Answer:
58 and 42.
Step-by-step explanation:
Let the 2 numbers be x and 100-x.
Also let x be the largest number, so
x ≥ 100 - x + 16 ( 'At least 16' means equal to 16 or greater than 16).
Add in x to both sides:
x + x ≥ 100 + 16
2x ≥ 116
x ≥ 58.
But since the sum of the 2 numbers is 100, x must be 58 and the other number is 42.
[ ISN} and {TSW} so the answer is D
Answer:
n = 16, AC = 60, DE = 30
Step-by-step explanation:
DE joins the midpoints of 2 sides of the triangle and is half the length of the third side, that is
DE = 
AC , substitute values
n + 14 = (3n + 12) ← multiply both sides by 2 to clear the fraction
2n + 28 = 3n + 12 ( subtract 2n from both sides )
28 = n + 12 ( subtract 12 from both sides )
16 = n
Then
AC = 3n + 12 = 3(16) + 12 = 48 + 12 = 60
DE = n + 14 = 16 + 14 = 30
Answer:
r= d/2
7/2
3.5
3.5 is the answer
Step-by-step explanation:
here's the solution,
first equation,
=》3x + y = 11
=》y = 11 - 3x
now, in second equation,
=》2x - y = 4
plugging the value of y as 11 - 3x,
=》2x - (11 - 3x) = 4
=》2x - 11 + 3x = 4
=》5x = 11 + 4
=》x = 15 ÷ 5
=》x = 3
now, plugging the value of x as 3 in equation 1
=》3x + y = 11
=》3 × 3 + y = 11
=》9 + y = 11
=》y = 2
