zimovet [89]

Answer:

-7/8

Step-by-step explanation:

If two lines are parallel, they have the same slope. The slope of p is -7/8 (y=mx+b), so the slope of q is also -7/8.

18 2/5 - n = -10 1/3
Wewaii [24]

Answer:

The answer is n=28\frac{11}{15}.

Step-by-step explanation:

Given:

18 2/5 - n = -10 1/3.

Now, to solve the equation:

18\frac{2}{5} - n = -10 \frac{1}{3}

Converting the mixed fractions to improper:

⇒\frac{92}{5} -n=-\frac{31}{3}

Moving the numbers on one side and variable to the other:

⇒\frac{92}{5} +\frac{31}{3}=n

Now, solving the factions:

⇒\frac{92\times 3+31\times 5}{15}=n

⇒\frac{276+155}{15}=n

⇒\frac{431}{15}=n

⇒28\frac{11}{15}=n

Therefore, the answer is n=28\frac{11}{15}.

Linda is 12 years younger than her sister Laura. Together their total age is 18. How old is Linda? How old is Laura?
geniusboy [140]

Answer:

Linda: 3 ; Laura: 15

Step-by-step explanation:

Note that Linda + Laura's age is 18, and that Linda is 12 years younger than her sister.

Let "Linda" = x , "Laura" = y:

x + y = 18

x = y - 12

First, plug in y - 12 for x in the first equation:

(y - 12) + y = 18

Simplify.

2y - 12 = 18

Isolate the variable (y). Note the equal sign, what you do to one side, you do to the other. Do the opposite of PEMDAS. First add, then divide.

2y - 12 (+12) = 18 (+12)

2y = 18 + 12

2y = 30

(2y)/2 = (30)/2

y = 30/2

y = 15

Next, plug in 15 for y in the second equation (the other equation would work too).

x = y - 12

x = (15) - 12

x = 3

Linda's age is 3, Laura's age is 15.
