If The Triangles Are Similar, Find The Value Of X.

Answers

Answer 1

Answer:

x=25

Step-by-step explanation:

the triangles are similar

so as we know

when two triangles are similar the rotio of triangles is equal

now let's solve it

to understand the solving stepsyou need to know aboutequation with fractionPEMDAS

according to the question

[tex] \frac{24}{30 } = \frac{x + 7}{2x - 10} [/tex]

[tex] \frac{4}{5} = \frac{x + 7}{2x - 10} [/tex]

[tex]4(2x - 10) = 5(x + 7) \: (cross \: multiplication)[/tex]

[tex]8x - 40 = 5x + 35[/tex]

[tex]8x - 5x = 35 + 40[/tex]

[tex]3x = 75[/tex]

[tex]x = 25[/tex]

A hot air balloon holds 2,200 cubic meters of helium. The density of helium is 0.1785 kilograms per cubic meter. How many kilograms of helium does the balloon contain, rounded to the nearest tenth of a kilogram?

Answers

Answer:

392.7

To get the answer multiply Density * Volume

Mass = 0.1785 * 2200

Mass = 392.7

The mass of the helium with a density of 0.1785 kilograms per cubic meter and volume of 2,200 cubic meters  is 392.7 kg

What is density?

The density of a substance is its mass per unit volume. It can be represented mathematically as follows:

density = mass / volume

Therefore,

mass of the helium = ?

density of the helium = 0.1785  kilograms per cubic meter

volume of helium = 2,200 cubic meters

Therefore,

mass = density × volume

mass =  0.1785 × 2200

mass = 392.7 kg

elimination

Answers

Answer:

The solution to the system of equations is:

[tex]x=10,\:y=4[/tex]

Step-by-step explanation:

Given the system of equations

[tex]\begin{bmatrix}5x-4y=34\\ -x+8y=22\end{bmatrix}[/tex]

Multiply -x+8y=22 by 5:  -5x+40y=110

[tex]\begin{bmatrix}5x-4y=34\\ -5x+40y=110\end{bmatrix}[/tex]

so adding the equations

[tex]-5x+40y=110[/tex]

[tex]+[/tex]

[tex]\underline{5x-4y=34}[/tex]

[tex]36y=144[/tex]

solve 36y = 144 for y:

[tex]36y=144[/tex]

divide both sides by 36

[tex]\frac{36y}{36}=\frac{144}{36}[/tex]

Simplify

[tex]y=4[/tex]

For 5x-4y=34 plug in y=4

[tex]5x-4\cdot \:4=34[/tex]

[tex]5x-16=34[/tex]

Add 16 to both sides

[tex]5x-16+16=34+16[/tex]

Simplify

[tex]5x=50[/tex]

Divide both sides by 5

[tex]\frac{5x}{5}=\frac{50}{5}[/tex]

Simplify

[tex]x=10[/tex]

Therefore, the solution to the system of equations is:

[tex]x=10,\:y=4[/tex]
