What is the missing number in the equation?

3/10 x ? = 21/10

7 , or 7/1

Step-by-step explanation:

Let ? = x. Set the equation:

(3/10)x = 21/10

Isolate the variable, x. Multiply 10/3 to both sides of the equation:

x * (3/10) * (10/3) = (21/10) * (10/3)

x = 21/10 * 10/3

Simplify the equation. Divide common factors from both the numerator and denominator, and then simplify:

x = (21 * 10)/(10 * 3)

x = (21/3) = 7/1 = 7

x = 7

the length of o'p' is .

step-by-step explanation:

it is given that the quadrilateral m'n'o'p' is the image of quadrilateral mnop after dilation.

the center of dilation is origin and the scale factor is 1.5.

in dilation the image and preimge are similar figures. it means the sides of image and preimage are proportional.

the scale factor is defined as

the scale factor is 1.5.

multiply both sides by op.

note: if the value of op is given, then multiply the value of op with 1.5 to get the length of side o'p'.

therefore length of o'p' is .

sorry

sorry, but im pretty sure its a now that i look at it
