Acar traveling 70 miles per hour travelled one hour longer than a truck traveling 60 miles per hour. if the car and truck travelled a total of 330 miles, for how many hours did the car and truck travel all together?

5

Step-by-step explanation:

60 x + 70(x+1)=330

60x+70x+70=330

130x=260

x=2

x+1=3

so the answer is 5 hope i helped <33

the smallest possible measurement of the width is 14 feet

step-by-step explanation:

let's assume length of parallelogram is 'l'

width of parallelogram is 'w'

the perimeter of a parallelogram must be no less than 40 feet

so, we get

we are given

length of parallelogram is 6 feet

so,

l=6

we can plug it

now, we can solve for w

subtract both sides by 12

divide both sides by 2

and we get

so,

the smallest possible measurement of the width is 14 feet

the answer is (-8,-5)

step-by-step explanation:

the endpoint to midpoint is half the length. the length is (-2,-1) so when you are at the midpoint just add it to it to find your answer -6+(-2)= -8 and -4+(-1)=-5 so (-8,-5)
