Answer:

9x + 36 = 63

Step-by-step explanation:

Let x represent the number of toys that each club member donated.

There are 9 students in a service club.

If each club member donated 4 children's books for the baskets, it means that the total number of books donated by the club members would be

9 × 4 = 36

If each club member also donated an equal number of toys. It means that the total number of toys donated by the club members would be

9 × x = 9x

A total of 63 items were collected for the baskets. Therefore, the linear equation that you can use to find how many toys each club member donated would be

9x + 36 = 63

Answer:  25

Step-by-step explanation:

Let x be the amount of fish in Ju Long's aquarium.

We know that 24% of x is equal to 6.

We can now set up an equation.

24% * x = 6

24% as a decimal is 0.24"

0.24x = 6

We can divide both sides by 0.24:

x = 25

The solution is, 25 fish are in Ju long's aquarium.

An equation is a  mathematical statement that is made up of two expressions connected by an equal sign.  In its simplest form in algebra, the definition of an equation is a mathematical statement that shows that two mathematical expressions are equal.

here, we have,

given that,

Ju long has 6 guppies in his aquarium.

This is 24% of the fish in the aquarium.

Let x be the amount of fish in Ju Long's aquarium.

We know that 24% of x is equal to 6.

We can now set up an equation.

24% * x = 6

24% as a decimal is 0.24"

0.24x = 6

We can divide both sides by 0.24:

x = 25

Answer:

3 and -14

Step-by-step explanation:

Find the factors of -42 and add them to see what they give:

1 × -42 = 42, -41

2 × -21 = 42, -19

3 × -14 = 42, -11

6 × -7 = 42, -1

The second to last is right so the numbers are 3 and -14

Answer:

B) x-5y=20

Step-by-step explanation:

y-y1=m(x-x1)

y-(-5)=1/5(x-(-5))

y+5=1/5(x+5)

y=1/5x+5/5-5

y=1/5x+1-5

y=1/5x-4

1/5x-4=y

5(1/5x-4)=5y

5/5x-20=5y

x-20=5y

x-5y=20

4. [tex]a^{8}b^{10}c^{15}[/tex]

Step-by-step explanation:

When dividing a monomial by another monomial, we divide the coefficients and apply the quotient law of exponents, x m ÷ x n = x m – n to the variables. If both the monomials have negative coefficients, the negative signs cancel out and the answer so obtained will be having a positive coefficient only.

For example, the binomial 2x +4 can be multiplied by the monomial 4x so that (2x) (4x) equals 8x2 and 4·4x equals 16x, using the distributive property. Therefore, (2x +4) (4x) equals 8x2 + 16x.Mar 15, 2016

Use the Quotient Property. When we divide monomials with more than one variable, we write one fraction for each variable. Use fraction multiplication. Simplify and use the Quotient Property.

A diagram of the geometry is helpful. Our understanding of your description is shown in the first attachment. The second attachment shows how the various angles relate to each other. An exterior angle and its adjacent interior angle are a linear pair, so are supplementary.

__

1. BEC is an exterior angle -- False, it is an interior angle

2. DEC is an exterior angle -- True

3. ABE and EBC are supplementary -- True, they are a linear pair

4. BCF and DEC are supplementary -- False, they are unrelated exterior angles

5. BEC is a remote interior angle to BCF -- True

Janae and Jerome each have either 3, or 4 or 5 marbles. Option C, D and E are correct.

Given that the number of marbles has:

Janae = m

Jerome  = m

Gwen = 4(m+2)

John = 8m+4

John has more marbles than Janae, Jerome, and Gwen combined, So this can be written as,

[tex]8m+4 \geq m + m + 4(m+2)[/tex]

[tex]8m+4\geq 2m + 4m+8[/tex]

[tex]8m+4 \geq 6m+8[/tex]

[tex]2m\geq 4[/tex]

[tex]m\geq 2[/tex]

It means that the value of m is greater than 2, it can be 3, 4 or 5.

Hence we can conclude that Janae and Jerome each have either 3, or 4 or 5 marbles. Options C, D and E are correct.

The intensity of soundwave at a distance of 12 miles is 222.22 miles.

The link between two variables whose ratio is equal to a constant number is known as a direct proportional, while the multiplication of two variables whose ratio is equal to a constant number is known as an inversely proportional.

It is given that the intensity of a radio signal from the radio station varies inversely as the square of the distance from the station. therefore, the relation between the intensity of the radio wave(I) and distance(r) can be written as,

[tex]I\propto \dfrac{1}{r^2}\\\\\\I=k \dfrac{1}{r^2}[/tex]

Now, it is stated that the intensity of the radio wave at a distance of 2 miles is 8000 units, therefore, substituting the value in the above equation to get the value of the constant,

[tex]I=k\dfrac{1}{r^2}\\\\8000=k\dfrac{1}{2^2}\\\\8000=k\dfrac{1}{4}\\\\k = 8000 \times 4 = 32,000\rm\ units[/tex]

Thus, the value of the constant k is 32,000 units, and the equation of the intensity of the radio signal can be written as,

[tex]I=\dfrac{32,000 }{r^2}[/tex]

Further, the intensity of soundwave at a distance of 12 miles will be equal to,

[tex]I=\dfrac{32,000 }{r^2}\\\\I=\dfrac{32,000 }{12^2}\\\\I=\dfrac{32,000 }{144}\\\\I = 222.22\rm\ units[/tex]

Hence, the intensity of soundwave at a distance of 12 miles is 222.22 miles.

(x - 6)^2 = 0 or (x + 2)^2 = 0

Take the square root of both sides:

x - 6 = 0 or (x + 2)^2 = 0

Add 6 to both sides:

x = 6 or (x + 2)^2 = 0

Take the square root of both sides:

x = 6 or x + 2 = 0

Subtract 2 from both sides:

Answer: x = 6 or x = -2

Step-by-step explanation: the answer is x= 6  or = -2

Answer:

The age of Jamal is 8 years.

And the age of his father is 32 years.

Step-by-step explanation:

=> let the age of Jamal be x and his father's age be y

=> so , A.T.Q ,

x+y = 40....i)

Find the value of y from here , that's y = 40-x .....

Now, After 4 years ,

=> 3(x+4) = (y+4)

=> 3x+12 = y+4

=> 3x+8 = y ...ii)

putting the value of y in equation ii)

=> 3x+8 = 40-x

=> 3x+x = 40-8

=> 4x = 32

=> x = 8

now ,

=> y = 40-x

=> y = 40-8

=> 32
