please help answer number 1

Answer:

x=-6/29

Step-by-step explanation:

Step 1: Simplify both sides of the equation.

5(3x+2)−2=2(1−7x)

(5)(3x)+(5)(2)+−2=(2)(1)+(2)(−7x)(Distribute)

15x+10+−2=2+−14x

(15x)+(10+−2)=−14x+2(Combine Like Terms)

15x+8=−14x+2

15x+8=−14x+2

Step 2: Add 14x to both sides.

15x+8+14x=−14x+2+14x

29x+8=2

Step 3: Subtract 8 from both sides.

29x+8−8=2−8

29x=−6

Step 4: Divide both sides by 29.

29x/29=-6/29

x=-6/29

Answer: 56.25%

Step-by-step explanation: You would divide 18 over 32, which would get the decimal 0.5625. Then you would multiply this by 100/100 which would get 56.25/100. This would get you 56.25%.

Answer: 5[tex]\sqrt{11}[/tex]

Step-by-step explanation:

25*11=275

[tex]\sqrt{25}\sqrt{11}[/tex]

25 is perfect square but 11 is not so 11 stays inside the radical while 25 is changed to 5

Answer:

I'm pretty sure it's 1, 2, and 3, but I'm not positive

I think the answer is for

1 book (x = 1)

1150+25(1)= 1175

For 2 books (x - 2)

1150+25(2) = 1200

Next, to find the change in total cost, subtract these 2 answers:

1200 - 1175 = 25

Answer:

Step-by-step explanation:

3 vegetarian pizzas cost 25.50. First we must find the cost of one vegetarian pizza.

25.5/3 = 8.5.

Each pizza costs $8.50. She bought 10 of them.

Now, we must multiply $8.50 by 10.

8.5x10 = 85.

$85 for all of the pizza.

Finally, subtract 85 from 100.

100-85=15.

You will receive $15 in change.

Answer:

Should be $15 change

Step-by-step explanation:

Since 3 pizzas cost 25.50 you times that by 3. Divide the 25.50 by 3 and add them two together. Take away that from the 100

The number of months that Zea can continue this pattern until she reaches her credit limit will be 27 months.

A credit card is a method of payment that is given to customers so they may pay a merchant for products and services depending on the debt they have accumulated.

Zea has a credit limit of $2,000 on her credit card. Each month, she charges about $200 and makes a payment of $125.

The distinction between the installment made and the charges done will be given as,

Difference = $200 - $125

Difference = $75

Partition as far as possible by this distinction to find the number of months that Zea can proceed with this example until she contacts her credit limit.

⇒ $2,000 / $75

⇒ 26.667 ≈ 27

The number of months that Zea can continue this pattern until she reaches her credit limit will be 27 months.

Answer:

Answers: (4. = 3) (5. = 9) (6. = 20)

You may need to input the number only without the "degrees".

=============================================================

Explanation:

First we'll focus on triangle DEH. Ignore the other points and values.

We have the sides of EH = 32 and DH = 49. Let x be the measure of angle DHE, which is one of the pieces of angle DHG. We'll use the cosine rule to find x.

cos(angle) = adjacent/hypotenuse

cos(H) = EH/DH

cos(x) = 32/49

x = arccos(32/49)

x = 49.227195

The value is approximate and rounded to 6 decimal places. Make sure your calculator is in degree mode. Arccos is the same as inverse cosine.

We'll come back to this value later.

---------------------

Now focus on triangle HFG. Ignore the other points.

We have the sides of FG = 38 and GH = 43

Let y be the measure of angle FHG, which is the missing piece to form angle DHG. Based on how x and y are set up, we can say x+y = angle DHG.

To find y, we'll need the sine rule this time

sin(angle) = opposite/hypotenuse

sin(H) = FG/GH

sin(y) = 38/43

y = arcsin(38/43)

y = 62.094527 which is approximate to 6 decimal places

---------------------

The last step is to add the values of x and y we found earlier

angle DHG = (angle DHE) + (angle FHG)

angle DHG = (x) + (y)

angle DHG = (49.227195) + (62.094527)

angle DHG = 111.321722

angle DHG = 111 degrees after rounding to the nearest whole degree.

----------------------

If you wanted to do this all in one step, you could say:

arccos(32/49)+arcsin(38/43) = 111.3217 which rounds to 111 degrees.

Answer:1 only solution

Step-by-step explanation:

If the discriminant is equal to 4, the number of solutions there are is; 2 solutions.

According to the question;

When the discriminant is a perfect square as in 4 above; Then the solutions to the equation are not only real, but also rational.

However, If the discriminant is positive but not a perfect square, then the solutions to the equation are real but irrational.
