Answer:
vehicle a needs 72 gallons
while vehicle b needs 28
with this the equation is simpaly 72-28 which is 44
so vehicle a needs 44 more gallons of gas for da trip

The answer is 10 your welcome
Answer:
48
Step-by-step explanation:
let s be the snowman, g be the girl, and t be the christmas tree
2s+g=24
2t+2ts=132
3t+2g=26
subtract 2 times the first equation from the third one to get
3t-4s=-22
from the second equation we can deduce
2t(1+s)=132
t(1+s)=66
t=66/(1+s)
Substitute:
3(66)/(1+s)-4s=-22
3(66)/(1+s)=4s-22
3(66)=(4s-22)(1+s)
3(66)=-18s+4s^2-22
4s^2-18s-220=0
using the quadratic formula, we get s = 10, s = -5.5.
2(10)+g=24
g=4
2t(1+10)=132
2t=12
t=6
So 2s+t*g= 20+6*4=48
you would get a different solution for the negative s, but since snowmen cannot be negative, 48 is the answe.r
Answer:
y = -1/6x + 0
Step-by-step explanation:
Using the equation of line
y_2 - y_1 / x_2 - x_1 = y - y_1 / x_1
Using the information we are provided with
( -3, 0.5)(3 , -0.5)
y_1 = 0.5
x_1 = -3
x_2 = 3
y_2 = -0.5
-0.5 - 0.5 / 3- (-3) = y - 0.5 / x - (-3)
-0.5 - 0.5 / 3 +3 = y - 0.5 / x + 3
-1 / 6 = y - 0.5 / x + 3
Cross multiply
-1(x + 3) = 6(y - 0.5)
Open the brackets
-x - 3 = 6y - 3
-x - 3 + 3 = 6y
-x + 0 = 6y
Divide through by 6 to get y
Following the eqn y = mx + C
-x + 0 / 6 = 6y / 6
y = -x + 0 / 6
We can separate it
y = -x / 6 + 0/6
y = -1/6x + 0
Therefore, the equation of the line is
y = -1/6x + 0
