Calculator estimates 4/13 is .3076 and 3/10 to be .3 so 4/13 is larger
3/10 is rational because decimal can be predicted unlike 4/13 which keeps going
Plural because it has eaten
10 2/3 - (-3/4)
= 10 2/3 + 3/4 You make the denominator on each side the same in order to add them together
= 10 8/12 + 9/12
= 10 17/12
= 11 5/12
Answer:
13 and 44
Step-by-step explanation:
let x and y be the 2 numbers with y < x , then
x - y = 31 ( add y to both sides )
x = y + 31 ( subtract 31 from both sides )
x - 31 = y → (1)
4y = x + 8 → (2)
substitute y = x - 31 into (2)
4(x - 31) = x + 8
4x - 124 = x + 8 ( subtract x from both sides )
3x - 124 = 8 ( add 124 to both sides )
3x = 132 ( divide both sides by 3 )
x = 44
substitute x = 44 into (1)
44 - 31 = y , then
y = 13
the 2 numbers are 13 and 44
1) exterior angle = sum of interior angles except the neighboring one.
1) 48 + 45 = 93
2)180 - 147 = 33 , 180 - 72 = 108
x = 180 - 108 - 33 = 39
3) 180 - 104= 76
x = 51 + 76 = 127
4) 180 -154 = 26 , 180 - 73= 107
x = 180 - 107 - 26= 47
180 - 110 = 70
x = 180 - 140 = 40
last) 180 - 122 = 58
x = (180 - 58)/2 = 61
