45 minutes on Monday and 55 minu
horrorfan [7]

Answer:The number of words that she would still have to type to finish her essay is 1000

Step-by-step explanation:

Karen is typing a 4,000 word essay. She can type at about 30 words per minute. This means that if her rate remains constant, the total number of minutes that it will take her to finish would be

4000/30 = 133.33 minutes.

If she types for 45 minutes on Monday, it means that the total number of words that she typed on Monday would be

45 × 30 = 1350 words

If she types for 55 minutes on Tuesday, it means that the total number of words that she typed on Tuesday would be

55 × 30 = 1650 words

Total number of words typed on Monday and Tuesday would be

1350 + 1650 = 3000 words

The number of words that she would still have to type to finish her essay would be

4000 - 3000 = 1000 words

Question 4 options: Parallelogram ABCD is a rectangle. AX = 3y − 5BD = 5y What is the value of y? Enter your answer in the box.
kari74 [83]

⇒If parallelogram A B CD is a rectangle, then Diagonals of parallelogram that is of rectangle will be of equal Length.

That is , Diagonal AC = Diagonal B D

⇒Given, AX= 3 y- 5

So, AC= 2 × (3 y- 5)→→[Diagonals of Parallelogram Bisect each other]

And, B D = 5 y

So,A C = B D ⇒→→Diagonals of a rectangle are equal.]

→2 ×(3 y - 5) = 5 y

→ 6 y - 10 = 5 y →→[Using Distributive Property of subtraction with respect to multiplication]

Combining Like terms that is Variables with Variables and Constant with Constant.

→ 6 y - 5 y = 10

→  y = 10
