The triangles in the image are similar.<br> Solve for x.<br> A) 7 <br> B) 6 <br> C) 10 <br> D) 5

Natalka [10]

ANSWER

A) 7

EXPLANATION

The given triangles are similar

Hence the corresponding sides are in the same proportion.

$\frac{3x + 4}{30} = \frac{30}{36}$

Simplify the right hand side:

$\frac{3x + 4}{30} = \frac{5}{6}$

Cross multiply;

6(3x+4)=5×30

Expand

18x+24=180

18x=150-24

18x=126

$x = \frac{126}{18} = 7$

Six less than six timesa number is 12

vovangra [49]

Six (6) less than (subtraction) six (6) times (multiplication) a number (n) is (=) 12.

6n - 6 = 12

To solve, add 6 to both sides

6n = 18 Dviide both sides by 6
n = 3
