Answer:
1 ft 9 in
Step-by-step explanation:
To find the length of the flag, we simply need to add the fractions. Because all the lengths have the same denominator, we only need to add the numerators.
5 + 3 + 6 = 14. The flag is 14/8 feet long.
To simplify this, divide 14 ÷ 8 = 1.75
This means the flag is 1 foot and 9 inches.
Answer:
Step-by-step explanation:
4) Given that 3x<15
Divide by +3 without affecting inequality
x<5
Hence answer is (-∞,5)
5) -6x<18
Add 6x to both sides
0<6x+18
Subtract 18
-18<6x
Divide by +6
-3<x
Hence answer is (-3,∞)
6) 2x+6>x-7
Subtract x-6 from both the sides
x >-13
So answer is (-13,∞)
7) -4x+8≥14
Add 4x-14 to both the sides
-6≥4x
x≥-3/2
Hence answer is [-3/2,∞)
