Answer:
Option C - 
Step-by-step explanation:
To find : Which of the following expressions represents the distances between -4 and 5 on the number line?
Solution :
According to number line,
<-----------|----|------|----|-----|----|---|----|----|----|-----|----|---------------->
-∞ -5 -4 -3 -2 -1 0 1 2 3 4 5 6 +∞
The distance between -4 and 5 is given by,
Solving the expression,
Therefore, The expression represents the distances between -4 and 5 on the number line is
So, Option C is correct.
Answer:
B. 60deg
Step-by-step explanation:
Both the sum of the third angle in the triangle and x has to be 180deg, as they sum to a half angle;
and the sum of angles in any triangle is 180deg.
We know that x = 180deg - (180deg - 28deg - 32deg) = 180deg - 180deg + 28deg + 32deg = 60deg
Also, note that x is drawn as smaller than a right angle. Unless the picture was made specifically to confuse us, we know that the only answer could be B.
Answer:
Factor
25 out of 75x−50.
25 (3x-2)
Step-by-step explanation:
Answer:
Step-by-step explanation:
65 ÷ b + 8 x 4 = 20
Putting value of b = 5 in the equation
65 ÷ 5 + 8 x 4 = 20
13 + 8 x 4 = 20
13 + 32 = 20
45 = 20
Bringing like terms on one side
45 - 20 = 25
