3 − 1 = 5 + 10 = −5 1/2 Check whether the given value of is a solution to the equation. Justify your answer.

andrey2020 [161]

Answer:

$x = -5\frac{1}{2}$ is the solution

Step-by-step explanation:

Given

$3x - 1 = 5x + 10$ --- Correct expression

$x = -5\frac{1}{2}$

Required

Determine if the given solution is correct

To do this, we simply solve for x in the given equation.

So, we have:

$3x - 1 = 5x + 10$

Collect like terms

$3x - 5x = 1 + 10$

$-2x = 11$

Divide both sides by -2

$\frac{-2x}{-2} = \frac{11}{-2}$

$x = -\frac{11}{2}$

$x = -5\frac{1}{2}$

From given picture we can see that X is mid point of line PQ

So PQ=2PX

From given picture we can see that Y is mid point of line PR

So PR=2PY

Now consider triangles PRQ and PYX

Sides PQ and PX has same ratio as of sides PR and PY (as calculated above)

angle XPY= angle QPR (common angle)

Hence triangles PRQ and PYX are similar.

We know that ratio of the sides of similar triangles is always equal so we can write:

$\frac{PQ}{PX} = \frac{QR}{XY}$

Plug the given values QR=8 and PQ=2PX

$\frac{2PX}{PX} = \frac{8}{XY}$

$\frac{2}{1} = \frac{8}{XY}$

$2 = \frac{8}{XY}$

$XY = \frac{8}{2}$

$XY = 4$

Hence final answer is XY = 4 units.

Radda [10]

Answer:

The answer is D. $618,750.

Step-by-step explanation:

20,000 x 17.50 = 350,000.

25,000 x 10.75 = 268,750.

350,000 + 268,750 = 618,750.

Catie used 68 beads on 17 in of wire. She used 7 in of wire for one bracelet. Predict the number of beads she used on 7 in of wi

Vikentia [17]

Catie used 28 beads on the 7 in. wire because when you divide 68÷17 you get 4 which means that she used 4 beads every 1 in. Then you multiply 4×7 because that's how much we need to figure out and you get 28.
