Answer:

x=5

Step-by-step explanation:

That is your answer .

First you do 4x-3+3=2x+7+3

then,4x=2x+10,then

subtract 2x from both side

4x-2x=2x+10-2x

simplify

2x=10

divide both sides by 2 2x/2=10/2

simplfy and you get x=5

Hope this helps :)

Seamstress Jane has purchased 50 yards of red fabric and 110 yards of gold fabric to make red and gold curtains. What is the lar
Alisiya [41]

Answer: There are 10 largest number of curtains she can make if she wants all the curtains to be exactly the same length.

There are 5 red fabrics and 11 gold fabrics that would be used for each curtain.

Step-by-step explanation:

Since we have given that

Number of yards of red fabric purchased by Jane = 50

Number of yards of gold fabric purchased by Jane = 110

We need to find the largest number of curtains she can make if she wants all the curtains to be exactly the same length.

For this we will find H.C.F. of 50 and 110.

Factors of 50 = 1, 2, 5, 10, 25, 50.

Factors of 110 = 1, 2, 5, 10, 11, 22, 55, 110.

So, Highest common factor of 50 and 110 is 10.

So, there are 10 largest number of curtains she can make if she wants all the curtains to be exactly the same length.

Number of yards of red fabric is given by

\frac{50}{10}=5

Number of yards of gold fabric is given by

\frac{110}{10}=11

Hence, there are 5 red fabrics and 11 gold fabrics that would be used for each curtain.

Select the correct answer.
makvit [3.9K]

Answer:

<h3>64°</h3>

Step-by-step explanation:

y = 52° ( Opposite Angles )

y + 2x = 180° ( Interior Angles )

y + 2x =  {180}^{o}  \\  {52}^{o}  + 2x =  {180}^{o}  \\ 2x =  {180}^{o}  -  {52}^{o}  \\ 2x =  {128}^{o}  \\ x =  \frac{ {128}^{o} }{2} \\ x =  {64}^{o}  \\

crimeas [40]

Using the slope concept, it is found that:

  • The minimum horizontal distance is of 14,281.5 feet.
  • The maximum horizontal distance is of 15,398.6 feet.

<h3>What is a slope?</h3>
  • The slope is given by the <u>vertical change divided by the horizontal change</u>.
  • It's also the tangent of the angle of depression.

In this problem, the vertical change is the altitude of 10,000 feet.

The minimum horizontal distance is with an angle of 35º, hence:

\tan{35^{\circ}} = \frac{10000}{d}

d = \frac{10000}{\tan{35^{\circ}}}

d = 14281.5

The maximum horizontal distance is with an angle of 33º, hence:

\tan{33^{\circ}} = \frac{10000}{d}

d = \frac{10000}{\tan{33^{\circ}}}

d = 15398.6

Fill in the blank. ​A(n) _______ distribution has a​ "bell" shape. ​A(n) ▼ outlier polygon normal relative frequency distributio
EastWind [94]

Answer:

Normal Distribution

Step-by-step explanation: A normal distribution will generally have a bell shape. It is also called a bell curve, due to its bell shape.

It is also called Gaussian distribution. The point near the peak is where most of the observations cluster, while the values further away from the mean will be distributed equally in both directions on the curve.
