step 1 subtract 5 from each side

2x=22

step 2 divide each side by 2

x=11

Answer:

2x=27-5

2x=22

2x/2=22/2

x=11

Answer:

60 divided by -12 = -5

Answer:

Step-by-step explanation:

Subtract equation 2 from equation 1

.7x+y-(-1.5x+y)=340-320

.7x+y+1.5x-y=20

2.2x=20

x=100/11, then use this in either original equation to find y.

.7(100/11)+y=340

y=3670/11, so the balance point is

(100/11, 3670/11)

Answer:

2/3x-y=-4

Step-by-step explanation:

Answer:

AAA (or AA)

Step-by-step explanation:

Prove ΔBEC ~ ΔDEA

(using three angles is unnecessary because you can just use Angle Angle to prove similarity)

First, m∠BCE = m∠EAD because of alternate interior angles.

Then, m∠ADE = m∠CBE  because of alternate interior angles.

m∠BEC = m∠AED because of vertical angles

Thus, ΔBEC ~ ΔDEA because of Angle Angle Angle [AAA] (or AA if you only chose to use 2 angles)

The shape that can be rotated to create a sphere is the circle (option C).

A sphere is a three-dimensional object with all points equidistant from its center. When a circle is rotated about its center axis, it creates a three-dimensional shape that perfectly matches the definition of a sphere.

Let's consider the other options and why they cannot be rotated to form a sphere:

A. Triangle: A triangle is a two-dimensional shape with straight sides. Rotating a triangle around any axis would not result in a three-dimensional shape with all points equidistant from its center, which is the defining characteristic of a sphere.

B. Square: Similarly, a square is a two-dimensional shape with straight sides. Rotating a square around any axis would not create a sphere, as it would still retain its flat, planar nature.

D. Ellipse: An ellipse is a two-dimensional shape resembling a squashed or stretched circle. Rotating an ellipse would not result in a sphere, as it would still retain its elliptical shape.

Therefore, the shape that can be rotated to create a sphere is the circle (option C) due to its symmetrical and curved nature.

Answer:

1,330.5 cm³

Step-by-step explanation:

Volume of cylinder = πr²h

Where,

r = ½ of 11 = 5.5

h = 14 cm

Plug in the values

Volume = π × 5.5² × 14

Volume = π × 423.5

Volume = 1,330.5 cm³ (1 d.p)

Answer:

  C)  800%

Step-by-step explanation:

The markup amount is the difference between the selling price and the cost:

  markup = selling price - cost

  markup = $63 -7 = $56

The percentage markup relative to the cost is ...

  markup/cost × 100%

  = ($56)/($7) × 100%

  = 8×100% = 800%

Answer:

y=35x+60

slope-35 y intercept-60

proportional relationship

Step-by-step explanation:

Answer:

Step-by-step explanation:

y = 35x + 60

Slobe 35

y-intercept 60

The y-intercept is the start cost and the slope is how much it will go up per hour.

It is proportional because it is going up by 35 every hour

w

3w+2=29(Multiply both sides by w)

3w2+2w=29w(Multiply both sides by w)

3w2+2w−29w=29w−29w(Subtract 29w from both sides)3w2−27w=0

3w(w−9)=0(Factor left side of equation)

3w=0 or w−9=0(Set factors equal to 0)

w=0 or w=9

Check possible critical points.

Step-by-step explanation:

3(x + 3y + 2x - y)

= 3 (x + 2x) + (3y - y)

= 3 (3x + 2y)

= (3 • 3x) + ( 3 • 2y)

Answer:

y = 2

Step-by-step explanation:

m = (2 - 2)/(6 - (-6))

m = 0

there's no slope, so it's just 2

As you can see the 2 points have the same y coordinate that means the line passing through it is going to be a horizontal line with a consistent y level of -2.

The equation will be just what I said y=2

Answer:

x=5 cm,y=12 cm

Step-by-step explanation:

We are given that

RQ=3 m

PQ=4 cm

RP=x cm

RS=13 cm

SP=y cm

We know that Pythagoras theorem

[tex](Hypotenuse)^3=(base)^2+(perpendicular\;side)^2[/tex]

In right triangle RQP

Using Pythagoras theorem

[tex]RP^2=RQ^2+PQ^2[/tex]

Substitute the values

[tex]x^2=3^2+4^2[/tex]

[tex]x^2=9+16[/tex]

[tex]x^2=25[/tex]

[tex]x=\sqrt{25}=5[/tex]cm

Now,

In triangle RPS

[tex]RS^2=RP^2+SP^2[/tex]

[tex](13)^2=5^2+y^2[/tex]

[tex]169=25+y^2[/tex]

[tex]169-25=y^2[/tex]

[tex]144=y^2[/tex]

[tex]y=\sqrt{144}=12[/tex] cm
