Which answers would be possible first steps?

Answer:

A

Step-by-step explanation:

Let the two sides of the rectangle be x and y.

Then the perimeter will be:

[tex]2x+2y=P[/tex]

Since the perimeter is 54:

[tex]2x+2y=54[/tex]

We know that one side of the rectangle is 3 inches shorter than the other.

Let y be the shorter side. It is 3 less than x.

Therefore:

[tex]y=x-3[/tex]

Then by substitution, we acquire:

[tex]2x+2(x-3)=54[/tex]

The answer is A.

Answer:

x = 12, y = 4

Step-by-step explanation:

For the triangles to be congruent by HL , then

x = y + 8 → (1)

4y = x + 4 → (2)

Substitute x = y + 8 into (2)

4y = y + 8 + 4

4y = y + 12 ( subtract y from both sides )

3y = 12 ( divide both sides by 3 )

y = 4

Substitute y = 4 into (1)

x = 4 + 8 = 12

Answer:Convert it to the slope intercept form by solving for y . Add x to both sides. Divide both sides by 5 . y=15x−1 is the slope intercept form of a linear equation, y=mx+b , where m is the slope, 15 and b is the y-intercept, −1

The answer is below

Step-by-step explanation:

If the quadrilateral below is a rhombus, find the missing measures.

MK = 24, JL = 20, and mZMJL = 50°

Solution:

A rhombus is a quadrilateral (has four sides and four angles) such that all the sides are of equal length.

The diagonals of a rhombus bisect each other.

NK = MK / 2 (diagonals of a rhombus bisect each other)

NK = 24 / 2 = 12

NL = JL / 2 (diagonals of a rhombus bisect each other)

NL = 20 / 2 = 10

In triangle MNL, ∠N = 90°

MN = NK = 12 , NL = 10. Using Pythagorean theorem:

ML² = MN² + NL²

ML² = 12² + 10²

ML² = 244

ML = √244

ML = 2√61 = 15.62

JM = ML  = 15.62 (all sides of a rhombus are equal)

∠KNL = 90° (diagonals are perpendicular bisectors)

∠KJL = ∠MJL (diagonals bisect angles)

∠KJL = 50°

∠MJK = ∠KJL + ∠MJL = 50 + 50 = 100°

∠MJK = ∠MLK (opposite angles are equal)

∠MLK = 100°

∠NJK + ∠JNK + ∠JKM = 180° (sum of angles in triangle)

50 + 90 + ∠JKM = 180

∠JKM = 40°

∠JKL = 2 * ∠JKM (diagonal bisect angle)

∠JKL = 2 * 40

∠JKL = 80°

∠JKL = ∠JML (opposite angles are equal)

∠JML = 80°

Answer:

45%

Step-by-step explanation:

The computation of the percentage increase from the first week is shown below:

Given that

In the first week there is 3,200 views

And, in the second week, there is 4,640 views

So, the percentage increase is

= (Second week views - first week views) ÷ (first week views)

= (4,640 - 3,200) ÷ (3,200)

= 45%

Answer:

Answer: C dont ask me why

Step-by-step explanation:

Answer:

x = 5, y = 2

Step-by-step explanation:

First, isolate y in the top equation.

[tex]y = -5.3x+28.5[/tex]

Next, substitute y in the bottom equation.

[tex]4.2x + 3.1(-5.3x + 28.5) = 27.2[/tex]

[tex]5.3x + y = 28.5[/tex]

Simplify.

[tex]4.2x + -16.43x + 88.35 = 27.2[/tex]

Combine like terms.

[tex]-12.23x + 88.35 = 27.2[/tex]

Isolate x on one side.

[tex]-12.23x = -61.15[/tex]

Isolate x.

[tex]x = 5[/tex]

Substitute x into [tex]5.3x + y = 28.5[/tex]

[tex]5.3(5) + y = 28.5[/tex]

Simplify.

[tex]26.5 + y = 28.5[/tex]

Isolate y.

[tex]y = 2[/tex]

[tex]x = 5 \\y = 2[/tex]

It would take her 4590 seconds to jog round the track 51 times

Speed is the ratio of the total distance travelled to total time taken. It is given by:

Speed = distance / time

Kat uses 40 seconds to jog 160 m, hence:

Speed = 160 m / 40 s = 4 m/s

The track length = 140 m + 2 * (π * 70) = 360 m

Time taken to jog round the track (t) is:

4 m/s = 360 m / t

t = 90 s

To jog round the track 51 times, time taken = 51 * 90 s = 4590 seconds

It would take her 4590 seconds to jog round the track 51 times

Step-by-step explanation:

Answer:

the length and width be 13.33 feet and 34.67 feet respectively

Step-by-step explanation:

The computation is shown below:

Let us assume the width be x

So, the length be 2x + 8

As we know that

The perimeter of the rectangle = 2(length + width)

96 = 2(2x + 8 + x)

96 = 4x + 16 + 2x

96 - 16 = 6x

80 = 6x

x = 80 ÷ 6

= 13.33 feet

So, the length would be

= 2 × 13.33 + 8

= 34.67 feet

Hence, the length and width be 13.33 feet and 34.67 feet respectively
