2/3a - 2 = 1/3
2/3a = 2 + 1/3
2/3a = 7/3
a = (7/3) / (2/3)
a = (7/3) * (3/2)
a = 21/6
a = 7/2 ---- that is the answer
Hope this helps!
Answer: 13
Step-by-step explanation:
x = 5
-5 (5) + 12
-25 + 12
-13
abs(-13) = 13
To find absolute value, solve the equation as is and then make the answer positive.

Answer: speed of the car is 88 miles per hour
the speed of the motorcycle is 78 miles per hour
Step-by-step explanation:
Number of miles travelled by car = 312
Number of miles travelled by motorcycle = 272
Let x = speed of the car
Let y = speed of the motorcycle
If the car's speed is 10mph more than the motorcycle's, it means
x = y + 10 - - -- - - 1
Time taken for car to travel 312 miles is distance /speed = 312/x
Time taken for motorcycle to travel 272 miles is distance /speed = 272/y
The car travels 312 miles in the same time that a motorcycle traveled 272.
This means
312/x = 272/y
312y = 272x
y = 272x/312
Substituting y = 272x/312 into equation 1, it becomes
x = 272x/312 + 10
312x = 272x + 3120
312x-272x = 3120
40x = 3120
x = 3120/40 = 78 miles per hour
x = y + 10 = y + 78
x = 88 miles per hour
Answer:
En la última fila de la zona general hay 98 asientos y en la zona preferencial hay 564 asientos.
Explicación paso a paso:
= 1 + − 1 ×
40 = 20 + 40 − 1 × 2
40 = 20 + 39 × 2
40 = 20 + 78
40 = 98
= (1 + ) 2 ×
12= (36 + 58) 2 ×12
12 = 47 × 12
12 = 564
