Solve the equation for x. x/3 = (2x + 3)/7

Mathematics

Lemur [1.5K]3 years ago

Answer:

<em>Our answer is </em>x=9<em></em>

Step-by-step explanation:

First we will rearrange so we have to divide by 7.

\frac{x}{3}= \frac{2x+3}{7}

Now we will cross multiply.

So...

x*7 \\3*2x+3

Our new equation will look like:

7x=6x+9

Now we have to isolate x.

So we have to subtract 6x from both sides.

7x-6=1x

and

6x-6x=0

Our new equation is:

1x=9

Now divide.

<em>Our answer is </em>x=9<em></em>

<em></em>

<em>Hope this helped!</em>

X = 3

First u cross multiply

7x =3(2x +3)
Multiply parentheses by 3


7x = 6x =9
Move variable to the left

7x - 6x =9
Collect the terms

x = 9

A random sample from the 6th and 7th grade student population was taken to determine which clubs were the most popular.
gtnhenbr [62]

Using the percentage concept, it is found that 25% of 6th graders are involved in the yearbook club.

<h3>What is a percentage?</h3>

The percentage of an amount a over a total amount b is given by a multiplied by 100% and divided by b, that is:

P = \frac{a}{b} \times 100\%

In this problem, 10 out of 10 + 24 + 6 = 40 6th graders are involved in the yearbook club, hence the corresponding percentage is given by:

P = \frac{10}{40} \times 100\% = 25\%

I’m not sure how to solve this. help?

Answer:

The measure of ∠GKH is 27°

Step-by-step explanation:

  • In the isosceles triangle, the base angles are equal in measures
  • The measure of an exterior angle at a vertex of a triangle equals the sum of the measures of two opposite interior angles

In Δ HJK

∵ HJ = JK

→ That means the triangle is isosceles

∴ Δ HJK is an isosceles triangle

∵ ∠JHK and ∠JKH are base angles

→ By using the first rule above

∴ m∠JHK = m∠JKH

∵ m∠HJK = 70°

∵ m∠JHK + m∠JKH + m∠HJK = 180° ⇒ interior angles of a triangle

∴ m∠JHK + m∠JKH + 70 =180

→ Subtract 70 from both sides

∴ m∠JHK + m∠JKH = 110

→ Divide their sum by 2 to find the measure of each one

∴ m∠JHK = m∠JKH = 110 ÷ 2 = 55°

∵ ∠JHK is an exterior angle of ΔGHK at vertex H

∵ ∠HGK and ∠GKH are the opposite interior angles to ∠JHK

→ By using the 2nd rule above

∴ m∠JHK = m∠HGK + m∠GKH

∵ m∠JHK = 55°

∵ m∠HGK = 28°

∴ 55 = 28 + m∠GKH

→ Subtract 28 from both sides

∴ 27° = m∠GKH

∴ The measure of ∠GKH is 27°

Ahmad’s father is 4 times as old as Ahmad. After 5 years, father will be three times as old as Ahmad. Find their present ages
Ilia_Sergeevich [38]

The present age of Ahmed and Ahmed's father is 12 and 36 respectively.

Step-by-step explanation:

Given : Ahmed's father is thrice as old as Ahmed. After 12 years, his age will be twice that of his son.

To Find : Their present age ?

Solution :

Let the Ahmed's age be 'x'.

Ahmed's father is thrice as old as Ahmed.

i.e. Ahmed's father age is '3x'

After 12 years, his age will be twice that of his son.

i.e. 3x+12 = 2(x+12)3x+12=2(x+12)

Solving the equation,

3x+12 = 2x+243x+12=2x+24

x=12x=12

So, Ahmed's age is 12.

Ahmed's father age is 3\times 12=363×12=36

Therefore, The present age of Ahmed and Ahmed's father is 12 and 36 respectively.

B
Gnesinka [82]

Answer:

13

Step-by-step explanation:

We know that a^2+b^2 = c^2  where a and b are the legs and c is the hypotenuse

5^2 + 12^2 = c^2

25+144 = c^2

169 = c^2

Taking the square root of each side

sqrt(169) = sqrt(c^2)

13 =c
