What value of x makes a true equivalent fraction statement x over 40 equals 7 over 56

1 answer:

4 0

X would equal 5 because if you do x over 40 equals 7 over 56, then you could cross multiply and get 56x=280 (7 x 40). Then you do 280 divided by 56 and x would equal 5

Find the value of x when 6 - 3x = 5x - 10x + 8. The value of x is

katrin2010 [14]

Answer:

Step-by-step explanation:

Simplify

6 + -3x = 5x + -10x + 8

terms:

6 + -3x = 8 + 5x + -10x

Combining like terms: 5x + -10x = -5x

6 + -3x = 8 + -5x

Solving

6 + -3x = 8 + -5x

Move all terms containing x to the left, all other terms to the right. (Remember)

Add '5x' to each side of the equation.

6 + -3x + 5x = 8 + -5x + 5x

Combine the like terms -3x + 5x = 2x

6 + 2x = 8 + -5x + 5x

Combine the like terms again -5x + 5x = 0

6 + 2x = 8 + 0

6 + 2x = 8

Then '-6' to each side of the equation.

6 + -6 + 2x = 8 + -6

Combine the like terms: 6 + -6 = 0

0 + 2x = 8 + -6

2x = 8 + -6

Combine the like terms: 8 + -6 = 2

2x = 2

Then divide each side by '2'.

x = 1

Simplifying

x = 1

What is the gcf of 35, 20,15

fgiga [73]

Answer:

Prime factorisation of the numbers -

$\\ \sf \: 35 = 7 \times \underline5 \\ \\ \sf \: 20 = \underline5 \times 4 \\ \\ \sf \: 15 = 3 \times \underline5 \\$

As, we can see that the 5 is common in the both three numbers. So,

GCF,  greatest common factor (35, 20, 15) = 5

What decimal number does point A on the number line below represent? A vertical number line is shown from negative 2.00 to 0 to

grin007 [14]

Answer: 0.25

Step-by-step explanation:

To find : decimal number represented by point A on the given number line.

Given: Vertical number line is shown from negative 2.00 to 0 to positive 2.00.There are tick marks to show increments of 1 over 4.

Point A is plotted at the third tick .

That means, Point A is marked at 1 over 4.

1 over 4 = $\dfrac{1}{4}=0.25$ [divide 1 by 4]

Hence, the point A represents 0.25 on the given number line.

A square with a side length of 18 inches is dilated by a scale factor of 1/3. How long is the side length of the resulting squar

MA_775_DIABLO [31]

Answer:

$6 in$

Step-by-step explanation:

The side length of the square is 18 inches.

If the this square is dilated by a scale factor of $\frac{1}{3}$ , then the length of the resulting square can be calculated by multiplying the scale factor by the side length of the original square.

The side length of the resulting square is $=\frac{1}{3}\times 18=6in$

Therefore the resulting square is 6 inches long.
