Answer:
R = 3/50
Step-by-step explanation:
If you are trying to solve for a variable,
1. Simplify both sides of the equation:
3/4 - 5/6R = 7/10 will now be (-5/6r) + 3/4 = 7/10
2. Add -3/4 from both sides of the equation:
(-3/4) + 3/4 = 0 and (-3/4) - 7/10 = -1/20.
You will be left with: -5/6r = -1/20.
3. Divide both sides by (-5/6).
(-5/6r) / -5/6 = 1R or just R. (-1/20) / -5/6 = 3/50
You are left with the answer:
R = 3/50

ANSWER:
2.33 foot
STEP-BY-STEP EXPLANATION:
We can calculate the distance from the staircase to the wall, by means of the trigonometric cosine ratio, which is the following:

Replacing and solving for x:

The distance would be 2.33 foot
Let x = liters 20% solution to be added
then
.12(12) + .20x = .14(12+x)
.12(12) + .20x = .14(12+x)
1.44 + .20x = 1.68 + .14x
.20x = .24 + .14x
.06x = .24
x = 4 liters

Answer:
E -->R
D-->K
O-->O
Step-by-step explanation:
Assuming you are asking for congruent parts, correspondence is the part which corresponds and is also equal.
Here Angle E corresponds and is congruent to Angle R in these congruent triangles.
Angle D is congruent and corresponds to Angle K for these congruent triangles.
Angle O is equal to Angle O as they are vertical angles across a vertex.
