in the games they scored twice as many runs as their opponents they must have scored an even number of runs.
so in these games their opponents scored 1, 2 , 3 , 4 and 5 points.
total = 15 points.
in the other 5 games their opponents scored 1 more than the odd number scored by the team. that is 2, 4, 6, 8, 10 points.
total = 30 points.
total points scored by the opponents = 15 + 30 = 45 points (answer).
b) 4x+3y= -36
we rearrange a) as -x + y =2 and multiply it by 4
a) -4x + 4y = 8 then we add b)
b) 4x +3y = -36
7y = -28
y = -4
a) -4 = x +2
x = -6
for this case we have that the bread stick represents 1 unit.
then half of a loaf of bread will be given by:
if that half is cut into 4 equal parts we have:
thus, each part represents of the whole bread
