Answer:
f(-3) = 6
Step-by-step explanation:
We know that the sum of all angles in any triangle is always 180 and we know that:
The smallest angle = x
Angle 2 = x + 35
Angle 3 = 3 * x
So:
180 = x + x + 35 + 3 * x
180 = x + x + 35 + 3x
180 = 2x + 35 + 3x
180 = 5x + 35 / - 35 (both sides)
145 = 5x / ÷ 5 (both sides)
x = 29
The smallest angle = 29
Angle 2 = 29 + 35 = 64
Angle 3 = 3 * 29 = 87
Check:
29 + 64 + 87 = 180, so it's correct :)
1) let's find the numbers of students that travel by bus
262-7 = 255, as were used 5 bus lets divide 255/ 5 = 51, it means that 51 studens by bus
Answer:
2(n + 3) - 6 is the expression that represents the final number.
Step-by-step explanation:
-Given the number Lonnie thinks of at the beginning is 'n'-
1) adding 3 to n
sum = n + 3
2) multiply the sum by 2
sum = 2(n + 3)
3) subtract 6
sum = 2(n + 3) - 6.
