If x = 2y then solve 5y-x in terms of y find the values of these expressions when y =2​

We know

[tex]\\ \sf\longmapsto tan\theta=\dfrac{Perpendicular}{Base}[/tex]

[tex]\\ \sf\longmapsto tan(<R)=\dfrac{PQ}{PR}[/tex]

The expressions are equivalent to tan R = PQ / PR. Where PQ is perpendicular, and PR is the base.

It is a triangle in which one of the angles is 90 degrees and the other two are sharp angles. The sides of a right-angled triangle are known as the hypotenuse, perpendicular, and base.

The triangle PQR is given,

∠R=90°

As we know that the tangent is the ratio of the perpendicular and base.

Geometry is defined as the branch of mathematics that is concerned with the size, shape, and orientation of two-dimensional figures.

When P is right-angled and R is theta, PQ is perpendicular, and PR is the base if P is right-angled.

tanθ=P/B

tanR=PQ / PR.

Thus, the expressions are equivalent to tan R = PQ / PR. Where PQ is perpendicular, and PR is the base.

Answer:

Since both have equal length

9x - 2 = 6x + 13

9x - 6x = 13 + 2

3x = 15

x = 15/3

x = 5

Length of BC = 6(5) + 13 = 43 cm

Step-by-step explanation:

Solution,

AB=9x-2

BC=6x+13

Now,

AC=AB+BC

=9x-2+6x+13

=15x+11

1 dozen = 12

3 dozen = 3 x 12 = 36

36/8 = 4.5

Different type of spaghetti dinners is 8

What is combination ?

"The number of possible arrangements in a collection of items where the order does not matter."

For 4 different shaped of noodles = ⁴c₁

                                             ⁴c₁ = 4        

For two kinds of cheese = ²c₁

                                         ²c₁ = 2

Answer and Step-by-step explanation:

15.  [tex]-\frac{27}{20}[/tex] or [tex]-1\frac{7}{20}[/tex]

-1.35 = -135/100 = [tex]-1\frac{35}{100}[/tex]  (Mixed number)

Multiply the number by 100, then divide the number by 100 (but keep it in fraction form).

-1.35 x 100 = -135

[tex]-\frac{135}{100}[/tex] = [tex]-\frac{27}{20}[/tex]

(Mixed Fraction = . To check, multiply the 20 by the 1, then add 7, to get -27/20)

18. [tex]\frac{49}{11}[/tex] or [tex]4\frac{5}{11}[/tex]

4.45 = 49/11 = [tex]4\frac{5}{11}[/tex]

4.4545.....

Multiply the number by 100 (because there is 2 numbers being repeated.

445.4545....

Now subtract by the original number.

445.4545....

-   4.4545....

441.00

Write this as an equation:

(100 x fraction) - fraction = 441           (100 x fraction) - fraction = 99 x fraction

99 x fraction = 441   (Divide both sides by 99)

fraction = [tex]\frac{441}{99}[/tex] (which simplifies down to [tex]\frac{49}{11}[/tex])

Step-by-step explanation:

There are 60 students that prefer soccer

The first step is to determine the percentage of students that prefer soccer The percentage of students that prefer soccer = 100 - (53% + 26% + 15% ) = 6%

6% of the students surveyed prefer soccer

The second step is to determine the number of students that prefer soccer

Number of students that prefer soccer = (percentage of students that prefer soccer / 100) x total number of students surveyed

[tex]\frac{6}{100}[/tex] × 1000 = 60 students

Answer:

Yes

Step-by-step explanation:

Both arguments are squared so the equation are in the form of a circle.

A lotus is a point that is equidistant from some fixed point of a conic section. This is a circle so the fixed point is called a center of the circle.

The center of the circle is equidistant from any point on the circumference of the circle. In order for a point to be on the circle, it must satisfy the circle equation.

[tex] {x}^{2} + {y}^{2} = {r}^{2} [/tex]

Let plug in what we know

[tex]3 {}^{2} + ( - 4) {}^{2} = {5}^{2} [/tex]

[tex]9 + 16 = {5}^{2} [/tex]

So 3,-4 is on the locus of the circle.

Let's assume that the original length of the piece of board is L.

Now you cut two pieces that are 3.4 ft long, so the remaining piece of board is:

L - 3.4ft - 3.4ft = L - 6.8ft long.

Now we know that the remaining must be 2.35 times longer than the pieces of 3.4 ft, then we have the equation:

( L - 6.8ft) = 2.35×3.4ft

solving that for L we get:

L  = 14.79ft

Rounding to the nearest tenth, we get:

L = 14.8ft

You should buy a piece of board that is 14.8 feet long.
