Step-by-step explanation:
Answer:
See proof below
Step-by-step explanation:
Given the expression 2/4-x = 10/4+x
Cross multiply
10(4-x) = 2(4+x)
10(4) - 10x = 2(4)+ 2x
40 - 10x = 8 + 2x
-10x - 2x = 8 - 40
-12x = -32
Multiply both sides by -1
-1(-12x) = -1(-32)
12x = 32
This shows the required expression
Answer:
Step-by-step explanation:
<u>Find b first:</u>
- b = 3/x + 3/y
- b = (3x + 3y)/xy
<u>Find 1/b:</u>
- 1/b = 1 : (3x + 3y)/xy
- 1/b = xy / (3x + 3y)
When a whole number is multiplied by 1,000 the product is the whole number with 3 zeros added behind it.
Answer:
7,2,3
Step-by-step explanation:
Congruent angles means that both angles have same measure.
Remember that if both lines cross-intersect each others, both form same measure.
Therefore:-
angle 6 = angle 7
Assume that both lines are parallel, we can say that angle 6 = angle 2
Since angle 6 = angle 2 and angle 2 = angle 3 via cross-intersect, that means angle 6 = angle 3 as well. angle 6 = angle 3 is alternate interior angle theorem.
Thus:- angle 7, 2 and 3 both are congruent
