Answer:
StartFraction 7 over 2 EndFraction can be used to find the unit rate if one divides 7 by 2 and compares the result to 1
Step-by-step explanation:
we know that
The formula to calculate the slope between two points is equal to
we have the points
B(2, 7) and D(4, 14)
substitute the values
The unit rate is
therefore
StartFraction 7 over 2 EndFraction can be used to find the unit rate if one divides 7 by 2 and compares the result to 1

Step-by-step explanation:
Answer:
C) y is equal to 10.5x
Step-by-step explanation:
$31.50 is charged for <em>3 </em>hours so, for 1 hour we need to divide 31.50 by 3, which results in 10.50. So 1 hour of babysitting is $10.50
this is because x is equal to the number of hours they babysit. we do not know the actual so it is replaced with x
and y is equal to the sum of 10.5x because we multiply the number of hours worked, and the amount per hour.
1. 1 1/8= 18/16
5/16*2= 10/16
4/16*2= 8/16
9/16= 9/16
1/2= 8/16
18/16 + 10/16 + 8/16 + 9/16 + 8/16= 53/16
Simplify:
4 & 5/16sq ft
2. All you do is multiply that by 3... so 4 & 5/16 = 53/16 53/16*3 = 159/16 = 9 & 15/16 sq ft
Write and solve an equation of ratios:
oil 8 x
---- = ---- = -----------
vin 5 7 liters
Then 5x = 56, and x = 56/5 liters (of vinegar)
