Hello,
Answer A
d :the distance in miles
t: the time in hours
v: the speed in miles/hours (vistesse)
d=v*t
==>d=40*4=160(mi)
d=55*x=160==>x=160/55=2.909090... (mi/(mi/h)=h)≈2.91(hours)
Answer:
A
Step-by-step explanation:
If it’s 80 less than, your subtracting and then 4 times a number is 4x so your answer is 4x-80
To find the size of each angle, divide the sum, 540º, by the number of angles in the pentagon. (which is the same as the number of sides). There are 108° in each interior angle of a regular pentagon. This process can be generalized into a formula for finding each interior angle of a REGULAR polygon ...
3y+4+3y-y=-6
6y-y+4=-6
5y+4=-6
5y=-10
y=-2
