Answer:
The answer is B : 6
Step-by-step explanation:
2.50k means 2.50 multiplied by a number and the inequality means 20 is less than 2.50k + 5.50. 2.50 multiplied by 6 equals 15 and 15 plus 5.50 is 20.50 which is greater than 20.
Answer:
<u>The correct answer is that 600 miles per hour are equivalent to 965.4 kilometers per hour</u>
Step-by-step explanation:
1. Let's check the information given to resolve the question:
Convert 600 miles per hour to kilometers per hour
2. Let's proceed with the conversion:
1 mile per hour = 1.609 kilometers per hour
then:
600 miles per hour = 600 * 1.609 kilometers per hour
600 miles per hour = 965.4 kilometers per hour
<u>The correct answer is that 600 miles per hour are equivalent to 965.4 kilometers per hour</u>
H(x) = -5x - 10
h(-2) = -5(-2) - 10
h(-2) = 10 - 10
h(-2) = 0
The solution is 0.
Answer:
x = 60
Step-by-step explanation:
Direct variation is of the form
y= kxz
We know x =40 and y =10 and z= 20
10 = k * 40 * 20
10 = k * 800
Divide each side by 800
10/800 = k
1/80 = k
The equation becomes
y = 1/80 xz
Let y = 30 and z = 40 and find x
30 = 1/80 * x * 40
30= 40/80 x
30 = 1/2x
Multiply each side by 2
2 * 30 = 2 * 1/2 x
60 = x
