The sum of two consecutive integers is 77 find the integers

Hello from MrBillDoesMath!

38,39

Discussion:

Call the first integer "n". Then

n + ( n+1) = 77                 =>

2n + 1      = 77                 => subtract 1 from both sides

2n            = 77 - 1 = 76   => divide both sides by 2

n = 76/2 = 38

The first integer is n = 38 and the next consecutive one (= n+1) is 38 + 1 = 39.  Finally, 38 + 39 = 77

Thank you,

MrB

the equation cos(35) =a/25 can be used to find the length of bc what is the length of bc? round to the nearest tenth

step-by-step explanation:

step-by-step explanation:

given perimeter: 28cm

length: 9cm

atp,

2(l+w)=p of the reactangle

2(9+x)=28

18+2x=28

2x=28-18

x=10/2

x=5

therefore width is 5 cm
