Answer:

$VW=21\ units$

Step-by-step explanation:

we have that

Point W is between point V and point X

Points W,V and X are collinear

$VX=VW+WX$ -----> equation A (by addition segment postulate)

we know

$VX=(5x+1)\ units\\VW=(4x-7)\ units\\WX=3x\ units$

substitute the given values in the equation A and solve for x

$5x+1=(4x-7)+3x$

Combine like terms in the right sides

$5x+1=(7x-7)$

Group terms that contain the same variable

$7x-5x=1+7$

$2x=8$

$x=4$

<em>Find the length of VW</em>

$VW=(4x-7)\ units$

substitute the value of x

$VW=(4(4)-7)=21\ units$

In the morning, the temperature was 15∘F. During the day, the temperature fell 37 degrees. Which expression shows how to find th

tino4ka555 [31]

Answer:

- 22°F

Step-by-step explanation:

Given that :

Morning temperature = 15°F

Change in temperature = fall by 37 degree

The temperature of the end of the day:

Morning temperature + (change in temperature)

Fall by 37° = decrease in temperature by 37° = - 37°

15°F + (-37°F)

15°F - 37°F

= - 22°F

Mrs. Duncan measured the lengths of a crayon and a pencil. The pencil is double the length of the crayon. The sum of their lengt

Margarita [4]

Answer: The length of pencil is 16 centimetres and length of crayons is 8 centimetres

Step-by-step explanation:

Let the length of crayon = $x$

Length of a pencil = $2x$

As according to question that the sum of their length is 24 centimetres

So we have

$x+2x=24\\\\\Rightarrow 3x= 24 \\\\\Rightarrow x= \dfrac{24}{3} =8$

Therefore the length of crayon = 8 centimetres

Length of pencil= $2x= 2\times x = 2\times 8 =16$ centimetres

Hence, the length of pencil is 16 centimetres and length of crayons is 8 centimetres
