3. Two consecutive even integers have a sum of 26. What are the two
integers?

The two consecutive no. Are 12 and 14

Step-by-step explanation:

As, one integer will be "x"

The other will be even, so 2 digits after, so "x+2"

So, now (x) + (x+2) = 26

2x + 2 = 26

2x = 26 - 2

2x = 24

X = 24/2

X = 12

So, "x" = 12, so the first integer is 12

The next, as we said is "x+2", so it is 12+2 = 14

So the two integers are 12 and 14

Therefore, 12+14=26

for any of you who need the translation here it is

step-by-step explanation:

find the angular size of the equatorial radius of the earth, if the horizontal parallax of the sun

since the airplane is moving with constant speed then the distance travelled can be calculated by x=u*t

in km/h would be:

x=640*3.5=2.240 km

in m/s would be:

u=640 km/h= 640.000 m/h =640.000/ 3600 m/s =177.8 m/s

t= 3.5 h= 3.5 * 3600 s=12.600 s

then x=u*t= 177.8*12.600= 2.240.280 m
