i gotchu, x = 14.4

8/x = 5/9 (solve for x)

first you'd cross multiply (property of multiplication)

(8)(9) = (5)x

72 = 5x

then you flip your equation (communitive property)

5x = 72

then you need to eliminate five so you'd divide by 5 (inverse operation)

5x/5 72/5

x = 72/5

so x would be 14.4 since 72/5 is 14.4

(or just 14 since if you rounded it your answer would be 14)

How would you write 8^5 as a multiplication expression? A. 8 × 5 B. 8 × 8 × 8 × 8 × 8 C. 5 × 5 × 5 × 5 × 5 × 5 × 5 × 5

if we ever face a number written in the form of $\underline{x^{n}}$ where x denotes the base and n denotes the exponent or power , we can expand it in the following way -

$x^{n} = x \times x \times x \times.... x ( upto\: " n " \: times )$

therefore ,

$8 {}^{5} = 8 \times 8 \times 8 \times 8 \times 8$

option ( B )

What is the difference between linear pair supplementary angle and straight angle?

Ivenika [448]

They both are 180 degrees.

One possible difference is that a straight angle is just a single angle measuring 180 degrees, while a linear pair supplementary angle are pairs of adjacent angles that add up to 180 degrees.

Assuming the following two triangles are congruent, solve for x if QR =

makkiz [27]

I think you meant the two segments are identical, if so then:

$3x + 16 = 5x - 22 \\ - 2x = - 38 \\ x = 19$
