Answer:
3/14
Step-by-step explanation:
5/7 minus 1/2 is 5/7 - 1/2
5/7 and 1/2 are both called proper fractions. 5 and 1 in each fraction are called the numerator while 7 and 2 are called denominators
5/7 - 1/2
Step one
Find the lowest common multiple (LCM) of the denominators of each fractions
Multiples of 7
7 x 1 = 7
7 x 2 = 14
7 x 3 = 21
Multiples of 2
2 x 1 = 2
2 x 2 = 4
2 x 3 = 6
2 x 4 = 8
2 x 5 = 10
2 x 6 = 12
2 x 7 = 14
The lowest common multiple of 2 and 7 is 14
Step 2
The LCM of 2 and 7 becomes the common denominator for both fractions.
14/7 = 2
14/2 = 7
5/7 - 1/2 = [2(5) - 7(1)]/14 = (10 - 7)/14
= 3/14
4) 28 this is the right answer
Answer:
<u>The three true options are B, C and E.</u>
Step-by-step explanation:
Let's simplify the expression that represent the score of Javier in a game of mini-golf:
3x + x + 5 – 2x
2x + 5
Which statements are true about the parts of the simplified expression? Select three options.
A. The constant is 2.
It's false. The constant is 5.
B. The coefficient is 2.
It's true. The coefficient of x is 2.
C. The constant is 5.
It's true.
D. The coefficient is 5.
It's false. 5 is the constant and the coefficient of x is 2.
E. There are two terms.
It's true. The two terms are 2x and 5.
<u>The three true options are B, C and E.</u>
True! The slopes are opposite reciprocals (aka perpendicular lines)
