Janine and her older sister Ingrid's ages are consecutive even numbers. When Janine's age is divided by seven, and Ingrid's age
a_sh-v [17]

Answer:

Janine is 28. Ingrid is 30.

Step-by-step explanation:

Let the ages be x and x + 2 for Janine and her sister, respectively.

x/7 + (x + 2)/3 = 14

Multiply both sides by the LCD, 21, to get rid of denominators.

21 * x/7 + 21 * (x + 2)/2 = 21 * 14

3x + 7(x + 2) = 294

3x + 7x + 14 = 294

10x = 280

x = 28

x + 2 = 30

Answer: Janine is 28. Ingrid is 30.

What is the value of the product of -20/48 times 6 in simplified form
KATRIN_1 [288]
-20/48 x 6 =   \frac{-20}{48}    x  \frac{6}{1}

I would cancel out the 6 in the numerator and the 48 in the denominator 
Now I have <u />\frac{-20}{8}  or <u />\frac{-5}{2} reduced.

-5 ÷ 2  = -2 1/2 and that is the answer in simplest form

0.75 = 0.750<br> are they equal
Sliva [168]
Yes they are the same. The number on the right just has an extra zero. You can add an infinite amount of zeros to the end of a number without changing it's value.
