Y = -10 and x = -13 (substitute 2y + 7 for x)
2+1=3
15/3=5
split the 3 5's in ratio 2:1 and you get 10:5
Answer:
The perimeter of the triangle can be expressed as 5x + 18.
Step-by-step explanation:
Perimeter of an object is the sum of the length of its sides.
For the required triangle, we have;
length of the base = x
length of the second side = 3x + 9
length of the third side = x + 9
Perimeter of the triangle = length of the base + length of the second side + length of the third side
= x + (3x + 9) + (x + 9)
= x + 3x + 9 + x + 9
= 5x + 18
The perimeter of the triangle can be expressed as 5x + 18.
Answer:
7.3
Step-by-step explanation:
time is distance divided by velocity/speed
t = 220/30
t = 7.33333 = 7.3
87654210 is the largest number
