Answer:
Step-by-step explanation:
1). (10x - 27)° = (2x + 29)°
10x - 27 = 2x + 29
8x = 56
x = 7
<em>m∠W</em> = (2(7) + 29)° <em>= 43°</em>
2). (14x + 4)° + 51° + 55° = 180°
14x + 110 = 180
<em>x = 14</em>
Answer:
they are alike because they both are to the 5th power and they are different because one is positive and one is negative
Step-by-step explanation:
R = Rate of gasoline by automobile = 35 mi/gal
it is given that , 1 kilometer = 0.6214 miles
and 1 gallon = 3.78 liter
so
R = 35 (miles/gallon) (1 kilometer/0.6214 miles) (1 gallon/3.78 liter)
R = (35) (1/0.6214) (1/3.78) (miles x 1 kilometer/1 miles) (1 gallon/(1 gallon x 1 liter))
R = 14.9 kilometer/liter
Answer:
C
Step-by-step explanation:
5.1 + 2y + 1.2 = -2 + 2y + 8.3 ( subtract 2y on each side)
5.1 + 1.2 = -2 + 8.3 ( collect like terms)
6.3 = 6.3
If the equation ends with a true statement (ex: 2=2) then you know that there's infinitely many solutions or all real numbers.
4/6 is the same as 2/3 so
5/6 - 4/6 = 1/6
