Answer:
(x, y) = (10, - 1)
Step-by-step explanation:
given the 2 equations
3y = -
x + 2 → (1)
y = - x + 9 → (2)
substitute y = - x + 9 into (1)
3(- x + 9) = -
x + 2
- 3x + 27 = -
x + 2
add
x to both sides
-
x + 27 = 2 ( subtract 27 from both sides )
-
x = - 25
multiply both sides by 2 and divide by - 5
x = 10
solution (10, - 1)
Answer:
10cm, 16 cm, 18 cm
Step-by-step explanation:
We have to find the sum of proportion: sum of ratios =
a : b : c = 5:8:9
Sum of proportion = 5 + 8 + 9
= 22
Length of side a
5/22 × 44 = 10 cm
Length of side b
8/22 × 44 = 16 cm
Length of side a
9/22 × 44 = 18 cm
Therefore: lengths of the sides of the triangle in cm are
10cm, 16 cm, 18 cm
