280 because 35 in 15 min. and 15min. times 4 is one hour, so for two hours it would be times 8, 8 times 35 equals 280
Answer:
<h3> No such four numbers</h3>
Step-by-step explanation:
x - the first number
x+1 - the number consecutive to x (secon consecutive)
x+1+1=x+2 - next consecutive number (the third)
x+2+1 = x+3 - the last consecutive number (fourth)
x + x+1 x+2 + x+3 = 180
4x + 6 = 180
-6 -6
4x = 174
÷4 ÷4
x = 43.5
It is not an integer. I means there are not four consecutive integers which gives the sum 180.
It's +31.
if there's a minus next to a bracket you have to turn every operator the opposite inside that bracket
-(-31) = +31
