Solve problem using substitution
2x + y = 10
y = x + 1

Answer:

y=10

x=10

Step-by-step explanation:

THis is isosceles triangle

180-90-45=45

used pyagorous therum thingy

10over2= square root of 200

so c2=asquare X b squared in this case x=y

so 200/2 = 100

x=100square

y=100 square

simplify = 10

Answer:

2490

Step-by-step explanation:

The 2 shapes are triangle and trapezoid

Area of a triangle formula: A= h×b/2

A=40×62/2

A=1240

Area of a trapezoid formula: base¹+base²/2×height

A= 38+62/2×25

A=1250

Add both areas together

1250+1240=2490

Answer:

x = 6

Step-by-step explanation:

(x + 2) + (2x + 3) = 23

Combine like terms

3x +5 = 23

Subtract 5 from each side

3x+5-5 = 23-5

3x = 18

Divide each side by 3

3x/3 = 18/3

x = 6

Answer:

x = 6

Step-by-step explanation:

1. Remove parentheses where unneeded. x + 2 + 2x + 3 = 23

2. Add constants. x + 5 + 2x = 23

3. Combine like terms. 3x + 5 = 23

4. Subtract "5" from the constants on both sides of the equation. 3x = 18

5. Divide both sides by 3. 3x/3 = 18/3

6. Simplify. x = 6

Step-by-step explanation:

Let 'x' be the original price.

x + 39% of x = 197.38

x + 0.39 x   = 197.38

1.39x  = 197.38

      x = 197.38/ 1.39

      x = 142

Answer and Step-by-step explanation:

Alot of these can be solved with the table up above the problems.

According to the table, every time a value has an exponent of 0, it would equal to 1. Since all A B and C values follow the 0 exponent, their value is 1.

According to the table, when we have a negative exponent, the number gets turned into a fraction of [tex]\frac{1}{x^x}[/tex]

Since our value is 9^-2, do as followed :

[tex]\frac{1}{9^2}[/tex]

Solve what is 9^2 :

[tex][\frac{1}{81} ][/tex]

[tex]\frac{1}{x^{-5} }[/tex]

This question is different, since we have to go backwards, we have to switch the negative exponent to a positive exponent and rid the fraction.

[tex]x^5[/tex]

[tex]5a^3b^{-2}[/tex]

Since we have one negative exponent, follow the fraction rule but instead of having one as the numerator, have 5a^3.

[tex]\frac{5a^3}{b^{2}}[/tex]

[tex]-3^4 = -3*-3*-3*-3=-81[/tex]

Since -3 is in parenthesis, we can rid the negative along with the parenthesis :

[tex](-3)^4=3^4=3*3*3=81[/tex]

Follow the negative exponent rule :

[tex](-3)^{-4}=\frac{1}{(-3)^4} =\frac{1}{3^4} =\frac{1}{3*3*3*3}= \frac{1}{81}[/tex]

Follow the negative exponent rule yet again :

[tex]-3^{-4}=-\frac{1}{3^4} =-\frac{1}{3*3*3*3} =-\frac{1}{81}[/tex]

Answer and Step-by-step explanation:

Let x be for mimstoons, and y be for naxvips.

The equations would be:

x + y = 60

1x + 4y = 60

x is for the amount of mimstones, while y is for the amount of naxvips, and when we add these together, we get the 60 amount of both the items combined.

With the second equation, we multiply the amount that was bought times the price to get the total price of $60.

Answer:

sorry no can do

Step-by-step explanation:

hehhehehehehehhehe

Answer:

y = -2x +20

6x - 5y = 12

Put the value of y in 2nd equation

6x - 5( -2x +20 ) = 12

6x +10x -40 = 12

16x = 12 +40

16x = 52

x = 13/4

Putting the value of x in equation 1

y = -2x +20

y = -2(13/4 ) +20

y = 27/2

Answer:

x = 7

angle (7x + 8) = 57 degrees

Step-by-step explanation:

all triangles interior angles add up to 180 degrees.

(7x+8) + 90 + 33 = 180

7x+8 = 57

7x = 49

x = 7

(7x + 8) = 57

Answer:

57 degrees

Step-by-step explanation:

7x+8+33=90

7x=90-8-33

=90-41

7x=49

x=7

Answer:

p=-2

Step-by-step explanation:

Start off by adding 3 to both sides:

-6p-3=9

    +3 +3

Now you have this:

-6p=12

Now divide both sides by -6

-6p/-6=12/-6

p=-2

I hope this helps, and have a great day! <3 :)

Answer

-6p - 3 = 9

     + 3 + 3

-6p = 12

 6      6

p = -2

Step-by-step explanation:

BigBytes will be 100 +10x = y ($100 flat fee plus 10 times the number of gigabytes equals total cost).

GoGig will be 120 + 5x = y.  ($120 flat fee plus 5 times the number of gigabytes equals total cost).

Now set them equal to each other and solve for x to find where the gigabytes are the same.

100 + 10x = 120 + 5x

Subtract 100 from both sides:  10x = 20 + 5x

Subtract 5x from both sides:  5x = 20.

Divide both sides by 5:  x = 4.  4 gigabytes is the answer.

a brainliest would be appreciated :)

The total amount you will pay for phone service is 4 gigabytes.

An equation is an expression that shows the relationship between two or more numbers and variables.

BigBytes will be 100 +10x = y

Therefore , We have $100 flat fee plus 10 times the number of gigabytes equals total cost).

GoGig will be 120 + 5x = y.  

We have $120 flat fee plus 5 times the number of gigabytes equals total cost).

Now set them equal to each other and solve for x;

100 + 10x = 120 + 5x

Now Subtract 100 from both sides:  

10x = 20 + 5x

Then Subtract 5x from both sides:

5x = 20.

Now Divide both sides by 5:  

x = 4.  

Hence, the total amount you will pay for phone service is 4 gigabytes.

Answer:

2.3

Step-by-step explanation:

First off, you start with the circumference formula which is 2(pi)r. Since we know our circumference, we can create the equation solving for r. so we have 15=2(pi)r. Now in order to solve for r, we need to transfer everything to the other side, meaning dividing by 2(pi). So 15/2(pi)=2(pi)r/2(pi). Since we are using 3.14 for pi, 3.14*2 is 6.28. 15/6.28 which is about 2.388 So the radius of the circle is 2.3 (rounded to the nearest tenth)
