Carlos driving time = Xh, Maria driving time = Yh.
55m/h*Xh + 47m/h*Yh = 197m
Together, they both drove 3,8 hours, so Carlos drove 3,8 hours minus the time Maria drove;
55m/h*(3,8h-Yh)+47m/h*Yh = 197m
55m/h*3,8h - 55m/h*Yh + 47m/h*Yh = 197m
<span>209m - 8m/h*Yh = 197m
8mY = 209m - 197m
8mY = 12m
Y = 12m/8m
Y = 1,5
</span>The correct answer is 1,5 hours.
Answer:
beggining poit:3 second point (potentially): 1,5
Step-by-step explanation:
in the y intercept 3 is it so which ever has a 3 as the starting point there could be an option
for the 2x part that is the slope otherwise known as rise over run so what you do is that you turn it to a fraction over or under 1 meaning you rise for 2 and go to the right 1
rise 2
_
run 1
in order to rise 2 you go up 2 from the y intercept(3) and in order to run you go right since its a positive
once you plot those two dots then you draw a line across
Combine like terms so add 4b and 15b together and add 7 and 3 together and then the answer would be 19b-10
Answer:
56
