The sum of 3 consecutive even integers is 78. What is the largest of the integers?
Maksim231197 [3]

Answer:

is the sum 78 or 7,878 (i.e. was there a stutter)?

In any event, this sum must be even, so 3 consecutive even integers would be n, n+2 & n+4 whose sum is 3n + 6.

Set that to either 78 or 7878, whichever is intended, & solve for n.   If 78 is their grand total, then those 3 consecutive even numbers have to be 24, 26 & 28.

No stress!  Just logic! Keep the faith!

The perimeter of (the distance around) ABCD is 66, and DC is twice as long as CB. How long is AB?
ArbitrLikvidat [17]

Answer:

AB=22\ units

Step-by-step explanation:

we know that

In this problem ABCD is a rectangle

so

DC=AB

BC=AD

Let

BC ---> the length of rectangle

DC ---> the width of rectangle

we know that

The perimeter of rectangle is equal to

P=2(BC+DC)

we have

P=66\ units

so

66=2(BC+DC)

simplify

33=BC+DC ----> equation A

DC=2BC ----> equation B

substitute equation B in equation A

33=BC+2BC

Solve for BC

Combine like terms

33=3BC

Divide by 3 both sides

BC=11\ units

<em>Find the value of DC</em>

DC=2BC ----> DC=2(11)=22\ units

Remember that

DC=AB

therefore

AB=22\ units
