Answer: A = 20
How to Solve:
Just by looking at this problem I can tell that the denominators (9 an 45) are factors of 9. So the second equation is multiplied by 5 from the first equation.
4/9 x 5
4 x 5 = 20
— -—
9 x 5 = 45
So A would be 20.
Another way to solve this would be by multiplying the 1st equations numerator with the second equations denominator:
4 x 45 = 180
Then divide 180 with the 1st equation’s denominator.
180 / 9 = 20
A = 20
R/6<= 3
Multiply 6 on both sides
Final Answer: r<= 18

<u>Answer:
</u>
The car’s rate in kilometer per minute is 1.2 kilometer/minute and in 20 min it can travel 24 kilometer
<u>Solution:
</u>
It is given that it can travel 72 kilometer per hour.
We know 1 hour = 60 min
So, the car travels in
60 min = 72 hour
Thus the cars rate in kilometer per minute is 
is 1.2 kilometer per minute.
Now we know in 1 minute the car can travel 1.2 kilometer.
Therefore in 20 minutes it will travel 1.2 
20 kilometers= 24 kilometers
Answer:
Step-by-step explanation:
From the given right angle triangle,
the hypotenuse of the right angle triangle is 13
With m∠65° as the reference angle,
y represents the adjacent side of the right angle triangle.
x represents the opposite side of the right angle triangle.
To determine the value of x, we would apply the sine trigonometric ratio which is expressed as
Sin θ = opposite side/hypotenuse. Therefore,
Sin 65 = x/13
x = 13Sin65 = 13 × 0.906
x = 11.8 to the nearest tenth
