Answer 1

Answer:

[tex]x = - 3[/tex]

[tex]y = - 2[/tex]

Step-by-step explanation:

Since y=x+1 plug it into bottom equation as y.

[tex]x + 1= 5x + 13[/tex]

Subtract 1 from both sides

[tex]x = 5x + 12[/tex]

Subtract 5x from both sides

[tex] - 4x = 12[/tex]

Divide both sides by -4

[tex]x = - 3[/tex]

Now x=-3 into the top equation to find y

[tex] - 3 + 1 = - 2[/tex]

y=-2

3) 10+3n=20+5n Set up the problem

        -3n       -3n Subtract 3n from both sides to get n on one side of the equation.

    10     =20-2n

    -20     -20 Subtract 20 from both sides to isolate n

     -10    =2n

      /2       /2 Divide both sides by 2 to isolate n

      -5    =   n

4) 18=2(b+6) Write down problem

   18=2b+12 Distribute

    -12     -12 Subtract 12 from both sides to isolate b

    6=2b

     /2/2 Divide both sides by 2 to isolate b

     3=b

Answer:

3) 3x+10 = 5x+20

=> 3x-5x= 20-10

=> -2x= 10

=> x = 10/-2

=> x= -5

4) 2(b+6) = 18

=> 2b +12 = 18

=> 2b = 18-12

=> b= 6/2

=> b = 3

A cylinder has a height of 15 cm and a radius of 8 cm.
What is its volume, to the nearest cubic centimeter?
Be sure to include your calculations in your explanation.

Answers

First you need to find the area of the circle (the bottom of the cylinder):

8*8*3.14 = 200.96 cm^2

Then to find the volume of the cylinder, multiply the area of the circle by the height of the cylinder which in this case is 15 cm:

200.96*15= 3,014.4 cm^3

Which can just be rounded to 3,014 cm^3 (nearest whole number)

PLEASE HELP IM BEGGING

Answers

Answer:

its 16

Step-by-step explanation:

area for a triangle is 1/2 the base times the height.

IN order to find out the base you need to multiply the area by two and then divide by 42 to find the base. X will represent the base

so

336 *2 = 42x

672= 42x

672/42=x

Answer:

5) First you have to find x, then use it with supplementary angles theorem.

6) STQ = 150˚

Step-by-step explanation:

To find x, add (2x+8), (71-x), and 90˚ together to add up to 180˚ (those three angles are supplementary):

(2x+8) + (71-x) + 90 = 180˚

x + 169 = 180

Then solve for x:

x = 11

You can check if x is right by inputing it back into the two equations and see if all three of the angle measures together equal 180˚.

Now, you only need m∠MTS (2x+8) to find m∠STQ...

m∠MTS + m∠STQ = 180˚ because they are supplementary angles.

Input the found x to find m∠MTS:

(2(11)+8) = 30

Subtract 30 from 180 to find m∠STQ:

180 - 30 = 150

m∠STQ = 150˚

Hope this helped :)
