Answer:
Charles practiced for the relay race for D. 9 hours last week.
Step-by-step explanation:
First, I would find the ratios the ratios for converting hurdle to javelin and javelin to relay.
Hurdle : Javelin ; 5 : 1.5
Javelin : Relay ; 2.5 : 5 or 1 : 2
Next, find the factors compared to the original numbers for hurdle to javelin.
15 / 5 = 3
To find the amount of javelin time they did, multiply 1.5 by the factor we got, 3.
1.5 * 3 = 4.5
Finally, double 4.5, since Charles does twice as much relay than he does javelin.
4.5 * 2 = 9 hours
9. L’(-1,-3) Z’(-5,-5) F’(-4,-2)
10. B
I think these are right if they aren’t I’m sorry
Answer:
d = 2.75 or 11/4
Step-by-step explanation:
15 = 5 + 4(2d - 3)
15 = 5 + 8d - 12
15 = 8d - 7
<u>+7 + 7</u>
22 = 8d
22/8 = d
2.75 = d
Check:
15 = 5 + 4(2(2.75) - 3)
B. Half the speed of the car. and C. The number of different colors on the page.
Variables are symbols for unknown values, so you have to find the statements that contain an unknown value.
A. 27 ⇒ The point value is known, so there is no variable.
B. 
X ⇒ Since the speed of the car is unknown, the variable X represents the speed of the car. This variable is multiplied by or divided by 2 to get half the speed of the car.
C. X ⇒ The number of different colors is not known, so the variable X represents the number of different colors.
D. 80 ⇒ There is nothing unknown in the statement.
