Answer:
13
Step-by-step explanation:
The product of two negative numbers is positive. The absolute value of a number is its magnitude written with a positive sign.
6 -2(-1) +|-5|
= 6 + 2 + 5
= 13
a) if AB = CD, then 3CD = 3(CD + 1) NOT TRUE
example: AB = CD = 1, then 3CD = (3)(1)=3 and 3(CD + 1) = 3(1 + 1) = 3(2) = 6
b) if AB = CD, then AB - CD = A - C + B - D NOT TRUE (it does not make sense because A, B, C and D are points)
c) if AB = CD, then AB + EF = CD + EF TRUE
because
AB = CD |add EF to both sides
AB + EF = CD + EF
d) if AB = CD, then 2AB = 2A + 2B NOT TRUE (it does not make sense because A and B are points).
<span>What is the quotient of 7035/15
469 is equivalent to 7035/15
because 7035/15=469</span>
4: 3/5 does not belong because when u convert the other 2, to make the denominators the same u always get 2/5
6: Yes does form a proportion multiply 1/5 by 6/6
8: No
-14x=70
Dive both sides by -14, and you end up with:
x=-5
hope this helps!
