Answer:

  D.  5/6

Step-by-step explanation:

The given fractions have decimal values of ...

  2/3 ≈ 0.67

  6/7 ≈ 0.86

The answer choices are approximately 0.60, 0.50, 0.43, and 0.83.

The last choice (5/6) is between 2/3 and 6/7.

Using a common denominator of 42, these three fractions are ...

  2/3 = 28/42

  5/6 = 35/42

  6/7 = 36/42

The fraction 5/6 lies between 2/3 and 6/7.

_____

It is useful to memorize the decimal equivalents of fractions with denominators of 10 or less. There are some patterns involved that make it easier.

Alvin is 8 years older than Elga. The sum of their ages is 78. What is Elga's age?
Mazyrski [523]

Answer:

35

Step-by-step explanation:

ok let's look at these old farts.

alvin is 8 years older than elga, so elga needs 8 more years to be as old as Alvin is. AKA,

Alvin = Elga + 8

The sum of their ages is 78.

Alvin + Elga = 78

Now put the equations together,

(Elga + 8) + Elga = 78

2 * Elga = 70

Elga = 35

Therefore, Elga is 35 years old! So old !!

Solve the equation <br> -10 + 3x + 5x = -56 ? ??
Xelga [282]
Add like terms on the same side:
-10 + 8x = -56
Add ten to both sides
-10 + 8x + 10 = -56 +10
Simplify:
8x = -46
Divide both side by 8
8x/8 = -46/8
Simplify
x = - 5.75
The answer is x = -5.75
(The answer can also be written as -23/4 or -5 3/4)

Answer:

x = 18

y = 54

Step-by-step explanation:

A straight line equals 180 degrees.

Since Lines CD and AB are straight, we can deduce that the angle 3x = 2x + angle AN.

Because there is a right angle, we can subtract 90 -72 = 18.

18 + 2x = 3x

18 = x

A straight line equals 180 degrees. Once we figure out that x = 18, we can figure out y by plugging in x and then subtracting your answer from 180 degrees.
