Answer:
x = 6
Step-by-step explanation:
Given
2x - 5 = 7 ( add 5 to both sides )
2x = 12 ( divide both sides by 2 )
x = 6
Answer: (5^3) / (5^7) = 5^ -4
or
1 / 5^4
Step-by-step explanation:
Answer: $80
Step-by-step explanation:
Given: The amount earned by Fadil on selling 14 televisions= $1400
Therefore, the amount he earned on selling 1 television=
Since, he sold televisions with extended warranty and he earns $20 additional for it.
Then, the fixed amount Fadil earns for each television=
Hence, Fadil earns $80 as the fixed amount for each televison.
Note: 1 inch = 2.54 cm is an exact converion, while 1 mile=1.6km is only approximate.
Using conversion
1 inch=2.54 cm
1 mile = 1760*3*12 = 63360 in = 160934.4 cm
If 1 inch = 1 mile, then
2.54 cm : 1 mile = 1.609344 km
1 cm : 0.6336 km (exactly), or
1 cm : 0.6 km (approximately)
Using both conversions:
1 inch = 2.54 cm : 1 mile = 1.6 km
=>
2.54 cm : 1.6 km
1 cm : 1.6/2.54=0.6299 km (approximately), or
1 cm : 0.6 km (approximately)
The large angle = 120 degrees
Supplementary angles are two angles whose measures add up to 180°
Since we know from the ratio that one angle is twice the size of the other, the angles have to be 60 and 120.
