Answer: Jiří is 5 years old.
Step by step:
Let x denote Jiří's age in years. Then Pamela's age is 3x. Their sum is x + 3x = 20. So we solve for x:
x + 3x = 20
4x = 20
x = 5
Jiří's age is 5 years
Answer:
x = 16
Step-by-step explanation:
Since vertical angles are equal, we can set these two expressions equal to each other to solve for x:
(1/2)x + 12 = (3/4)x + 8
12 = 0.25x + 8
4 = 0.25x
16 = x
Answer:
96 feet
Step-by-step explanation:
Velocity = distance/time
From the question , the velocity = 96 feet per sec
Time t = 1
Using the above formula
96 = d/1
Cross multiply
d = 96 feet
Answer:
Graph uploaded!
Step-by-step explanation:
<u>First, let's simplify the inequality before graphing it on the line.</u>
- 2x + 4 < 8
- => 2x < 8 - 4
- => 2x < 4
- => x < 2
<em>Now, let's graph it on the line. Please consider looking at my graph.</em>
Hoped this helped!
The whole thing is a right angle so x+67.4=90 solve for x and get 22.6 degrees
