Find the missing coordinate to complete the ordered-pair solution to the given linear equation:

A) y+6x=5 

(a) (-1,?)

      (b) (3,?) 

B) 3x+2y=-6 
      (a) (-2,?)

      (b) (?,3) 

C) 2x+1/3y=5 
      (a) (?,18)

      (b) (8/3,?)

Answers

A
a) y+6x=5 if x= -1  then y+6(-1)=5 then y = 11
b) same thing if x = 3 then y+6(3)=5 y+18=5  subtract both sides by -18 and leave y on left then add 5+(-18)= 13 then y=13

B same as above
question (a) asks you to solve for y because x is -2
(b) asks you to solve for x because y is known
3x+2y=-6 if y = 3 you write 3x+2(3)=-6 3x+6=-6 move the +6 over to right side by subtracting 6 from both side 3x=-6 + -6 so 3x=-12 to get rid of the 3 and only leave the x you want to divide both side by 3 then x= -12/3 then the answer would be x=-4

A cylinder has a height of 5 meters and a diameter that is 4 times the measure of the height. Using 3.14 for pi, which of the following can be used to calculate the volume?

Answers

The volume of the cylinder 1,570 square meter. This is calculated using the formula volume is equal to height times Pi times radius squared. We first solve the radius which is 5 meters times 4 equals to 20 meters, this is the diameter of cylinder. But we need the radius, so 20 meters divided by 2 is equals to 10. Then substituting the given figure to the formula,  Volume = 5 (3.14) (10), it will give us 1,570 square meter.

If two angles are both vertical and supplementary, then the angles are

Answers

we know that

Supplementary angles are those angles whose sum is equal to 180 degrees and vertical angles are angles that are congruent.

so

Let

x--------> the first angle

y--------> the second angle

so

x=y --------> equation 1

x+y=180 --------> equation 2

Substitute equation 1 in equation 2

x+[x]=180

2x=180

x=90

y=90

therefore

the answer is

the angles are right angles
ur answer would be RIGHT angle!!!

Hope its right! 

If one gallon is the same amount as 16 cups, how many cups equal 2.5 gallons? (Only input whole numbers.)

Answers

Answer:

40

Step-by-step explanation:

Hello, I think I can help you with this

you can solve this easily using a simple rule of three

Step one

define the relation and solve for x

if

1 gallon ⇒16 cups

2.5 gallons⇒x cups?

(1)/(16) = (2.5)/(x) \nisolate\ x\n(1*x)/(16)=2.5\nx=(2.5*16)/(1) \nx=40

so, 2.5 gallons is the same amount as 40 cups

I hope it helps, Have a fantastic  day.
40 cups, 16+16=32, 32+1/2 16=40, 16÷2=8:) hope i helped
