Answer:
The correct answer is Option D. 20
Step-by-step explanation:
From the figure we get,
<RUS = 90° because RU ⊥ TS
<u>To find the value of x</u>
It is given that <RUS = 4x + 54
Therefore we can write,
4x + 54 = 90
4x = 90 - 54 = 36
x = 36/4 = 9
<u>To find RS</u>
It is given that,
RS = 3x - 7 = 3*9 -7 = 20
Therefore the correct option is Option D . 20

Answer:
10ibs=1000% 6ibs=600%
Step-by-step explanation:
Let red marbles = X.
The probability is 1 out of 5, written as 1/5
1/5 in terms of red marbles is equal to the number of red marbles divided by 5x, where 5x is the total number of marbles.
1/5 = x/5x
Now you have 5x total marbles, x red and 4x blue.
Add 5 more red and the new probability is:
(x+5)/(5x+5) = 1/3
Simplify:
3x+15 = 5x+5
Now solve for x:
Subtract 3x from both sides:
15 = 2x +5
Subtract 5 from each side:
2x = 10
Divide both sides by 2:
x = 10/2
X = 5
There were originally 5 red marbles.
Answer:
-7 = m
Step-by-step explanation:
5m − 7 = 6m
Subtract 5m from each side
5m-5m − 7 = 6m-5m
-7 = m
