Answer:

-6x-4

Step-by-step explanation:

Given:

The system of equations is

[tex]8x+9y=36[/tex]

[tex]3x+4y=16[/tex]

To find:

The solution of the given system of equations using the substituting method.

Solution:

We have,

[tex]8x+9y=36[/tex]           ...(i)

[tex]3x+4y=16[/tex]            ...(ii)

From (ii), we get

[tex]3x=16-4y[/tex]

[tex]x=\dfrac{16-4y}{3}[/tex]          ...(iii)

Putting this value in (i), we get

[tex]8\left(\dfrac{16-4y}{3}\right)+9y=36[/tex]

Multiply both sides by 3.

[tex]8(16-4y)+27y=108[/tex]

[tex]128-32y+27y=108[/tex]

[tex]-5y=108-128[/tex]

[tex]y=\dfrac{-20}{-5}[/tex]

[tex]y=4[/tex]

Putting y=4 in (iii), we get

[tex]x=\dfrac{16-4(4)}{3}[/tex]

[tex]x=\dfrac{16-16}{3}[/tex]

[tex]x=\dfrac{0}{3}[/tex]

[tex]x=0[/tex]

Therefore, the solution of given system of equations is (0,0).

Answer:

21°

Step-by-step explanation:

We can prove these two triangles congruent by the HL (Hypotenuse-Leg) theorem. Then, we know that m<YQR is congruent to m<PQY. We can then use their given values to form an equation.

5x+6=16x-27

Continue to solve . . .

33 = 11x

x=3

Therefore, we can plug this value of 3 into the expression for the value of m<YQR, and you will get

(16 x 3) - 27, which is equal to 21°.

Answer:

The vertical line test can be used to determine whether a graph represents a function. ... If we can draw any vertical line that intersects a graph more than once, then the graph does not define a function because that x value has more than one output. A function has only one output value for each input value.

Step-by-step explanation:

The diagonals are equal length:

[tex]6x - 14 = 8x - 20\\-2x = -6\\x = 3[/tex]

[tex]BD = 6x - 14\\BD = 6 * 3 - 14\\BD = 18 - 14\\BD = 4[/tex]

The length of diagonal BD in rectangle ABCD is 4 units.

A rectangle is a quadrilateral (has four sides and four angles) in which opposite sides are parallel and equal to each other. All the angles of a rectangle measure 90 degrees.

The diagonals of a rectangle are equal to each other.

AC = BD (diagonals of rectangle are equal)

6x - 14 = 8x - 20

2x = 6

x = 3

BD = 6(3) - 14 = 4 units

The length of diagonal BD in rectangle ABCD is 4 units.

The sum is 1225

Solution : 

The numbers from 150 to 200 divisible by 7 are 154,161 ,168,…., 196

Here, a=154,d=7a=154,d=7 and tn=196tn=196

tn=a+(n−1)dtn=a+(n-1)d …(Formula )

∴196=154+(n−1)×7∴196=154+(n-1)×7 …(Substituting the values )

∴196−154=(n−1)×7∴196-154=(n-1)×7

∴427=n−1∴427=n-1 ∴n−1=6∴n-1=6 ∴n=7∴n=7

Now, we find the sum of 7 numbers.

Sn=n2[t1+tn]Sn=n2[t1+tn] ...(Formula )

=72[154+196)=72[154+196)

=72×350=72×350

=7×175=7×175

Answer:

147.84 g/L

Step-by-step explanation:

Paso 1

El volumen del objeto se calcula como:

0.485L - 0.350L

= 0.135 litros

Paso 2

Convertimos la masa del objeto de libras a gramos

1 libra = 453.592 gramos

0.044 libras (lb) = x

Cruz multiplicar

x = 0.044 × 453.592 gramos

x = 19.958064 gramos

Paso 3

Densidad del objeto

= Masa (gramos) / Volumen (L)

= 19.958064 gramos / 0.135L

= 147.837511111 g / L

Aproximadamente = 147.84 g / L

Por lo tanto, la densidad (g / mL) del objeto es 147.84 g / L

Answer: ( x -2 ) inches

Step-by-step explanation:

Let x  = length of skirt.

Given: Christi first cuts 7 inches off the bottom of the skirt and then adds a 5-inch ruffle to the skirt's remaining bottom edge.

Cutting of length will be represented by a negative integer.

The expression best represents the final length of the skirt = x-7+5 inches

= x -2 inches

Hence, the expression best represents the final length of the skirt = ( x -2 ) inches

Answer:

X = 12.21

Step-by-step explanation:

Since this is a right triangle, use the formula A^2 + B^2 = C^2 and plug in appropriate values.

(10)^2 + (7)^2 = C^2

100 + 49 = C^2

149 = C^2

12.2065 = C

Rounded to two decimal places, this makes X equal to 12.21.

The required value of x is 12.21 for the given right triangle.

A right triangle is defined as a triangle in which one angle is a right angle or two sides are perpendicular.

Pythagoras's theorem states that in a right-angled triangle, the square of one side is equal to the sum of the squares of the other two sides.

Since this is a right triangle, use the formula A² + B² = C² and substitute appropriate values.

(10)² + (7)² = x²

100 + 49 = x²

149 = x²

x = √149

x = 12.2066

Rounded to two decimal places,

x = 12.21

Therefore, the required value of x is 12.21.

Answer:

y=70

x=55

Step-by-step explanation:

In an equilateral triangle, all the angles measure 60 degrees. Knowing this, we can set the following equations:

[tex]60=y-10\\60=x+5[/tex]

[tex]60=y-10[/tex]

Add 10 to both sides

[tex]60+10=y-10+10\\70=y[/tex]

[tex]60=x+5[/tex]

Subtract both sides by 5

[tex]60-5=x+5-5\\55=x[/tex]

I hope this helps!
