18.find the value of x rounded to the nearest tenth. a.15.3 b.12.0 c.11.0 d.5.3

Cross multiply:

6 * 8 = 9*x

48 = 9x

x = 48/9

x = 5.3

The answer is D.

D) x = 5.3 .

Step-by-step explanation:

Given  : Two triangles.

To find : .Find the value of x rounded to the nearest tenth.

Solution : We have given two similar triangle

By the property of similar ratio of sides are equal.

Then,

.

On cross multiplication

6 * 8 = 9 * x .

48 = 9 *x

On dividing by 9 and switching sides.

x = .

x = 5 .33

x = 5.3

Therefore, D) x = 5.3 .

the mistake in the pattern is that :

b. the decimal point was moved one too many place values each time

the correct pattern could be made by :

b. moving the decimal point to the right the same numbers of place values as the exponents
