Answer: C
Step-by-step explanation:
Okay first set a comparison since the two triangles are similar
x-1/20=x-1+27/3x+8
x-1/20 = x+26/3x+8
cross multiply
20x+520=3x^2+8x-3x-8
3x^2-15x-528=0
3(x^2-5x-176)=0
im kinda lazy to factor this out so i used an online calculator right here but factor it out like a good kid
x=16, x=-11
it has to be positive so x=16
C
Answer:
X = 32 meters.
Step-by-step explanation:
- Let the unknown distance be X.
<u>Given the following data;</u>
- Distance = 8 meters per hour
- Time = 4 hours
To find how many meters he would cover in four hours;
1 hour = 8 meters
4 hours = X meters
Cross-multiplying, we have;
X = 8 * 4
<em>X = 32 meters.</em>
This is
{HH, TT, TH, HT} where H = head and T = tail
The answer would be 7/4 because you would just divide both the 21 and 12 by 3
Answer:
<h2>The answer is 7.47</h2>
Step-by-step explanation:
In this problem we are going find the natural logarithmic of the numbers involved and solve for x

from tables
<h3> ln 65= 4.17</h3>

taking the exponents of both sides we have
