What is the result of adding these two equations?\begin{aligned} -5x-9y &= 3 \\\\ 5x-9y &= -2 \end{aligned} −5x−9y5x−9y =3=−2

A woman 38 years old has a daughter 14 years old. How many years ago was the woman 8 times older than the daughter?

The temperature was -5 F when shelly went to school on Monday. the temperature rose 20 F during the day but fell 25 F during the night. A heat wave increased the temperature 40 F on Tuesday but then an arctic wind overnight decreased the temperature 70 F.What was the temperature on Wednesday

Zoey invested $230 in an account paying an interest rate of 6.3% compounded daily.Assuming no deposits or withdrawals are made, how much money, to the nearesthundred dollars, would be in the account after 12 years?

Explanation:

We have two workers, more or less. Worker A gets the job done in 5 hours. Worker B comes along to help. If A and B work together, they get the job done in 4 hours. This assumes neither worker hinders the other.

Worker A's rate is 1/5 of a job per hour. In other words, after 1 hour, 1/5 of the job is done.

The combined rate is 1/4 for similar reasoning

Worker B's rate is 1/x where x represents how long it takes worker B to get the job done on its own.

The equation to solve is

1/5 + 1/x = 1/4

Note how 1/5 and 1/x represents the sum of the individual rates to get the combined rate 1/4

To solve this equation, it helps to clear out the fractions. Multiply every term by the LCD 20x

20x(1/5 + 1/x) = 20x(1/4)

20x(1/5) + 20x(1/x) = 20x(1/4)

4x + 20 = 5x

From here you can probably see solving this is relatively easy

4x+20 = 5x

20 = 5x-4x

20 = x

**x = 20**

Therefore, it will take **20 hours** for worker B to get the job done on its own.

Going back to the processing context, it takes **20 hours** for the new processor to download the movie. This is where the new processor is working alone without help from the original processor.

Side note: downloading a movie really depends on internet speed rather than processor speed.

The question is missing parts. Here is the complete question.

Quadrilateral PQRS (shown below) is an isosceles trapezoid. If RP = 12, then SQ = ?

**Answer:** SQ = 12

**Step-by-step explanation:** A trapezoid is a quadrilateral with two opposite parallel sides, called bases. The trapezoid is an ** isosceles trapezoid** when the non-parallel sides have the same length.

One property of isosceles trapezoid is that its diagonals are congruent, i.e., have the same length.

In the picture, segment RP is one of the trapezoid's diagonal. It is asking the measure of SQ, which is the other diagonal. So:

SQ = RP

SQ = 12

__Segment SQ of isosceles trapezoid PQRS is ____12 units____.__

**Answer:**

if quadrilateral PQRS is an isosceles trapezoid if RP=12 then SQ= 12

**Step-by-step explanation:**

Answer:

Ashley= 15

Milan= 11

Carlos= 105

Step-by-step explanation:

Let, A, M and C denotes Ashley, Milan and Carlos respectively.

A+M+C= 131 (according to the question)

Here,

C= 7A

A= M+ 4

So, M= A - 4

Now,

A+M+C = 131

or, A+ A-4+ 7A = 131 (putting the values)

or, 9A - 4 = 131 (adding like terms i.e. A + A + 7A)

or, 9A = 131 + 4

or, 9A = 135

or, A = 135 / 9

So, A = 15

C= 7A = 7×15= 105

M= A-4 = 15 - 4 = 11
