$1.25
you spent $6.25 on everybody ($20-$13.75)
and $6.25 divided by 5 is $1.25 :)
Answer: y=2/3x+3
*Remember the original equation in slope-intercept form*
y=mx+b
*label that with what each letter stands for*
m=slope/rate of change
x=variable
b=y-intercept
*Substitute this information into the equation
y=2/3x+3
Hope this helps comment below for more questions :)
This is a linear, non-proportional relationship.
It is linear because there is a constant slope, or rate of change.
It is not proportional because it does not go through the origin. The y-intercept would be the $25 starting fee.
You need 5 more gallons for a full tank.
Since it takes 10 gallons to increase the gauge from 1/4 to 3/4 (change of 2/4 which is the same as 1/2), it must have taken 10 gallons to fill up to halfway for the tank.
Thus the full amount would be 10*2 = 20 gallons
However, since there is already 3/4 gasoline in the tank, we only need an extra 1/4 of 20 for it to be full.
So, 20*1/4 = 5
We need to add 5 gallons for a full tank.
Answer:
22) 119
24) 15
Step-by-step explanation:
22) 61 + b = 180 <-- supplementary because on the same line
b = 119 <-- subtracted 61 from both sides
24) 87 + (6x + 3) = 180 <-- supplementary because on the same line
87 + 6x + 3 = 180 <-- take out parantheses
90 + 6x = 180 <-- add like terms
6x = 90 <-- subtracted 90 from both sides
x = 15 <-- solve for x by dividing 6 from both sides
