The value of a two-digit number exceeds twice the sum of its digits by 19. the tens digit is two less than the units digit. find the number.

Answer with Step-by-step explanation:

Let the ones digit of the number be y

and tens digit of the number be x.

The tens digit is two less than the units digit.

i.e. x=y-2

The value of the number exceeds twice the sum of its digits by 19.

i.e. 10x+y=2(x+y)+19

10(y-2)+y=2(y-2+y)+19

10y-20+y=2(2y-2)+19

11y-20=4y-4+19

11y-4y=20-4+19

7y=35

dividing both sides by 7, we get

y=5

Putting value of y in x=y-2, we get

x=3

10x+y=10×3+5

         =35

Hence, the two digit number is:

35

a. turk and mcalister

b. howard, mission, and market

c. yes. since streets end some do not cross yet are not parallel to others. example: mcalister and 5th

step-by-step explanation:

parallel lines are lines which do not intersect ever and look a lot like railroad tracks. turk, mcalister and golden gate are examples of these.

intersect are streets which cross each other and a car on one can reach the other. howard, mission, and market intersect with 6th.

skew lines are lines which neither intersect nor are parallel. these lines exist here because some streets end and never intersect another like mcalister and 5th.
