which of these steps will eliminate a variable in this system? help pls

Answer:

x= 3

Step-by-step explanation:

12x-12x= 2x 1+5=6

2x=6

x=3

Answer: x=3

Step-by-step explanation:

(10x+1)=(12x-5) (you make them equal because they are vertical)

-2x+1=-5

-2x=-6

x=3

I'm not really sure but I tried, sorry.

Answer:

6 laps

Step-by-step explanation:

Each lap Jeffrey needs to run is one tenth of a mile he wants to run threee fifths of a mile how many laps does he need to run

One tenth of a mile = 1/0

Three fifths of a mile = 3/5

From the question:

1/10 mile = 1 lap

3/5 mile = x

Cross Multiply

1/10 mile × x = 3/5 mile × 1 lap

x = 3/5 mile × 1 lap/ 1/10 mile

x = 3/5 ÷ 1/10

x = 3/5 × 10/1

x = 6 laps

Therefore, for there fifths of a mile(3/5) he needs to run 6 laps

Answer:

c. is the answer

Answer:

The value of s is "90". A further explanation is given below.

Step-by-step explanation:

The given expression is:

⇒ 10=s÷2+7

i.e,

⇒ [tex]10=\frac{s}{2+7}[/tex]

On solving the above expression, we get

⇒ [tex]10=\frac{s}{9}[/tex]

On applying cross-multiplication, we get

⇒ [tex]10\times 9=s[/tex]

⇒ [tex]90 = s[/tex]

Step-by-step explanation:

Hey there!

Given figure is a triangular based prism. Where the triangle is right angled triangle.

So,

Hypotenuse (h) = 6.5m

Perpendicular (p) =2.5 m

Base (b) = 6m

Length of triangular prism (l) = 10m.

We have;

Lateral surface area= Perimeter*length of prism.

LSA = (6.5+2.5+6) * 10

LSA = 15*10

Therefore, LSA of the shape is 150 m².

Now, Area of base=( 1/2 )*b*p

= (1/2)*(6*2.5)

= 7.5 m²

Therefore, area of base = 7.5 m²

Now, TSA= 2*Area of base+LSA

= (2*7.5 + 150) m²

= 165 m²

Therefore, the Total surface area is 165 m².

Hope it helps....

Answer:

Original cost =70 pounds

Step-by-step explanation:

Let original cost be x,

so original cost = x

[tex]x*\frac{80}{100} = 56[/tex]

[tex]x = 56 /\frac{80}{100}[/tex]

[tex]x = 70 pounds[/tex]

Answer:

(0, 4 ) and ( [tex]\frac{1}{2}[/tex], [tex]\frac{13}{2}[/tex] )

Step-by-step explanation:

Given the2 equations

y = 4x² + 3x + 4 → (1)

y = 5x + 4 → (2)

Substitute y = 4x² + 3x + 4 into (2)

4x² + 3x + 4 = 5x + 4 ( subtract 5x + 4 from both sides )

4x² - 2x = 0 ← factor out 2x from each term

2x(2x - 1) = 0

Equate each factor to zero and solve for x

2x = 0 ⇒ x = 0

2x - 1 = 0 ⇒ 2x = 1 ⇒ x = [tex]\frac{1}{2}[/tex]

Substitute these values into (2) for corresponding values of y

x = 0 : y = 5(0) + 4 = 0 + 4 = 4 ⇒ (0, 4 )

x = [tex]\frac{1}{2}[/tex] : y = [tex]\frac{5}{2}[/tex] + 4 = [tex]\frac{13}{2}[/tex] ⇒ ([tex]\frac{1}{2}[/tex], [tex]\frac{13}{2}[/tex] )

Answer:

  angle 4

Step-by-step explanation:

"Alternate" means the angles are on opposite sides of the transversal. "Exterior" means the angles are outside (not between) the parallel lines. The diagram shows the alternate exterior angles are angle 8 and angle 4.
