Can anyone help me with this please.

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:

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]

Answer:

46.75 in.2, 61.75 in.2

Step-by-step explanation:

its in your notes/lesson on gradpoint

Answer:

Its nothing complicated, you just have to combine all the like terms, just make sure the lvariables are the same before combining of course.

so assuming the gaps missng are exponents

the solution is the same exact thing

it can’t be simplified anymore since 16q^3 or -48q^2 can’t due to different exponents which thefore can’t combine

same with 32 q, nothing combines

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:

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:

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

Step-by-step explanation:

Answer:

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°

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

Answer:

48

Step-by-step explanation:

Given ratio of males to females at a party is 3 : 5.

Let the numbers of males and females be 3x and 5x respectively.

According to the given description:

No of females = No of males + 13

Therefore,

5x = 3x + 12

5x - 3x = 12

2x = 12

x = 12/2

x = 6

No of people at the party

= 3x + 5x

= 8x

= 8*6

= 48
