Answer: Eric still needs of a deck.
Step-by-step explanation:
You know that:
- Eric need 1/2 deck of playing cards.
- Eric has 2/7 of a deck.
Therefore, to find the fraction of a deck that Eric still needs, you must subtract 1/2 and 2/7:
- Find the least common multiple of the denominators:
- Now, you can make the subtraction:
Therefore, he still needs of a deck.
Answer:
A
Step-by-step explanation:
Parallel lines are two lines that are next to each other and extend infinitely in both directions without every meeting.
The correct answer is: [C]: " -5 ΙxΙ = 25 " .
______________________________________________
In this answer choice, when you divide each side by "-5" ;
you get: " ΙxΙ = -5 ;
If x = 5, the result is "5" ; NOT "-5" .
If x = -5, the result is "5" ; NOT "-5" .
The "absolute value" of a value is always "zero" or greater.

Supplementary angles add to equal 180 degrees. If two angles are supplementary and one angle measures 10x degrees and the other angle measures 70 degrees, you can set the sum of 10x and 70 equal to 180 and solve algebraically for x.
180 = 10x + 70
110 = 10x
11 = x
Answer:
x = 11
