The sum of three numbers is 56. The second number is 2 times the third. The first number is 8 less than the third. What are the numbers?

X = 8

Y = 32

Z = 16

Step-by-step explanation:

X + Y + Z = 56

Y = 2Z

X = Z – 8

Substitute the values from the second and third equation into the first equation:

Z – 8 + 2Z + Z = 56

Simplify

-8 + 4Z = 56

4Z = 64

Z = 16

So if Y = 2Z, Y = 2(16) = 32

And if X = Z – 8, X = 16-8 = 8

40 x 50 = 2000

step-by-step explanation:

c. 27 units.

step-by-step explanation:

we are told that in circle a, ∠bae ≅ ∠dae.

we can see from our given diagram that in and ;

, as these are radii of our given circle.

therefore, by sas congruence postulate.

hence, side be will be equal to side de as corresponding parts of congruent triangles are congruent. so we can set an equation to find the value of x as:

now let us substitute x=17 in the expression for the length of be.

therefore, length of be will be 27 units and option c is the correct choice.
