Answer:
angle B=120º
Step-by-step explanation:
15+45=60
We know that all triangles have angle measures that equal 180
So 180-60=120
angle B=120º
Answer:
<u>A</u>
Step-by-step explanation:
<u>Given</u>
<u>Solving</u>
- Take the square root on both sides
- √x² = √9/4
- ⇒ x = 3/2
- <u>Option A is the correct option.</u>
The first step for absolute value equations is to isolate the expression contained within the absolute value bars:
3|2x+4|-1 = 11
3|2x+4| = 12
|2x+4| = 4
so |2x+4| is 4 units away from 0 on a number line, but we don't know in which direction -- negative or positive? you'll have two answers.
2x+4 = 4
AND
2x+4 = -4
solve both of those two step equations and you'll get
x = 0
AND
x = -4
so 0 and -4 are your solutions.
Answer:
20 minutes( 0.3333 hours) after they leave the station will they be 50 km apart, if the Two trains on opposite tracks leave the same station at the same time.
Step-by-step explanation:
One train travels at an average speed of 80 km/hr and the other travels at an average speed of 70 km/hr.
X 65%
———— = ———-
90 100
1) multiply across
90 • 65 = 5,850
2) divide what’s left over.
5,850 / 100 = 58.5
